Learn CSS, Selectors, part 2 - The Specific-Values Attribute Selector (Page 4 of 7 )
The specific-values attribute selector is very similar to the specific-value attribute selector. Instead of matching only one value for the element's attribute, this selector matches one of the multiple space separated values like the following:
Note the use of the tilde symbol with the equal sign, and the space between the two string values. This selector states that any anchor element that has the href attribute value set to http://www.w3.org or http://www.w3.org/TR/CSS21 will have the above styling rule. Unfortunately, there is no browser support for this selector yet.
The lang value Attribute Selector
Actually, this attribute has been defined for certain behavior. The selector applies the rule if the value of the attribute matches the specified value, or the specified value with added "-". Let's look at an example. Modify the CSS file to look like this:
Now modify the first <p> element in the HTML to look like this (just add the lang attribute and set the value to "en-us"):
<p lang="en-us">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>
The selector states that any <p> element that has the attribute lang, that has the value that begins with "en" or "en-" will have blue text. This selector applies the formatting rule if a match of the specified value has been found, or a match of the value plus the "-" symbol like "en" or "en-" has been found.
