I am working on a Wordpress site (a modified 2012 theme) for a client that is rendering incorrectly in IE8. Everything looks great in IE9+, as well as current versions of Chrome, FF, Safari, etc. I have looked around at some of the suggestions posted to fix the problem but I'm not quite sure where mine begins. The whole page is considerably broken. If anyone can provide me with some clues it would be a huge help. Thanks!
My Site
Edit: I'm noticing some of my styles are not being applied, specifically to top-nav and my footer. Others appear to have most if not all styles mostly intact. I've read that media-queries are not supported in IE8, but I don't see how that could be related. I am also reading that only 31 stylesheets can be applied, but I don't believe I am using nearly that many.
I had a project a while back where I have built an intranet and was nearly finished with the strap when I realized that most of the users rely on IE8; it was a shocking experience, can tell you that. That just as a preamble, so I know what your into.
I have wasted a lot of time so to safe yours (maybe), here what I would look for and probably do:
Install IE8 if you haven't already. There's a lot of tools which can help you with that like IE Tester as well as an integration installation from Microsoft directly to switch between versions
Eradicate the current errors first before you start working on the specific IE8 issues (as #markratledge already mentioned)
If you want to have HTML5 elements working as well then I recommend the HTML5.js Enabling Script
You have definitely too many HTTP Referrers (even for modern browsers), in IE8 (especially on a slower machine) it's sometimes deadly (Your page may load fast, however the rendering time is extremely long (+/- 6-20 seconds))
Combine and minify CSS and JScripts
There are a lot of services around the net where you put in your raw data and it compiles you a minified version, or server-side like Minify for PHP5
Move most scripts to the bottom to counterfeit rendering issues in IE8
Make a unique .css only for IE8 or use hacks, if really needed in your main, however you prefer (quick'n'dirty solution though)
IE8 and the X-UA-Compatible situation
How IE8 Determines Document Mode
I'm not too sure, but I think Mootools and jQuery together may create a conflict in older IE's (assumption)
Fix your code errors, in particular the JS call above the doctype. Anything above the doctype throws IE into quirks mode
Especially IE8 will get really hard on you for little mistakes inside the code, I have even seen script-includes not working because of being positioned lower than another in the code (while any other browser doesn't really care). It will take you at least a good bunch of hours to fix/erase all those errors and to make it compatible for IE8< users.
Beware that most clients (at least from my experience) don't (want to) understand browser compatibility issues like this one (It has to work!) or if really needed then make them understand that some features may be jeopardized/incomplete in the specific browser, herein.
There's plenty more you can do, but that depends on the deadline/timespan you have.

I know that there are several very similarly-related questions on this website, however after reviewing the play, I believe this question is unique in its own right. If someone can find and provide evidence of an exact dupe of my question, I will withdraw it myself (so please just don't downvote this!).
I am a Java developer, not a web developer. But, as is the case in so many families where there is one person who becomes the designated family "computer guy", my Java development skills have been mistaken for web development skills, and I somehow got roped into building a website for my parents to help them sell their house.
So, like any web development newbie, I wrote the HTML/CSS myself (by hand, sans editor like DW or Expression, etc.) and tested it against FireFox 3.x. All looked great, and we deployed/launched.
Now we're getting negative feedback from everyone and their dog stating that the site isn't rendering properly in other browsers, browser versions, or on FireFox installations running on different operating systems. Similarly, the site is apparently a total mess when being viewed through a smart phone or tablet device.
Now I could dive in and write a whole bunch of messy, nasty, painstakingly-tedious edits to my CSS rules, that basically say: do X when browser is Y, etc. But I am hoping that out there is a tool that can put all my fears to rest.
What I'm looking for is a tool that could take my valid CSS files, and use them to generate CSS rules that will be compatible with a high percentage of all common browsers/versions.
Alternatively, if I have to re-write my CSS from scratch, it would be nice to have a tool that allows me to write/design once, deploy many, so that I only have to focus on the design of a single CSS file, but the code that gets generated is multi-browser compatible.
It sounds like DreamWeaver kind of does this, but you have to choose from one of 16 pre-existing templates.
My wife is a graphic designer, and made the website pretty sweet (not cookie cutter). It was a nightmare trying to figure out what CSS rules to use to implement her design. So any tool that forces you to choose between templates is not an option.
