jquery - Name of function where png group of icons is used but only one is displayed? -


i'm trying understand problem i'm having slider realized don't know function called can learn more.

the slider has png play, pause , dots in both light , dark (rollover) versions in same image. each displayed on page called for.

i wanted know called can read more , understand how use it.

i think term you're looking "sprites", called "css sprites". idea instead of having multiple small images each thing have larger image icons , change icon using overflow , background-position css properties. improves caching , decreases file requests (which important on limited platforms such mobile or dialup).

here's first google result, , css-tricks reputable: http://css-tricks.com/css-sprites/
