Wow, im starting to get active on devbest :3, well if you saw my last thread im trying to learn how to code, and now im trying to learn the difference between ID's and classes.. It seems to be the same thing, and when should i use what? Thanks

When it comes to web design there are two main style sheet selectors

ID's and Classes

What i have learned is that IDS ( # ) are used one in every tag, but classes ( . ) can be used many times in one tag... example?

<div id="container" class="Friday Sunshine Green">

ID is unique. Classes are shared.

ID is unique. Classes are shared.

Remember though The "#" Selector is used for ID's and ' . ' are used for classes! ;3 .. That was way simpler lolz

Classes are more unique and use.
So what Garett said.
