If you visit this website http://inelmo.com/inelmo and click on one of the comments links under each article it expands a div which contains a facebook comments plugin. I don't know why, but there is a huge space after it, I am pretty confident it has nothing to do with my styling (although I might be wrong).
The markup for that bit looks like this:
<div id="cmbx(id of the article)" class="comentBox" style="display: none; width: 520px;"> // This is the div that hides facebook comments.
<div class="fb-comments" data-href="inelmo.com/story.php?id=(id of the article)" data-num-posts="5" data-width="520"></div>
</div>
I have no idea about what is causing that space under facebook plugin. Can anyone suggest any fixes?
jQuery used for slide:
function toggleSlideBox(x){if($('#'+x).is(":hidden")){$(".comentBox").slideUp(200);$('#'+x).slideDown(200)}else{$('#'+x).slideUp(200)}}
EDIT: I tested it in several browsers, some e.g. Firefox do not have any issues, but google chrome for example has.
I don't think your problem is related to your CSS or the Facebook comment box directly, although it seems to be the comment box that is causing problems to begin with. The actual problem seems to be with the jQuery slide function, which would definitely be hard to debug because the problem at first glance seems to be with the css or fb-comments.
Check out this post, it should be of some help to you. http://goo.gl/ZaduP
The post talks about a very similar issue that seems to be caused by jquery slide not knowing in advance what the height of the div is going to be. HTH

I'm implementing a dark theme on my website using tailwind classes. For example:
<tr className="bg-white dark:bg-dark-blue text-left dark:text-white transition-colors duration-300"></>
And for some reason, whenever I change my theme the transition isn't smooth but laggy and stuttering. I've noticed that with the increase of dark-styled elements on the page, the lag has gotten worse.
I'm not sure if this is actually a tailwind problem or a general CSS performance problem in the browser.
UPDATE
After some test I've come to the conclusion that it actually has nothing to do with transitions but with CSS itself.
I have a lot of elements on the page with dark classes set initially and then whenever I change the theme I just add/remove 'dark' class in <html>. I have may be 50 elements on the page which change their text color and background color and all of them are laggy whenever the theme gets changed. The lag is similar to when you have a memory leak or a loop. It stutters then loads all at once and stuff like that.
So I guess my question is how to optimize CSS performance in this case? or overall?
UPDATE 2
According to Performance page in devtools I'm dropping a lot of frames when changing the theme. And it actually feels like I'm getting 5fps. Here is a screenshot of Performance page prnt.sc/Zz6T88ZFs6Fp. I'm not sure how to read it, may be somebody can give some useful info
If anyone has ever faced/solved this problem, I'd greatly appreciate your advice
It may have to do with the critical rendering path. I'd advice you to read this excellent article : Achieving 60 FPS Animations with CSS3.
In a nutshell, if you have css transitions set other than on transform and opacity css properties, your browser has to recalculate the whole layout, which causes stuttering.
I don't use tailwind and it's hard to test my response without example code but I had a very similar problem several years ago when browsers were a little dumb.
I had many classes for color throughout the html and toggled them with jquery. Here's a quick example of how...
$(".red").removeClass("red").addClass("blue");
I determined that, at the time, the problem was that the items were causing repainting for each change.
What I ended up doing was swapping a class on the body:
<body class="blue">
Whatever
Something else
<!-- lots more -->
</body>
And then:
body.blue a {
color: blue;
}
body.red a {
color: red;
}
And that worked beautifully because, as I understood it, the repaint happened all at once... but I'm guessing to even try you'd have to write a lot of stuff on your own instead of using tailwind. Maybe not, so I hope this line of thinking helps even if using tailwind.
Edit: if I had the same problem and couldn't fix it quickly enough I'd fade the body with a quick opacity out and then back in. Complete hack but it might look cool. Not a solution to your real problem but it might help if you can't fix it.
You can go in the dev tools and then go under "network", then you click on "Disable cache".
After a lot of research I've managed to finally find some useful info.
With the help of this article and some info from here I found out that dropping frames is actually not uncommon but usually it is not as intense as in my case.
There are some particular lines in Profile.json (download from Network page), which can help you find the actual reason(s) of dropped frames. Look for unsupportedProperties.
In my case it was {"args":{"data":{"compositeFailed":8224,"unsupportedProperties":["color"]}},"cat":"blink.animations,devtools.timeline,benchmark,rail","id2":{"local":"0x76c803503df8"},"name":"Animation","ph":"n","pid":40040,"scope":"blink.animations,devtools.timeline,benchmark,rail","tid":13280,"ts":166257565931}. For me the reason was that too many elements on the page change their text color. 884 lines of compositeFailed related to 'color' for one theme switch on my page. Only refactor with the help of https://csstriggers.com/ would be effective in my case.
Currently, I don't know actual reasons for compositeFailed apart from that it has to do with color property and blink animation. Any Google devs would be welcome to enlighten me because I can't really find any info about that.
After spending a while creating an online portfolio, then uploading it, I noticed an issue with one of my sections. On the "Advertisement" section, I noticed it was not displaying the information, just the title. So, I kept on re-pushing the stylesheet.css, even editing it, and it would still look the same. The HTML, CSS, and JS is working how I wrote it. But it is just the section that is not showing. After browsing online and on stackoverflow for an answer, I believe it has to do with Firefox. When using Firebug, I noticed the section's background has been removed, causing the entire section to "disappear." It works just fine on Chrome. I'm not worried about IE, I know that browser has some issues in itself. Anyway, would anyone on here have an idea to resolve this issue, if I can? Or even, what could be causing this issue?
Here is my website to see for yourselves. www.voelkerdesigner.com

