I have set some style for h2 tags (color, font-size, etc.), but when I put "A" tag inside, then style becomes as link. My html:
<h2>
<a class="no-decor" href="http://localhost/xxx/">Link</a>
</h2>
So, as You can see, I've created "no-decor" class. It should inherit h2's style for "a" tag.
a.no-decor {
color:inherit;
font-family:inherit;
font-size:inherit;
font-weight:inherit;
text-decoration:inherit;
}
On Firefox everythig is ok, but IE still shows tag "a" style (underline text-decoration and blue color). I know, I can set some style for "h2 a", but maybe somehow it is possible to force work CSS inherit values on IE7?
P.S. On IE6 doesn't supports too.
P.P.S. There is some example in same way: http://www.brunildo.org/test/inherit.html
No, IE has never supported inherit for any property - sorry. This has been fixed in >= IE8.
Whilst you could use a JavaScript fix to copy the properties from h2 to a, it's probably easiest just to apply the same styling rule to both elements:
h2, h2 a {
font: something;
color: black;
text-decoration: none;
}
You don't need to set inherit on text-decoration anyway, because decoration doesn't inherit from a parent into a child: the underline effect is on the parent and goes through the child; the child cannot remove it (modulo IE bugs). 'text-decoration: none' on the child is the right thing, unless you want potentially two underlines...
try
a.no-decor{
color:inherit;
//color:expression(this.parentNode.currentStyle['color']);
text-decoration:none;
}
That'll get rid of your blue color and the underline. You could use a similar expression for the underline, but you'd be better off just using text-decoration:none since that's all an inherited text-decoration is gonna give you anyhow and no need to use expressions when not absolutely necessary (you'll take a performance hit when using expressions).
A bug's a bug and there's nothing much you can do, short of workarounds.
There's a test for inherit support here.
You can also try to use a script like ie7-js, which "is a JavaScript library to make Microsoft Internet Explorer behave like a standards-compliant browser"
Internet Explorer <= 7 versions don’t support the value inherit for any properties other than direction and visibility.

I've the following problem, I'm trying to change the color of the text of a "< li>" element, in joomla menu. I give the menu a link to css selector called blueMenu, this is my CSS regarding the class:
.blueColor {
color: blue;
}
However this doesn't change the color of the text, on the other hand if I change "color" with "background-color" the background of the text becoms blue. Any idea what may causing the problem?
You dont give much information, but it might be that the li has a child element inside that its overwriting the li styling, make sure you using the style on the last child.
You can also force it with !important;
.blueColor {
color: blue!important;
}
This really much depends on your template.
As already said, reasons can be inline-styles, or may more "distinct" declarations.
If you just specify the class like you did in .blueColor this will be treated with a lower priority as e.g. li.blueColor or to get even more clear both with be treated with a lower priority as e.h. #someId.andClass .subElementClass li.blueColor a.thisIsWhatIsReallyBlue
This is more about CSS specifications than a Joomla-Problem though.
You might check the style that is really applied by just launching your Development-Tools of your webbrowser (for Chrome simply press F12 or right-click on the element and inspect the element directly)
The CSS-Section on the right side might tell you about what really makes the item become blue ;)
Oh, and just a note:
As already mentioned you can use !important to "force" the styles to be applied, but if this is not absolutely necessary, i'd suggest to find the way to override this style on a clean way, since !important, if used to often, might result in a complete mess of your stylesheet.

I'm not familiar with joomla but it may be inserting an inline style to whatever element you're trying to style. Right click on the element and use inspect element (firefox) or just inspect (chrome) to see if any styles were applied.
It'll look like <div class="" style="color: blue;">
I have code like this:
.module::first-letter{
visibility:hidden;
}
But this solution is not working on Firefox:(
Display:none; not working with "::first-letter" CSS code :(
How can I hide first letter in Firefox?
you can always try setting font-size:0 while this is not fully supported.
.module::first-letter{
font-size:0
}
<div class="module">Hide Letter H </div>
or as last resort color:transparent
.module::first-letter {
color: transparent
}
<div class="module">Hide Letter H</div>
Note the difference between both, 1st removes the letter space, second
one doesn't.
Note: The following properties can be used with ::first-letter:
font properties
color properties
background properties
margin properties
padding properties
border properties
text-decoration
vertical-align (only if float is 'none')
text-transform
line-height
float
clear
http://www.w3schools.com/cssref/sel_firstletter.asp
Another note, it only works with block level elements, I am not sure, and I could be wrong, you can hide the first letter with only CSS. Quite easy in JS to pull off.
