The <big> HTML deprecated element 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.

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.

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

HTML

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

Result

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

CSS

.bigger {
  font-size: larger;
}

HTML

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

Result

This element implements the HTMLElement interface.
