Yup, you just read that.
My Googling gave me tons of results where people wanted a transparent background, and it appeared white.
Today, I stumbled upon the opposite ! It seems to be a real bug since I was able to reproduce it in a JSFiddle : http://jsfiddle.net/qtByH/
The background-color is set to red by default, and everything works fine. If you change it to white and re-run the fiddle (using IE7, of course), the background remains transparent when you hover the link.
Any thoughts ?
Edit : here is the code in case the fiddle vanishes away.
HTML :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
Test
</body>
</html>
CSS :
body { background-color: green; }
a:hover { background-color: red; }
Well, you have an HTML document inside another HTML document, which probably makes the browser revert to quirks mode. The JsFiddle site already adds a document around the HTML code, so you should not enter a complete HTML document.

Do you have a chroma filter somewhere?
filter: Chroma(color='#ffffff');
or
filter:progid:DXImageTransform.Microsoft.Chroma(color='#ffffff');
or something like that?
A chroma filter set's a color to be transparent.

As pointed out in my comment, zoom: 1; was the way to go (must have been yet another hasLayout issue).

Not sure if I'm doing something wrong here or whether this indeed is a Chrome rendering bug.
Here is my very small example:
.hover-test span {
opacity: 0;
transition-property: opacity;
transition-duration: 1000ms;
}
.hover-test:hover span {
opacity: 1;
}
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>TEST opacity</title>
<meta name="viewport" content="width=device-width,initial-scale=1"/>
<link href="styles.css" rel="stylesheet">
</head>
<body>
<button class="hover-test">hover me<span>hidden</span></button>
</body>
</html>
It works in all browsers I checked like expected.
It does work in Chrome as well, when I put the CSS in a style tag directly in the HTML file.
It does NOT work in Chrome (91.0.4472.101), when I put the CSS in a separate file and include it with a link tag.
With "not working" I mean, that on page load the span is shown and then faded out, without the mouse cursor being near the button.
Is this a Chrome bug, or am I doing something wrong here?
How can I achieve the desired behaviour in Chrome, which is: span is hidden on page load and only shown/hidden on hover?
It looks like it is a Chrome bug,as written here: https://www.hawkbydesign.com/weird-google-chrome-css-transition-on-load-bug/
Well, after making some further updates and refreshing the page, I noticed that the transition was firing on page load. What I mean by this is instead of being hidden on page load, as they should be, the elements were visible and would transition to their hidden state.
this is exactly the problem reported.
More:
The bug happens whenever you don’t have any script tags on the page, apparently. For whatever reason, this causes css transitions to trigger upon page load. While I was also digging, it appears that this happens sometimes with the form tag as well. What a weird bug!
The solution is to include a script tag in your page. Whenever I found the solution, they said to include a space in the script tag, but I found that it works fine even without the space.
I actually added jQuery on the page using the CDN link and the bug seems gone.
You appear to be bumping up against a timing problem.
Try this code with your styles file:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>TEST opacity</title>
<meta name="viewport" content="width=device-width,initial-scale=1"/>
<link href="style.css" rel="stylesheet">
<style>
</style>
</head>
<body>
<script>
function insert() {
document.body.innerHTML = '<button class="hover-test">hover me<span>hidden</span></button>';
}
window.onload = insert;
</script>
</body>
</html>
This waits for loading before putting the button in the document and on Chrome (and Edge) on Windows10 at least all is well.
Chrome/Edge seem to differ from say Firefox in whether loading is synchronous or not - or maybe it's just a lot faster writing the document.
Changing the font size with CSS is just not working in IE9. The font will change but the font size will not.
It works perfectly in chrome and firefox.
I tried to use em,pt instead of px. i tried font-size:40px. i tried everything.
The font size will just not change.
