7th ques: Why & When we use id & class?

Filed under: --- Level: 2, ♥ List of CSS Questions — cssquestions @ 3:49 am

id & class is the heart of CSS. Do you know why we need to use id & class. And when we use “id”, when we use “class”?

 This is an VERY, VERY, VERY important question.

And one more extra question: do you know what does “div” mean? what “div” is stand for?

  1. As some examples on web I’ve seen, “class” is used to group elements and id to to identify one unique element.
    Classes are used to style just a few of tags in a way. “Ids” work exactly like “classes” except for one thing; you can only have one “id” with a certain name in each of your HTML documents.

    Div is short for “division”. I’m very confused about div. Can u explain more?

  2. Google: CSS box model

    http://www.google.com.vn/search?hl=vi&q=CSS+box+model&meta=

    And read some about “box model” in CSS box, or view it on CSS training Video.

    Anh then, if you still don’t understand, i’ll explain it :D

    Every tag (h1, p, a, etc.) creates a box, and div-tag, of course, create a box.

    id & class is the way we use to name the tag(s).
