What's the technology behind it?

What's the technology behind websites that fit on desktops, but fits on handheld devices as well, such as Smartphones and tablets? I just got curious about how they do it, so neat!

There are two approaches: responsive or adaptive.

Responsive uses media queries to apply CSS rules based on screen sizes.

Adaptive can be set up using media queries but most of the time they are set up using sophisticated device detection scripts that run on a server.

Here is a great article to help you understand this more.

A well coded website should fit (appear correct) on all current browsers, whether they are riunning on PCs, laptops, tablets or phones. This is because the language/system used does not rely on fixed dimensions but adapts to different browsers etc.
