Customizing CSS Tabs

Setting the width for CSS tabs

By using the CSS tab-size property, you can define a custom size for the tab character:

pre {
    tab-size: 24;
}

Note: due to the whitespace collapse principle, CSS tabs or multiple spaces can only be displayed in preformatted text.

Theory is great, but we recommend digging deeper!

Syntax for customizing CSS tabs

The CSS tab-size property only takes one value that define the width of the tab character:

tab-size: width;

You can specify it in two ways:

• Length units can be used to define exact width
• A unitless number defines how many spaces the tab will be equal to in width
