<big>
The <big> element was used to render text in a larger font size than the surrounding text. It was a purely presentational element with no semantic meaning, making text one size larger in the browser's font size scale.

Deprecation Warning
This element is obsolete and should not be used. The <big> element is not supported in HTML5. Unlike <small>, which was redefined with semantic meaning, <big> was completely removed from the specification.
The <big> element had no semantic value—it was purely presentational. Since text size is a presentational concern, it should be handled by CSS rather than HTML markup.
Syntax
<big>larger text</big>
The element could be nested to increase size further:
<big><big>even larger text</big></big>
Modern Alternatives
Use CSS properties instead of the <big> element:
Old HTML (Obsolete)
<p>This is <big>larger text</big> in a paragraph.</p>
Modern CSS Equivalent
<p>This is <span style="font-size: larger;">larger text</span> in a paragraph.</p>
Using Relative Units
<p>This is <span style="font-size: 1.2em;">larger text</span> in a paragraph.</p>
Better: CSS Classes
<!-- HTML -->
<p>This is <span class="larger">larger text</span> in a paragraph.</p>
<!-- CSS -->
.larger {
font-size: 1.2em;
}
For Emphasis (Consider Semantics)
<!-- If the larger text conveys importance -->
<p>This is <strong class="emphasis">important text</strong> in a paragraph.</p>
<!-- CSS -->
.emphasis {
font-size: 1.2em;
}
When to Avoid
Always avoid using <big>. There is no valid use case for this element:
- It is obsolete in HTML5 and not supported
- It has no semantic meaning
- It fails validation for HTML5 documents
- CSS provides precise control over font sizing
- Consider whether larger text conveys meaning (use <strong> or <em>) or is purely decorative (use CSS)