<!DOCTYPE html>
<html lang="en">
<head>
<title>test</title>
<meta charset="utf-8">
<style type="text/css">
body{
font: 40px Arial;
}
</style>
</head>
<body>
font size test
</body>
</html>
I think your CSS is overridden with you browser settings. Check the accessibility settings of the browser.
body {
font-size: 40px;
font-family: Arial;
}
If you have tested this with the exact document you posted, then apparently your IE 9 is broken. Re-install it. Otherwise, please post a complete example code or a URL that demonstrates the problem.
Make sure your zoom in IE9 is set to 100%. To do this, Hit CTRL + 0 while in the browser.
Make another CSS definition is not overriding your font-size statement. You can even force the font size by using the !important attribute like this:
body {
font-size: 40px !important;
}
Make sure you are clearing your cache when you refresh the page. To do a cache-free reload of a page, Hit CTRL + F5 in your browser. This will flush the cache and reload the page completely.
As far as the code you posted, I copy/pasted it as is and it works as intended in IE9. You may want to reinstall IE on your computer if you still can't get it working.
Have a look at this JSFiddle. I am trying to get this float layout working in IE7. Works in everything else. The two float rights should be next to each other. But in IE7 it messes up.
Any ideas on a fix? Thanks for you help.
http://jsfiddle.net/c9Wmx/4/
*updated fiddle
http://jsfiddle.net/c9Wmx/5/ <-- this works but is there any way to do this without using an empty div?
You can give width to your .page DIV. like this:
.page{
width:480px;
float:right;
}
See this updated fiddle: http://jsfiddle.net/c9Wmx/6/
if it only happens in IE you can try putting the following in the head html tags.
<meta http-equiv="X-UA-Compatible" content="IE=7" />
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
Are unused CSS images downloaded by the browser or ignored?
Eg. in CSS rules which don't match any elements.
.nothingHasThisClass{background:url(hugefile.png);}
Or would this be browser-dependant?
This would be browser dependent, since it's how they decide to implement the spec, however in a quick test here:
Chrome: Doesn't
FireFox: Doesn't
Safari: Doesn't
IE8: Doesn't
IE7: Doesn't
IE6: Unknown (Can someone test and comment?)
No, they are not downloaded, not at least in Firefox, IE8 and Chrome.
An easy way to test this:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.nonexistent {
background: url('index.php?foo');
}
</style>
</head>
<body>
<?php if(isset($_GET['foo'])) {
file_put_contents('test.txt', $_SERVER['HTTP_USER_AGENT']);
} ?>
</body>
</html>
If test.txt is populated with the browser's user agent, then the image is downloaded. This was not the case in any of my tests.
A quick test proved it.
<!DOCTYPE html>
<html>
<head>
<title></title>
<style type="text/css"><!--
.hasnothing{background-image:url(http://25.media.tumblr.com/tumblr_ky7aakqvH01qatluqo1_400.jpg);}
.hassomething{background-image:url(http://27.media.tumblr.com/tumblr_kxytwr7YzH1qajh4xo1_500.png);}
--></style>
</head><body>
<div class="hassomething"></div>
</body></html>
The 2nd image, tumblr_kxytwr7YzH1qajh4xo1_500.png, was downloaded but not the other one. This was proven true in Chrome (Developer tools) and Firefox (Firebug).
Firefox and Chrome (Ubuntu 9.10) don't download images for classes/ids that aren't applied in the DOM.
This may be both platform and browser dependant, though.
Sometimes, it depends just exactly what "unused" means. Different browsers define it differently. For example, in Firefox, styles applied to the <noscript> tag are deemed "unused" and thusly, any images won't be downloaded.
Chrome 26 (possibly all of them, not sure), does download CSS images if they are applied to the <noscript> element, even when JS is enabled. (It isn't immediately clear to me why though, perhaps this is a bug?).
It does not download CSS images applied to elements within the <noscript> element, though. (this is expected behaviour, of course).
