We have a legacy application based on EXT-JS.
We like to add new module into the existing application, using AngularJS and bootsrap.
My problem is that bootstrap’s CSS are conflicting with CSS of the legacy code.
The new module, which written using bootstrap and AngularJS, wrapped around by legacy code, so I need to import exists CSS and new CSS on the same page.
I thought of 2 possible solutions:
Having a prefix to bootstrap’s css file and apply it only to inner part of the page content (AngularJS, new module). The problem is that popup, and angular-bootstrap 3rd party component still interrupted by legacy CSS.
Having my whole inner page (AngularJS module) in separate IFrame, embedded into page that contains the legacy CSS.
It seems like using IFrame solves my problem, but I aware that using IFrame is discouraged, and I am looking for optimal solution for my problem.
Do you think that IFrame is a good practice in this scenario?
Do you have other proven solution?
Planning to use iframes just to get around the css conflicts - not a very good idea. Though iframes can come handy in some cases mostly its usage has been abused just to get around some issues easily.
Do you think that IFrame is a good practice in this scenario?
No. The only issue here is the conflicting css styles between bs and extjs. And planning to use Iframe to get around this is really a bad choice. As you are using angularjs I feel using iframe may restrict its usage to some extent. For instance,embedding it in iframe I think the navigation back and forward buttons wont work as expected, in case your are planning to use angularjs routing. And when using Iframe it will be very hard to debug front end issues.
Do you have other proven solution?
Well I do not have a proven solution but you already have mentioned an idea which may work easily. Bootstrap can be customized to any extent you want to using less variables.
For instance for your issue just namespace the bootstrap styles using less.
.bs {
#import "less/bootstrap.less";
}
And don't get into the mindset using less/sass to compile css is complex. Once you get used to it, this will make this will make FE developement much easier than before.

I'm trying to reach the best css practice on my website using my own custom css till I found out I can use css framework such as bootstrap or foundation zurb instead. I thought using such framework directly without the need of making my own custom css is possible, but it turns out that all css frameworks are limited to some point yet I need to add extra custom css so my site look the way I want.
I want to use css framework because of the fact that it is being served over CDN so no extra bandwidth, and also for load speed and performance.
now my question, is it possible to be using only css framework on a website without the need of adding a custom css?
also how about creating my own custom css and using #import to a css framework inside the custom file, is that a good practice?
can anyone enlighten me to an efficient method serving a css file with/without css framework to my website?
You can use a plain framework without writing any custom CSS if you either a) Are happy with how it looks without custom CSS or b) like one of the many themes you can get for such frameworks.
You can #import a framework into your own custom CSS - in fact, many frameworks are available as less and importing them allows you to use variables from the framework in your own CSS as well.
As far as efficiency goes, are you sure this is the performance problem you have? If you haven't measured the performance, you aren't ready to optimise! It will, of course, be a straight economic trade-off between looking exactly as you want, and keeping the page load fast.
using a css framework is always a good option. You can use either bootstrap/foundation. along with the various functionalities on the site it would provide u the animation effects as well. And would help to complete the site faster as they provide the snippets of code. You can use less/sass and have the styling customized in the variables so you wont have to include extra custom css file.
I have already built a site using CSS. Now looking back I regret not taking the chance of using Bootstrap. My website is already built and styled. My questions is, is it possible to use bootstrap even though you already have styled you website without having to remove all the CSS?
Bootstrap uses a set of pre-configured classes to implement it's styling rules..
So unless you somehow incorporated the same class names in your site and intended the same styling as was intended by the Bootstrap developers, you are going to have to make the necessary changes on your own.
That said, if your project is intended to be extended in the future, it may still be a good idea do re-work what you did up until now with Bootstrap, in order to save time in the future (I am assuming that the project is not very large in scope).
There are few things you need to know:
Bootstrap uses box-sizing: content-box so if you are not, it will probably impact all your padding/border stuff.
Bootstrap comes with a reset and few helpers with generic names that can interfere with your own style.
That said it's totally ok to add bootstrap to your project and it should be smooth.