Is there any hope for me, or do I banish myself from my family in shame right now?
css is a mess, no way to automatically doing it right. saying that I would say there are tools that would walk with you the proper way.
1. use the meta tag:
http-equiv="X-UA-Compatible" content="IE=8" (encpsulate as a meta tag - SO won't display if I wrote it as a valid tag)
to force IE to render with it's most modern engine, that would solve some problems.
2.begin your css with normalize.css - that would eliminate some of the cross browser problems - because it resets your css (better and more modern the reset.css)
I'll second the GWT if you come from the java dev world. although It's a framework to learn with it's own quirks. another possible web framework is Grails - a nice java/groovy port of the mighty Ror.
Less or Scss won't automatically solve your basic problem - which is browser compatibily - but are a better and simpler way to write css
remember that most css3 properties aren't support equally in all browsers (and in IE almost not supported) - use them only with graceful downgrade option with supported js or css -when Modernizr js library can give you pretty good property support detection for various browsers
don't go dreamweaver - it produces terrible code
use csslint to check for valid css and common css pitfalls
If you must use cutting edge web rendering with html5+css3 elements you should look into chrome frame -that would enable older browser better support of your site - although I believe this may be an overkill for a simple sell-my-house kind of site.
use a css framework to prototype- it would give you better css, good basics and resets and good boilerplate - maybe bootstrap or something similiar (didn't try most of them but the internet is crowded with those.
good luck
Check out modernizr. http://www.modernizr.com/docs/
You want to get into the position of checking for features and not browsers.
Here's an excellent site to check your site with alternative browsers:
http://www.browserstack.com/
Less (http://lesscss.org/) will help you with a lot of CSS3 functions.
However, good CSS code simply works on all browsers. There are some CSS concepts that must always be avoided as much as possible (absolute positioning, excessive floats, using the wrong elements for a task, etc) and your code will work better.
In the many years I have programmed I only needed browser-specific code in the first two years. Then I grew up and learned which CSS code not to use and when it was possible to use them. It has been my experience that properly written CSS code works on all browsers, and if it doesn't it will at least get the basic concepts right (eg. a few pixels may be wrong or some effects, but the site still works well).
Several things come to mind that may help your case:
Forget about IE6, that one will give you trouble no matter how much effort you put into the site.
Make sure you have a good doctype (html5 or xhtml would be good).
Try out html5 reset, it tries to make sure all browsers behave the same.
The aforementioned reset also includes modernizr to bring older browsers up to speed
Finally: accept (some even say "embrace") that different browsers render things slightly different. Getting every pixel exactly the same in each browser will be near impossible.
I hate to put this into the world, but it sounds like you need Adobe Muse.
There is no equal to a good developer who will write clean cross browser code, but if you just want to get the site done check out the beta: http://labs.adobe.com/technologies/muse/
What I'm looking for is a tool that could take my valid CSS files, and
use them to generate CSS rules that will be compatible with a high
percentage of all common browsers/versions.
Unfortunately there's no such a tool and you have to debug and test your website for cross-browser compatibility manually. The best way i've found for cross-browser testing it to install and test different versions of browsers in several virtual machines.

I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well.
Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?
Many times WYSIWYG programs don't generate code that results in reliable, consistent renderings. However, there are a few things you can do to check your site's consistency.
You can use a program like Adobe BrowserLab (there's a free trial right now) to automatically render your page in multiple browsers side by side
You can use the w3 Validator to make sure that your code is standards compliant. If your code isn't standards compliant, then you will likely have issues across browsers.
Note that you can force asp.net to generate XHTML Transitional- or Strict-compliant code (if that's the standard you choose to implement) via the web.config file. Use the directive
<xhtmlConformance mode="Transitional"/>
if you want to enable this behavior.
Was your code rendering fine in those browsers before you sent it off to the .NET guy? If so, the programmer is doing something to muck up your work. ASP .NET won't change the way your code renders... it's simply the Windows equivalent of PHP (simply put).
I would suggest (if you haven't already) testing your code before hand-off to verify proper rendering. Take some screenshots, and if after sending your code to this developer things break, you can point out that it was working until he started messing with your markup. If that ends up being the case, at least you know it wasn't you. If it was, then we have more work to do. :)
Can you provide any samples?
The html source is showing me two completely different pages as well.
That sounds like your asp.net guy is doing something wrong there. You can use asp.net to do browser-dependant rendering, but it sounds more like his job is to just make the site render what you gave him, and it's usually better to get your html and css right to begin with.
