❮ Previous Complete CSS Reference Next ❯

Example

Set the width of the tab character to 16 spaces:

pre {-moz-tab-size: 16;} /* Firefox */
pre {tab-size: 16;}

Definition and Usage

The tab-size property specifies the width of a tab character.

In HTML, the tab character is usually displayed as a single space-character, except for some elements, like <textarea> and <pre>, and the result of the tab-size property will only be visible for those elements.
