This feature is obsolete.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 HTML Big Element (<big>) makes the text font size one size bigger (for example, from small to medium, or from large to x-large) up to the browser's maximum 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 CSS properties.


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

Example 1

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

Example 2 (CSS alternative)

  This is the first sentence. <span style="font-size:1.2em">This whole 
  sentence is in bigger letters.</span>


This is the first sentence. This whole sentence is in bigger letters.

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.