I need to upgrade a ASP.NET website for IE8. it works fine in IE6, but not in IE8. I don't want to run it in any backward compatibility mode. I would like to make any code changes that are required to make it fully compliant with IE8/Firefox. what is the best and/or easiest way to do that? is it just a case of going through each of the things that are broken and fixing them one by one or is there a more efficient way to fix these issues (some kind of utility??). thanks in advance.
Well there is no tool or utility to fix cross browser compatibility issues. You can make use of firebug(firefox) and IE developer toolbar to identify the points where the website is breaking.
But the good part is that you are upgrading from IE6. I dont think there will be major hiccups or problems making the website compatible with IE8 since its much better in rendering HTML as compared to IE6.
If you have expression web, you could use SuperPreview: http://expression.microsoft.com/en-us/dd565874.aspx
THis is a great tool that allows you to compare you site in different browsers.
Yes, you do have to go through each browser incompatibility bug and fix it for that browser. A bug can be fixed in 3 ways (listed in my order of preference):
Start with a very compliant browser, then look at the page in other browsers (I focus on Chrome/Safari/Firefox/IE6-7-8-9)
Use different CSS technique, that ends up rendering the same in all browsers
Use IE Conditional Comments to bring in another CSS for that browser leveraging the CSS "Cascade"
Use CSS Hacks as a last resort (usually only for Firefox or something)
But "go through each browser" can be the tricky part! There are some tools to help.
#Brian mentioned SuperPreview for Expression Web (+1), but there's also a free version of SuperPreview for Internet Explorer for those who don't have Expression Web.
You can compare different versions of IE on the same machine (hard before this product). Microsoft claims this sub-set of the Expression Web product will always be free (since they feel bad about IE6!).
IE6-7-8-9 tool is good enough for me, because I tend to focus on all versions of IE, but only the latest versions of Chrome/Safari/Firefox.
But if you must test against multiple versions of other browsers:

(Although Litmus seems to have dropped general web page support, and instead focuses on email client compatibility and campaign analytics.)
I have a small website developed using VS2005 and mySQl, it's just 2 webforms and login page.
During the development and testing phase, me and my customer were using IE6, and it was looking fine, we didn't test with other browsers because it's a small application, and just a add-in for large desktop application.
The customer informed me that site doesn't like the same when he installed IE7, for example I have a webfrom that show a page with Gridview that has multiply pages(AllowPaging=On), it doesn't look fine in IE7 and I can't navigate to other pages in Gridview, but it was working fine with IE6, and there's no complicated things, just plan GridView with small formatting.
I installed IE8 and doesn't look fine with it too, even in compatibility mood.
Have anyone faced the same problem?, and what should be the quickest or best solution for that?.
I know, I SHOULD NEVER USE WEBFORMS AGAIN.
The only reason for a difference in look between the browser versions is your styling and doctype.
Start with setting a doctype to run in quirks mode. You can get information about it here.
After that, see if things improve. If not, I would start ripping out any css/styles/themes you may be using. Then build it back up using normal CSS.
Incidentally, web forms isn't the problem in this case; it's a styling issue.
as Chris mentioned, add to that that browsers have really some annoying differences that makes you pull your hair sometimes, and 90 % of the time it is related to CSS.
so what i suggest is the following
use a tool called IE Tester, it is amazing tool that let you test your sites in all IE versions.
Use conditional command for targeting IE specific version if some CSS rule is wrong.
we use this tool http://rafael.adm.br/css_browser_selector/ it is really amazing it let you define css rules for each browser without hacking or conditional statement, but the down side it is Javascript dependent, but we had no complains.
also this script http://dean.edwards.name/IE7/ which is brilliant, it will let IE 6 behave like IE 7 which will save you tons of problems, again it is Java Script dependent.
Avoid Hacks as much as possible, the above methods will help you a lot.
hope this helps.
Short version: What is the cleanest and most maintainable technique for consistant presentation and AJAX function across all browsers used by both web developers and web developers' end-users?
IE 6, 7, 8
Firefox 2, 3
Safari
Google Chrome
Opera
Long version: I wrote a web app aimed at other web developers. I want my app to support the major web browsers (plus Google Chrome) in both presentation and AJAX behavior.
I began on Firefox/Firebug, then added conditional comments for a consistent styling under IE 6 and 7. Next, to my amazement, I discovered that jQuery does not behave identically in IE; so I changed my Javascript to be portable on FF and IE using conditionals and less pure jQuery.
