This feature is obsolete.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.


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


Here we see examples showing the use of <big> followed by an example showing how to accomplish the same results using modern CSS syntax instead.

Using <big>

This example uses the obsolete <big> element to increase the size of some text.


  This is the first sentence. <big>This whole 
  sentence is in bigger letters.</big>


Using CSS font-size

This example uses the CSS font-size property to increase the font size by one level.


.bigger {
  font-size: larger;


  This is the first sentence. <span class="bigger">This whole 
  sentence is in bigger letters.</span>


DOM interface

This element implements the HTMLElement interface.

Implementation note: Up to Gecko 1.9.2 inclusive, Firefox implements the HTMLSpanElement interface for this element.