I am using insert-CSS node module for adding styles to DOM, internally this adds the embedded approach.
so far my understanding is using external style sheets is best way to do it. But while using insert CSS, css added to the js bundle and dynamically css embedded to the . so this also looks as same using external CSS.. and css will be cached with js and there will be one file(js+css) we can avoid one http request for loading CSS ?
I feel this insert-css is better than traditional approach(external css) am i correct? please suggest me your thought on the same and add some docs to refer.
so my question is which is the best approach among using "insert-css npm" or "external css"
I didn't find useful info on this question and sharing my experience.
My personal recommendation is not to use "insert-css" modules for the simple projects like dealing with forms and minimal amount of components.
"insert-css" - as mentioned above, "insert-css" add the embedded styles, in the network, its passed as base64 format. Though it's less weight in the network, browser needs to convert the base64 format to css and adds the embedded css, this conversion process will happen allays in js side, I guess which will cause the performance issues
After many fruitless days of trying to get JQuery Mobile and AngularJS routing to work together, I'm considering my alternative options..
Is there a way to use the JQM CSS without relying on JQuery's javascript?
Or is there a substitute CSS package that are recommended? something with all header/footers and lists that is available in JQM?
Of course, there is an CSS file in the package you downloaded. But all the sites functionality and the mobile adaption will be broken. You can rename the classes and the id's or directly use the classes from the css file.
Greets
There are quite a few jQueryMobile functionalities that rely solely on the CSS fole, eg. the grids. You won't get the interactions, but all the buttons looks, shapes and colors are totally useful without the JS.
Still - depends on your expectations.
And when using it like that you need to understand a bit how JQM works to know the classes and html structure that's expected, because some of these are generated by javascript.
[kind of digression]
But maybe you just dislike how big jquerymobile is?
Then you probably want to use: http://jquerymobile.com/download-builder/ to get only stuff you need, and also use tte themeroller here: http://jquerymobile.com/themeroller/index.php to create only one theme (global) and remove other themes (A,B,C)
That's how you get it a lot smaller.
You can reuse the CSS file inside he downloaded JQM package. The file jquery.mobile-1.x.x.css can be included, but make sure to include the images folder as well and have it at the same location at the destination.
If you aren't sure of which classes to include for which purpose, you can simply find it out by inspecting a JQM demo page to find out (View source will not work due to the JQM javascript).
JQS provides support for ui animations and user experience enhancement. Removing libraries will dispart you from accessing css contents created and used by javascript in order to 'manage' a front-end design. –
Yes you can use jquery mobile theme and adapt it to your needs.
Just reading there was adapter releases for your situation : https://groups.google.com/forum/?fromgroups#!topic/angular/oIxRxpkn3L0
Perhaps substitutes to css packages are documented. About heavier JQM templating and using, there are some introduction to what you'll need to take a look at like adobe theme-control-jquery-mobile.html ..
I am building a new WebSite based on Grails technology.
Concerning the graphical design of my website, I plan to use services from a professional web designer but meanwhile, I need to do some basics graphical design myself in order to have a "user-friendly" beta-version.
I have read through the stackoverflow.com site but couldn't make up my mind. Here is what I have found out:
how-do-you-choose-a-css-framework
what-is-the-best-css-grid-framework
can-someone-recommend-a-bells-and-whistles-css-framework
what-is-the-best-css-framework-and-are-they-worth-the-effort
But unfortunately there are many contradictory answers.
First, some say that using CSS framework is backwards authoring and not a good thing. Others advice YUI Grids, BluePrint, 960 gs, YAML...And many say that Compass allows to develop CSS layouts easily and reusable.
So considering that:
I am new to the CSS world and I do not intend to be a web designer
My layout should be user-friendly (but not necessary awesome L&F)
It should be maintanable and easily improvable (by a professionnal web designer)
Easy to implement (in order to have something quickly)
What do you advice me for getting started with the web design of my site?
Thank you for your advices.
Fabien
First, if you don't intend to be a web designer, I'd suggest outsourcing your CSS. There are several websites where you can supply HTML or a Photoshop design and have it coded up for well under a grand (1k). Or get HTML/CSS designs free.