Today, I started testing on Webkit and Google Chrome and discovered that, not only are the styles inconsistant with both FF and IE, but Javascript is not executing at all, probably due to a syntax or parse error. I expected some CSS work, but now I have more Javascript debugging to do! At this point, I want to step back and think before writing piles of special cases for all situations.
I am not looking for a silver bullet, just best practices to keep things as understandable and maintainable as possible. I prefer if this works with no server-side intelligence; however if there is a advantage to, for example, check the user-agent and then return different files to different browsers, that is fine if the total comprehensibility and maintainability of the web app is lower. Thank you all very much!
I am in a similar situation, working on a web app that is targeted at IT professionals, and required to support the same set of browsers, minus Opera.
Some general things I've learned so far:
Test often, in as many of your target browsers as you can. Make sure you have time for this in your development schedule.
Toolkits can get you part of the way to cross-browser support, but will eventually miss something on some browser. Plan some time for debugging and researching fixes for specific browsers.
If you need something that's not in a toolkit and can't find a free code snippet, invest some time to write utility functions that encapsulate the browser-dependent behavior.
Educate yourself about known browser bugs, so that you can steer your implementation around them.
A few more-specific things I've learned:
Use conditional code based on the user-agent only as a last resort, because different generations of the "same" browser may have different features. Instead, test for standards-compliant behavior first — e.g., if(node.addEventListener)..., then common non-standard functions — e.g., if(window.attachEvent)..., and then, if you must, look at the user-agent for a specific browser type & version number.
Knowing when the DOM is 'ready' for script access is different in just about every browser. A good toolkit will abstract this for you.
Event handlers are different in just about every browser. A good toolkit will abstract this for you.
Creating DOM elements, particularly form controls or elements with attributes, can be tricky with document.createElement and element.setAttribute. While not standard (and kinda yucky), using node.innerHTML with strings that contain bits of HTML seems to be more reliable across browser types. I have yet to find a toolkit that will let you use element.setAttribute to add a 'name' to a form element in IE.
CSS differences (and bugs) are just as important as JS differences.
The 'core' Javascript features (String, Date, RegExp, Array functions) seem to be pretty reliable and consistent across browsers, especially relative to the DOM/CSS/Window functions. There's some small joy in the fact that the language isn't entirely different on every platform. :-)
I haven't really run into any Chrome-specific JS bugs, but it's always one of the first browsers I test.
HTH
Chrome is actually a little different to Safari, it uses a completely different javascript implementation and problems have been reported with both prototype and jquery. I wouldn't worry about it too much for now, it's still an early beta version of the browser and such inconsistencies will probably be treated as bugs. Here's the bug report.
One "silver bullet" you may consider turning to is Google Web Toolkit (GWT).
I believe it supports all the browsers you are interested in, and gives you the ability to code your UI in a Java-compatible IDE such as Eclipse. The advantage of this is you can use IDE tools for code completion and compile-time error checking, which greatly improves development on large-scale UI projects.
If you use GWT UI components, it will hide a lot of browser-specific nastiness from having to be dealt with, but when you compile, will create a compact, deploy file for each browser platform. This way you never download any IE-specific code if you are viewing the app in Firefox. You will also have a client-side stub generated which will load the appropriate compiled bundle of JS. To sweeten the deal, these files are cacheable, so perceived performance is generally improved for returning visitors.
The landscape has evolved considerably to accommodate cross-browser development. jQuery, Prototype and other frameworks exist for cross-browser Javascript. CSS resets are good for starting on a common blank canvas for all browsers. BluePrint and 960 are both CSS frameworks to help with layouts using CSS grid layouts techniques that seems to be getting very popular these days.
As for other CSS quirks across the different browsers, there is no holy grail here and the only option is to test you website across different browsers and use this awesome resource and definitely join a mailing list to save up soem time.
If you are working on high volume production site then you can use a service like browsercam.com in the end game to ensure the site doesn't break horribly in some browser.
Lastly, don't try to make the site look the same in every browser. Your primary design should target IE/FF and you should be okay with reasonable compromises on others. Use the graded browser chart to narrow in on browser support.
