Answer
Inline, internal, and external CSS differ by their location and reuse. β’ Inline declarations are written in an elementβs style attribute. β’ Internal rules are written in a style element in the document. β’ External rules are loaded from a separate style sheet with a link element.
💡 Simple Example
<link rel="stylesheet" href="site.css">
<style>.card { padding: 1rem; }</style>
<div style="color: navy">Card</div>
⚡ Quick Revision
Inline targets one element, internal stays in one document, and external CSS is reusable.
