CSS Attribute Name in JavaScript

By Xah Lee. Date: . Last updated: .

CSS attribute names are dash separated, example: font-size.

The corresponding property in JavaScript is camelCase: fontSize.

Here's a table of setting styles in CSS and in JavaScript:

CSS Syntax vs JavaScript DOM Syntax
border:solid thin redele.style.border="solid thin red"
font-family:"DejaVu Sans",sans-serifele.style.fontFamily='"DejaVu Sans",sans-serif'
Google Chrome browser console completion
Google Chrome browser console JavaScript keyword completion

A easy way to check style attribute is to use browser's JavaScript console completion feature. Type document.body.style. then press Tab, it'll show a list. [see How to Use Browser Console]
