Could some one please explain the difference between a div class and div id, in simple english. Thanks =)
In simplest terms, a class can be used on more than one element. An id is limited to one element on a page.
id can be used to reference calls in javascripts and DOM so an id must be declared once only. it's like a name of particular person in a class room wherein you can call him/her by name to refer to him/her specifically. whereas a class refers to a more generic usage. its like using the term "aspirin" without specifically naming a specific brand. it can be used multiple times anywhere on the page.
Vagrant's link explains best, so instead, for your entertainment, I'll tell you something entirely off-topic until the thread dies (this forum seriously needs some stickies). The drug known in North America as "Tylenol" actually has two valid, legal names, one for North America (acetaminophen) and another the rest of the world uses (paracetamol). It's pretty unusual for one drug to have two valid names like this.