As for best practices, starting using wireframes on blank paper or a service like Balsamiq mockups. I am still surprised how many developers start with an editor instead of a wireframe but then again I only switched a year back before realizing how big a time saver it is. Have clean seperation of layout (HTML), presentation (CSS) and behaviors (Javascript). There should be no styling elements in HTML, no presenation in Javascript (use .addClass('highlight') instead of .css({'background-color': 'red'});).
If you are not familiar with any of the bold terms in this post, Googling them should be fruitful for your web development career and productivity.
If you're starting from a base reset or framework and have accounted for IE and it's still all freaky, you may want to recheck the following:
Everything validates? CSS and HTML?
Any broken links to an included file (js, css, etc?). In Chrome/Safari, if your stylesheet link is busted, all of your links might end up red. (something to do with the default 404 styling I think)
Any odd requirements of your js plugins that you might be using? (does the css file have to come before the js file, like with jquery.thickbox?)
For UI, check out Ext.
It's great as a standalone library, though it can also be used with jQuery, YUI, Prototype and GWT.

I've found four things helpful in developing JavaScript applications:
Feature detection
Libraries
Iterative Development using Virtualization
JavaScript: The Definitive Guide, Douglas Crockford & John Resig
Feature Detection
Use reflection to ask if the browser supports the desired feature. If you want to know what event handling a browser supports, you can if(el.addEventHandler) for W3C compliance, if(el.attachEvent) for the IE-type, and finally fall back on el.['onSomeEvent'].
ONE BIG BUT!
Browsers sometimes lie about what features they support. I can't remember, but I ran into an issues where Firefox implemented a DOM feature, but would return false if you tested for that feature!
Libraries
Since you're already working with jQuery, I'll save the explanation. But if you're running into problems you may want to consider YUI for it's wonderful cross-browser compatibility. They even work together.
Iterative Development with Virtualization
Perhaps my best advice: Run all your test environment's at once. Get a Linux distro, Compiz Fusion and a bunch of RAM. Download a copy of either VMWare's VMWare Server or Sun's Virtual Box and install a few operating systems. Get images for Windows XP, Windows Vista and Mac OS X.
The basic idea is this: Compiz Fusion gives you 4 Desktops mapped onto a Cube. 1 of these desktops is your Linux computer, the next your Virtutual Windows XP box, the one after that Vista, the last Mac OS X. After writing some code, you alt-tab into virtual computer and check out your work. Plus it looks awesome.
JavaScript: The Definitive Guide, Douglas Crockford & John Resig
These three sources provide most of my information for JavaScript development. The Definitive guide is perhaps the best reference book for JavaScript.
Douglas Crockford is a JavaScript guru (I hate the word) at Yahoo. Lookup his series "Douglas Crockford Theory of the DOM", "Douglas Crockford Advanced JavaScript", "Douglas Crockford Theory of the Dom", and ""Douglas Crockford The Good Parts" on Yahoo! Videos.
John Resig (as you know) wrote jQuery. His website at ejohn.org contains a wealth of JavaScript information, and if you dig around on Google you'll find he's given a number of presentations on defensive JavaScript techniques.
... Good luck!
Just so you've got one less browser to worry about, Chrome uses the same rendering engine as Safari. So if it works in Safari, it should work exactly the same in Chrome.
See this post on Matt Cutts' blog.
Google Chrome uses WebKit for rendering, which is the same rendering engine as Apple’s Safari browser, so if your site is compatible with Safari it should work great in Chrome.
Update: Looks like this is now out-dated info. Please see Vox's comment on this answer.
If your very top priority is exactly consistent presentation on all the browsers listed with no disparities, you should probably be looking at AS3 and Flex.
Personally, I use Mootools as a simple lightweight javascript framework. It is simple to use and supports all the browsers above (except Chrome, but that seems to work too as far as I can tell).
Also, to ensure consistency across the browsers, I get a feature/style/behaviour/etc. to work in one browser first (usually Firefox 3 with firebug), then immediately check to make sure it works in all the other browsers (leaving IE6 for last). If it doesn't, I inveset the time to fix it right away, because otherwise I know I won't have time later (in my experience, getting things to work cross-browser takes about 50% of my dev. time ;-) )
Validating your javascript with a "good parts" + browser on JsLint.com makes it less likely to have JavaScripts behaving differently in FF, Safari etc.
Otherwise - using standards and validating your code as well as building on existing techniques like jQuery should make your site behave the same in all browsers except IE - and there's no magic recipe for IE - it's just bugs everywhere...
