Web/HTML/Element/big

ObsoleteThis feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

The obsolete HTML Big Element (<big>) renders the enclosed text at a font size one level larger than the surrounding text (medium becomes large, for example). The size is capped at the browser's maximum permitted font size.

Usage note: As it was purely presentational, this element has been removed in HTML5 and shouldn't be used anymore. Instead web developers should use the CSS font-size property to adjust the font size.

Attributes

This element has no other attributes than the global attributes, common to all elements.

Examples
