How Do I Style Links Starting With a Specific Prefix Using CSS Attribute Selectors?

How Does It Work?

The a[href^="http:"] selector matches all anchor tags whose href attribute value begins with "http:". This typically includes most external links referencing websites on the internet.

For example, consider the following CSS:

a[href^="http:"] {
   background: url(img/keys.gif) no-repeat right top;
}

This CSS rule will apply a specific background image and position to all links that start with "http:".

Advanced Usage:

You can also use multiple attribute selectors with the same attribute, as shown in the example you provided:

a[href^="http://mysite.com"], a[href^="http://www.mysite.com"] {
   background-image: none; padding-right:0;
}

This rule targets all links starting with "http://mysite.com" or "http://www.mysite.com" and removes their background image and sets their padding to zero. This allows you to customize the appearance of external links within your own website while leaving other external links unaffected.