Example:
CSS:
noscript { background-image: url('always.png') 0 0 repeat; }
noscript p ( background-image: url('nojsonly.png') 0 0 repeat; }
HTML:
<noscript>The CSS background image of this NOSCRIPT-element will always be downloaded in Chrome. Will not be downloaded in Firefox</noscript>
<noscript><p>The CSS background image of this P-element won't be downloaded in Chrome or other browsers, unless JS is disabled</p></noscript>
In this case, if the user has JS-enabled, both always.png and otherbg.png are downloaded in Chrome. If the user does not have JS enabled, then only nojsonly.png is downloaded in Chrome.
I use this technique for measuring traffic-levels from non-JS-enabled users, as Google Analytics fails us here. I prefer using the background CSS image rather than a normal <img...> tag, because I'm working under the (untested) theory that bots are less likely to grab a CSS image than a <img...> image, leaving more accurate counts for the human-visitors.
Almost all browsers do lazy-loading. If an image is not required, it does not download. Use firebug (add-on in Firefox/Chrome) to see load time for resources.
Interestingly, though, Chrome (at least) will download unused.png in the following example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<title>test</title>
<style type="text/css">
.unused {
background: url(unused.png) no-repeat;
}
.used {
background: url(used.png);
}
</style>
</head>
<body>
<div class="unused used">
hello world
</div>
</body>
</html>
I want to fit my website in IE .I want to know how i give the name of css selector in IE like firefox.Please help me!
i did'nt undersatnd your question "name of css selector in IE",but if you have to assign the css on selector p use like (<p>hello everyone</p>) this
p {
border:1px solid red;
font-size:24px;
}
always call your ie css file AFTER any other css so it overwrites any previous methods.
if you're still having problems, you can force a css definition to take priority with !important.
Without important, the div background would be blue, because that's the last declaration made
#mydiv{
background-color:green;
}
#mydiv{
background-color:blue;
}
now, using !important, you can force priority. the background will be green regardless of the order of declaration:
#mydiv{
background-color:green !important;
}
#mydiv{
background-color:blue;
}
if you're looking for css hacks for IE (not recommended, though sometimes essential), you can get more information from this excellent article.
hope this helps!
There is nothing wrong with the CSS code that you have shown so far, so repeating it in a style sheet specific for IE will not make any difference at all.
Generally you don't need a separate style sheet for IE. There are some rendering bugs in IE that you may have to circumvent, but that can almost always be done by tweaking the current CSS and HTML.
To find out what you need to do to make it work in IE, you should try to find the reasons for the differences. Most CSS is exactly the same, so if you don't see the effect in the page it's usually because the element is not where you think it is or doesn't have the size that you think it has. If for example the height of an element is zero, you will obviously not see it's background color.
First make sure that the page has a proper doctype, so that it doesn't render in quirks mode. This is important to make it work as close to the standards as possible in IE.
Open the error console in Firefox and view the page. It will tell you if you have any errors in the CSS code. There are standards for how to render correct code, but there is no standards for how to handle incorrect code, so if you have any errors you will get widely different results between browsers.
The plugin FireBug in Firefox is useful for seeing exactly which styles affect each element in the page, and you can even edit the CSS and see the result immediately. There is a similar tool built into IE 8 called Developer Tools. For IE 7 you can install Developer Toolbar that gives you some of this functionality. Each tool will allow you to select an element in the code and shows you exactly where it is on the page.
To fix your website in firefox and IE you can use the below methods.
Method 1:
You can use the "if condition" that you have used. You need to mention the version of IE in the if statement. See the code below
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Browser Detection Example</title>
<style type="text/css">
body{ background:blue}
</style>
<!--[if IE 6]> <!-- for ie 6 browser -->
<style type="text/css">
body{ background:red}
</style>
<![endif]-->
<!--[if IE 7]> <!-- for ie 7 browser -->
<style type="text/css">
body{ background:red}
</style>
<![endif]-->
</head>
<body>
</body>
</html>
Method 2:
You can use the css hack inside the css code itself. No need to use a separate css file. You can code in the same css. See the example below
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<style type="text/css">
body{ background:blue; _background:orange;}
</style>
</head>
<body>
</body>
</html>
Note : prefix "_" before the css code it will get render in ie6...
