Via Think Vitamin I find a cool way to highlight the current element. Lots of people do this by calling some kind of javascript library, it’s so common it’s been dubbed the yellow fade technique. But javascript isn’t really needed, you just need CSS and an image.

First: you can jump to any id on the current page by appending #some-id-here to the url. This includes all the “semantic” ids you’ve added to the page such as #content, #sidebar, and so on. Very useful if you want to point out a certain section of a page to a friend, just look at the source, try to find an id nearby, and add it to the url.

If you want to make things even easier on your own site, you can visually highlight things that get referenced via the above method. That’s where the :target psuedo selector jumps in to save your day. Please note that :target is CSS3, and only currently works in non-crap browsers. But perhaps this effect is something not all users really need?

a:target {
   background: #234af5;
}

This highlights all links that get referenced via the URL with a nice blue color. So they need an id added. Makes perfect sense for all kinds of documentation where you want to refer someone to a certain method or even sentence.

But it gets better:

:target {
   background: url(a href="http://friendlybit.com/images/yellow-fade.gif">yellow-fade.gif</a>);
}

We’ve removed the limit of only targeting links with by using :target straight off. So all targeted elements will get affected by this rule. What next? Well, we use a small animated image to fade from one color to the next. It’s a really easy way to add dynamics to a page.

Try the effect by jumping to the code example above.

I really think this makes internal links a whole lot more useful, especially for jumping to the bottom of the page, where it’s not possible for the browser to scroll down enough to get the targeted element to the top. Needless to say, I’ve added this effect to this site too. Hope you can find something to use it for too.
