Learn CSS, Selectors, part 2 - Specific-Value Attribute Selector
(Page 3 of 7 )
You can apply certain styling rules if the attribute of the element has a specific value. This can be very useful. The syntax is similar to the attribute selector, but you need to include the specific value in quotes, as we will see in the following example.
Here's the CSS code:
a[href="http://www.w3.org"]
{
background-color: black;
color: white;
text-decoration: none;
font-size: 1.1em;
font-family: Tahoma;
}
Here's the HTML code:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<link rel="stylesheet" href="Selectors.css" type="text/css">
<title>CSS Selectors</title>
</head>
<body>
<p>You can use CSS with markup languages like HTML, XHTML and XML. All
those markup languages and also CSS has Specifications as the <a
href="http://www.w3.org">W3C website</a>
</p>
<p>The <a href="http://www.w3.org">W3C website </a>
contains specifications for web standards and it's
very useful for web designers, developers and software architectures to
navigate this website. For example, you have the CSS 2.1 Specifications
and the XHTML 1.0 Specifications discussing everything from A to Z about
the technology<br>
</p>
<p></p>
</body>
</html>
And here's the result:
As you can see, the CSS code states that every time there's an anchor element with the attribute href, and it has the value http://www.w3.org (the link to the W3C website), it will apply the styles. The syntax is very simple; just use the attribute and the equal sign followed by the string value and you are done. One more thing, you can apply the specific-value attribute selector based on more than one attribute, so you can have something like the following CSS code:
a[href="http://www.w3.org"][target="_blank"]
{
background-color: black;
color: white;
text-decoration: none;
font-size: 1.1em;
font-family: Tahoma;
}
We have added the target attribute's value _blank. You need to add this attribute and its value to the second anchor element in the HTML code, reload the page and you will get the result shown below. Note that the formatting has been applied only to the second anchor element, because it matches the attribute's selector and their values.