As mentioned in the other answers the properties that can are used is limited but it's possible other browser vendors are initiating greater support
As this list will be extended in the future, it is recommended that you not use any other properties inside the declaration block, in order to keep the CSS future-proof.

Is there any reason why this does not work on Internet Explorer or Chrome:
<html>
<head>
<style>
A {font-weight: bold; color:black;}
A:visited {font-weight: normal; color: black; }
.Empty {font-weight: bold; color: black; }
</style>
</head>
<body>
click me
</body>
</html>
The link I click never goes to normal and just stays bold. On some other browsers it works.
Changing case did not affect it. Changing a to a:link did not affect it. Changing color works, just not font-weight.
One workaround was to change accessibility to ignore web colors. I do not have access to the source, so I had to do it this way.
Actually, this has nothing to do with case sensitivity. This is a security feature. The functionality of :visited pseudoclass has been restricted in many modern browsers (Fx4, IE9, Chrome) to prevent CSS exploit: read about it here.
Nowadays, getComputedStyle() in these browsers usually returns values for visited links as if they weren't visited. However, I can simply imagine circumventing of that: using font-weight for visited links, the element's width changes so browsers that would allow changing font-weight for :visited links wouldn't actually fix the security hole.
You can see there are some specific things browsers do to protect against this:
The window.getComputedStyle method, and similar functions such as element.querySelector, will always return values indicating that a user has never visited any of the links on a page.
If you use a sibling selector such as :visited + span, the adjacent element (span in this example) will be styled as if the link were unvisited.
In rare scenarios, if you're using nested link elements and the element being matched is different from the link whose presence in history is being tested, the element will be rendered as if the link were unvisited, as well.
Thus, there's no workaround for this issue.
One useful attribute that does work with :visited is background-color. So try:
:visited {background-color:red;}
:visited also works on non-a elements.
The problem has to do with history sniffing, changing css properties is disabled for visited links due to privacy issues.
I came up with the following workaround to reach the desired effect.
It is possible to change the background-color of the visited link.
The solution is very simple:
set a background-image on the link with the same height as your link
and 1px width and repeat the image horizontally
the image has the same color as the background of the link
make one pixel of that image transparent, in the vertical middle
on :visited state just change the backgroundcolor of that link to the text-color of the link
Only one line of the background-color wil be visible, because the background-image is masking it
Here's an example:
a:link {
color:#000;
background:#FFF url('../img/linethrough.png') repeat-x top left;
}
a:visited {
background-color:#000;
color:#000;
}
CSS itself is not case-sensitive, but if the HTML file using this style has an XML declaration and an XHTML doctype, that CSS is not going to work, because tags are case-sensitive. You'll have to set the "a" tags to lower-case.
Explained here:
http://reference.sitepoint.com/css/casesensitivity
Perhaps try changing the color attribute and see whether that has an effect at all.
To troubleshoot, you might want to try to utilize the developer tools in chrome to see what style is applied.
You need to have separate declarations for a:link, a:visited, a:active, etc.
Remove your first style that does not contain a colon. It's overriding. Replace with a:link.
I've just learned how to make a text to blink (<div style="text-decoration:blink">text</div>).
How about the other decoration modes such as color changing? Are they available in CSS?
Thanks.
Nothing too interesting with text-decoration. A good resource is always the w3:
http://www.w3schools.com/Css/pr_text_text-decoration.asp
h1 {text-decoration:overline}
h2 {text-decoration:line-through}
h3 {text-decoration:underline}
h4 {text-decoration:blink}
Regarding your second question - of course. CSS can (and should) be used to style almost anything, though blinking text is an extreme example, most rules are much more useful.
Yes, color changing is available in CSS. Use
<div style="color:red">foo</div>
for example. You probably want to check out a good CSS introduction or the official standard:
http://www.w3schools.com/css/css_text.asp
http://www.w3.org/TR/CSS2/
The available text-decoration values are:
blink
line-through
none
overline
underline
See http://reference.sitepoint.com/css/text-decoration for more details.
Yes, you can use the following:
color: #FFFFFF; (which would make your text white in color)
font-weight:bold;
text-decoration:underline;
etc.
You should really Google this.
I suppose that by color changing you don’t mean just to set the text color as color does but more complex animations.
There are some experiments like WebKit’s -webkit-animation, -webkit-transform or -webkit-transition. But those properties are proprietary.
