To link CSS files to HTML documents, you need to use the <link> tag in the
of HTML. 1. Use <link rel="stylesheet" href="styles.css"> to introduce external CSS files, make sure that the rel attribute is "stylesheet" and that href points to the correct CSS file path; 2. Place the tag in , as shown in the example: add <link> tags after
and
to correctly load the style; 3. Ensure that the file path is accurate, use href="styles.css" for the same directory, use href="css/styles.css" for the subdirectory, and use href="../styles.css" for the upper directory; 4. Follow best practices: always put <link> in , prioritize external CSS to improve maintenance and caching effects, and link multiple CSS files such as reset.css and theme.css. Pay attention to the order to determine the override relationship of the style. As long as the path and syntax are correct, the browser can successfully apply the style. <p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175373114332707.jpeg" class="lazy" alt="How to link a CSS file to an HTML document?"></p>
