You may encounter <big> while maintaining an older website. It is a legacy HTML element, so the goal is to recognize it and replace it—not to start using it in new pages.
What the old element was for
Text that looks larger. In older markup, developers sometimes mixed page appearance, browser plug-in behavior, and document structure in the same HTML file.
big controlled visual size rather than meaning.
Use this modern alternative
A better modern choice is span with CSS. This example focuses on the meaning of the replacement:
<section>
<span class="larger-text">A featured note</span>
</section>
Why the replacement is better
Modern HTML makes the content easier to maintain, style, and understand across browsers.
With modern markup, HTML describes the content, CSS controls presentation, and JavaScript is added only if the feature needs changing behavior.
Updating an older page
Find one use of <big> in the old source. Work out the meaning the author intended, replace it with the supported structure, and compare the result in your browser. Do not remove meaningful content while updating the markup.
Common Beginner Mistakes
- Copying
<big>from an old tutorial into a new website. - Assuming a browser displaying obsolete markup means the markup is recommended.
- Replacing an old tag with something that changes its meaning rather than its appearance.
Key Takeaways
<big>is legacy markup, not a recommended new HTML feature.- Prefer span with CSS.
- big controlled visual size rather than meaning.
