Webkit CSS - Selector to Change Color of Highlight

Question

I noticed a cool effect in Chrome at this site, which may or may not be unique to Chrome but possibly for all Webkit browsers.

When the user drags to highlight something, they've changed the default color to pink.

Can you identify the selector?

I would like to see if someone knows of a reference page which describes these kinds of effects.

Answer 1

use

::-moz-selection,
::selection{
    background: #fe57a1;
    color: #fff;
    text-shadow: none;
}