It is the opposite for me your entire site works in firefox for me but not in chrome, looking through your code, its being caused by your naming conventions. Namely #advertise
I use the adguard extension in chrome and below is the css it plugs into my html pages to hide ads, so im guessing your using an adblocker in firefox
#adsense_top, #adsensewide, #adspace, #adspace_top, #adspot-300x250-pos-1, #adspot-300x250-pos-2, #adswidget1-quick-adsense, #adswidget2-quick-adsense, #adtext, #adtop, #adv-masthead, #adv-top, #advert1, #advert2, #advertbox3, #advertise, #advertisement1, #advertisetop, #advertising-container, #advertising_wrapper {
display: none!important;
}
Might as well post a random answer on this... As i wont visit posted links by new users.. i'm just gonna guess that your background image might not be 100%...
In general i use background-image instead of background.. Short hand can be a little pain and breaks in some browsers if not perfect.
so i would compare against the following example
background-image:url('images/mybg.jpg');
background-image:url('http://somesite.com/images/mybg.jpg');
Basically alot of people do not use the url and just go straight for a file name or dont quote it.. And have seen that be the problem in the past, so do use the url('') method.
Otherwise if it still fails to work and you know the image is absolute, you would then have some other css that is either over riding your elements background or is preventing it from loading.
Another trick is using your console / inspect element to manually inject the background-image and see if that works... So once the page has loaded in chrome, inspect the element as normal.. And double click on your css property listing as you can add your own styles this way and if it fails, then its not the markup but something else.
I am having problems with my webpage. On all browsers the div aligns perfectly. However, on all versions of Internet Explorer the Div shows out of line. Here is an image of the difference:

I would really love the help, IE has done this to me several times. I would love to learn what to do in these types of situations. I read somewhere about an IE specific CSS file that would fix this but I did not fully understand what needed to be changed in this new CSS file. All help appreciated.

Try fixing the issues presented by the W3 validator. http://validator.w3.org/check?uri=http%3A%2F%2Fkynikosdesign.com%2Fcontact.php&charset=%28detect+automatically%29&doctype=Inline&group=0&verbose=1
You can add this and it should work (at least it did just through in-browser modifications)
after your normal css
<!--[if IE]>
<style type="text/css">
#mainbox{padding-left:0;}
#servicesright{float:left;}
</style>
<![endif]-->
That aside, you're also missing some closing tags it would seem and probably the reason for the weirdness.
Issues I detected on your page structure so far (which are causing the display issue):
#main-container should not have width
you are using table for your form layout which is a big mistake (it's pushing the whole content together down)
as a workaround removing width in (1) and width=100% in (2) will fix your problem butI highly recommend to follow good practices for your page layout. (i.e. using div instead of table).
The problem is on my site:

I've been wracking my brain trying to figure how to solve this. Basically, I wanted to create a "Featured Posts" slider by using EasySlider 1.7 . The slider is the first thing you see when on the site.
Everything seemed to be going well during the install, but once I finished I realized the nextText and prevText was showing on top of my background images. This seems to be a property that can't be modified with css or html as I think it's embedded in the javascript provided.
I tried the Best Answer found in this question ("CSS text replace with image, need hyperlink") and it worked for the nextBtn but when I tried it for the prevBtn the nextBtn disappeared and was replaced by the default setting. If anyone can explain to me how to properly use this method with both buttons, then that solution would be fine.
But if you can't then please help me come up with any other solution. I'm not very well versed with CSS or HTML, so I'm learning as I go right now. It's probably some dumb mistake I made, but I'd still like to know how to fix it!
Thank you in advance to anyone who responds!!
I tested it with firebug directly on Your page. Try this:
#nextBtn a, #prevBtn a {
display: block !important;
text-indent: -9999px;
}
Important is this !important ;) It makes that this display: block is more important than display: inline which adds Your slider plugin.
Not quite sure what's going on, but if you go to https://sites.google.com/site/shawnhasinger/files/easySlider1.7.js where you have linked it from, you get a log in page, meaning that it doesn't work! This isn't the issue you are facing, probably because you are logged in...
I have been working on a webpage. It is the first I have actually tried to design using an image and then use proper CSS layout rather than tables.
http://www.roccocammisola.com/proj/brunel/bgimage.html
I have been having issues with the shadows on either side of the main content area. Of course these are only an issue in IE. As you can see the shadow has been cut down to about 10% of its actual height.
With my relative inexperience how do I look for relevant fixes to this issue.
Any help would be very much appreciated.
FireBug, the most crucial tool for debugging CSS, amongst other things.
get it here
IE Web Developer Toolbar
It's not as good as firebug in general, but it helps when you have an IE-specific problem.
In addition to Firebug, making sure your HTML is valid is an invaluable tool and can minimize CSS headaches. Sometimes your CSS may not work right because there are mistakes in the HTML. The different browsers have different ways of dealing with improperly written HTML which can sometimes make it seem like there's a cross-browser CSS issue. The validator can help you find mistakes in your markup.
http://validator.w3.org/
+1 for FireBug
In this particular case, I'd just suggest a new approach for your shadows. Currently, you have them as items. You typically want to use CSS background images for things like this.
.mainShadowRight {
*/ your other stuff */
url('images/mainShadowRight.gif');
}
Your .mainShadowRight CSS class specifies a min-height (which IE6 doesn't understand, and IE7 doesn't always 100% get correctly)
and as DLarsen pointed out, it appears you are missing the background-image: url(); bit.
Thanks for all your answers, seems to have done the trick.
I think I spazzed out with the upload as I should definitley have had the bg-image stuff there.
That IE web developer toolbar looks pretty good too as I have firebug and web developer bar for FF.
Another hot recommendation for debugging CSS - CSS Viewer.
It's a Firefox add-on that allows you to hover over elements in a web page and see their exact style. Often you figure out that the final style was not what you meant, possibly due to some inheritance of styles.
