Question

What are the properties supporting CSS styles for a document element?

(a) style and font

(b) style and className

(c) size and style

(d) className and font

I have been asked this question in an international level competition.

This key question is from JavaScript in Web Browsers topic in chapter Server-Side and Client-Side Scripting of JavaScript

Answer 1

Correct option is (b) style and className

To explain I would say: Each Element object has style and className properties that allow scripts to specify CSS styles for a document element or to alter the CSS class names that apply to the element. firstChild returns the first child node as an element node, a text node or a comment node (depending on which one’s first).