Nowadays such effects are done with the help of JavaScript. There are plenty JavaScript frameworks you can use like jQuery, mootools, Prototype, Script.aculo.us, etc.
No, these are generally programmed using JavaScript.
If you are referring to link color changing on hover, that is done with css.
a:link { color: blue; }
a:hover { color: green; }
There are four currently-supported text decorations. (Blink is no longer supported in most browsers.)
Draws a line over the text
h1 {text-decoration:overline;}
Draws a line under the text
h1 {text-decoration:underline;}
Strike through. (Draws a line through the text.)
h1 {text-decoration:line-through;}
No decoration.
h1 {text-decoration:none;}
NEVER USE BLINK, it has little browser support, it is useless, and has severe accessibility issues. It was made as a proprietary attribute during the browser wars between IE and Netscape, and most browsers never supported it, IE, who copied it from Netscape, has deprecated it, and Netscape, has been dead for almost 6 years.
(Feel free to correct my little history lesson.)
CSS text-decoration property is used to decorate the text or remove the decoration for the text. CSS text-decoration property is mostly used to set or remove the underlines on the web page.
In many case, when you wish to have no decoration for the text you can simply say text-decoration: none;. That makes the text have no decoration.
See the below example for more understanding
h1 {
text-decoration: overline;
}
h2 {
text-decoration: line-through;
}
h3 {
text-decoration: underline;
}

Here is my code:
.blue {
color:#6E99E1;
font-size:9px;
}
<span class="blue">::CLICK HERE:: to view our New Equipment inventory. <br /><br /></span>
I've somehow triggered something that prevented the <a> tag from inheriting color of parent <span>.
Just an addendum to the other responses, if you want your <a> tags to inherit the colour from their parent you can use
a {color: inherit; }
By default an anchor tag does not inherit attributes like color if an href attribute is present.
Check out the difference between these two on a page:
<span style=color:green>test</span>
<span style=color:green><a>test</a></span>
The following link is to the w3 c:
http://www.w3.org/TR/html401/struct/links.html#h-12.2
User agents generally render links in
such a way as to make them obvious to
users (underlining, reverse video,
etc.). The exact rendering depends on
the user agent. Rendering may vary
according to whether the user has
already visited the link or not.
.....
Usually, the contents of A are not
rendered in any special way when A
defines an anchor only.
This is an answer to the question as well as a reply to Kevin's answer and its comments.
Anchor tags do inherit color, linked or not. The only reason they don't in practice is because they already have their color set in the browser's default stylesheet. The same can be said for the underlining of the link (which, I presume, you didn't notice, because you actually want it or had already changed it yourself).
In Firefox, you can see this in Firebug if you toggle "Show User Agent CSS" (or you can have a look at Firefox's internal stylesheets directly. You can see the browser's defaults in Webkit's Web Inspector and Opera's Dragonfly as well. I don't think you can in IE.
I don't know of any site which has an overview of all browser's defaults. CSS2's "informative" HTML4 stylesheet as well as the YUI reset stylesheet would be a good starting point, but neither of them mention any (link) colors (the HTML4 stylesheet does mention the underline).
To find out which properties are inherited in general, you can use the CSS2 reference property index table (see the "Inherited?" column). SitePoint also mentions it in its CSS reference.
So if you want to make sure your link inherits its color from its parent instead of from the browser's default stylesheet, you would ideally do something like this:
.blue a:link {
color: inherit;
}
You could set it for the different pseudo-classes separately (so :visited, :hover and :active as well), or for the a tag altogether.
However, IE6 and IE7 don't support the inherit keyword, so if you want to support them too, you'd have to set the color explicitly.
I think a doesn't inherit color by default. (certainly it has always worked that way on my sites). Why not change
.blue {
color:#6E99E1;
font-size:9px;
}
to
.blue, .blue a{
color:#6E99E1;
font-size:9px;
}
Firebug will show you exactly which style rules are applied to which elements. It's perfect for this.
(A non-CSS possibility: Do you have link/alink/vlink attributes on your <body> tag?)
Edit: Duh, silly me, the others have it right - <a href> doesn't inherit colour. But Firebug is still a good tool for this kind of problem (even if I'm not. 8-)
In addition to firebug (which should be your first port of call), the IE developer toolbar will also tell you where a given style is sourced from, just in case IE - shock, horror - should be different.
You need to explicitly set the color of the links to override the default blue color.
You are likely seeing the a:visited colouring. Try this:
.blue, .blue:link, .blue:visited {
color:#6E99E1;
font-size:9px;
}