Then there is one thing you need to know and another two you need to work out:
all HTML should be written in a semantic and valid manner: semantic = properly ordered headings, lists, no excessive divs etc.; valid = will pass WC3 validation tests. None of this is rocket science, but is still a skill that needs to be learned. Andy Clarke's Transcending CSS is a great book on semantic HTML/CSS. For ease of maintenance, the HTML and CSS should be tidy and consistently indented, etc.
you need to determine whether you'll be needing an admin backend and database for managing content, or if you're just building a site consisting of static pages (i.e. html and css files, images and other media etc.). If it's the former, that's a whole other learning curve :-)
what are your best skills? If you're a good designer, get other people to write the HTML/CSS, or use a ready-made template (there are many on the web) and customise it. Here's a good start for multi-column layouts. If you're a programmer, learn to use a framework like Django (Python), Titanium (Perl), something smaller in Ruby (because Ruby on Rails is a bit big to start with) or one in your favourite language.
Good CSS is a craft, and simplicity is the essence, but if you want to learn enough to get started, my advice would be to:
understand inheritance (the 'cascade' in CSS) and the fact that anything can be a 'block', so don't use lots of nested divs just to apply a style. Instead, apply the style to the HTML element itself, or to the element only when it appears in a parent block (like a menu unordered list contained in a sidebar div);
learn about block and inline elements (Web Design from Scratch is a great learning resource and I'd recommend it), and that CSS can change this behaviour;
test in Firefox, then test in Internet Explorer. >= IE7's not so bad (but look out for HasLayout). What you can't tweak to get right in IE, use conditional comments to add CSS that only IE can see - never use CSS hacks - .htc files that add missing IE functionality (e.g. rollover styles on any element) are available;
learn about CSS positioning, and use 'fixed' sparingly;
put all your CSS in one file (for starters), and don't use inline CSS in the HTML;
styling forms and form fields is almost a separate skill :-)
Use background images to add style, but also understand that you can offset and overlap images using positioning. You'll need to use PNGs for nice transparency, though. Oh yes, and opacity looks nice, but requires non-standard CSS for now. although the more flexible rgba (a=alpha) method is widely-supported. As do rounded corners, but both worth using.
I'd avoid CSS frameworks and resets for now - they'll complicate things at this stage by adding yet another DSL to learn (but read the arguments and the pros and cons). To avoid annoying default margins and padding, I always reset everything by doing html *, body * {margin: 0; padding 0;} then build padding and margins back in wherever needed - never been a problem so far :-)
What do you advice me for getting started with the web design of my site?
Get Firebug plugin for Firefox now!
Primary CSS uses:
See which CSS rules apply
Change CSS in real time and see the affect
Inspect other websites to see how they do things
I would not be able to develop CSS (and other web related technologies) without this tool
Take a look at YUI CSS reset/base/font/grid
http://developer.yahoo.com/yui/3/cssreset/
And Grid 960 also has some nice layouts (search for their site in google)
I don't know what OS you are running, but if you are a Mac user, I suggest a great free tool for CSS: Xyle Scope. It's not an editor but a CSS viewer/scanner, it let you browse easily the CSS code of any web page so you can learn better how css works and you can analyze any well done layout on the web.
CSSEdit (Mac Only) is a good solution for writing Cascade sheets, easy to use, not expensive, and reach of features.
Fireworks: I think is a great software to draft your layouts and make some good graphical works!
Dreamweaver: it's an all in one solution for web developing ... it's a really great tool to easily maintain synched your remote version of the website with your local one.
Coda (Mac Only) is a very good alternative to Dreamweaver, even if it don't let you manage and edit the .htaccess files!
For coding your web site I suggest dreamweaver or Coda, but an other good alternative is BBEdit (Mac Only).
Bootstrap, Its the best css framework i can suggest, there is another one called foundation also but i prefer bootstrap more since it is popular among developers and is extendible. There are few more other frameworks, I wrote a blog about that, Here Read it too if you want http://www.andwecode.com/freebies/5-responsive-css-frameworks :)
