There are two ways to introduce CSS files: </p><p><strong>1. Use the <code><link></code> tag</strong></p><p><code><link>## The # tag is used to link external style sheet files to HTML documents. The syntax is as follows: </code></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre><code class="html"><link rel="stylesheet" href="style.css"></code></pre><div class="contentsignin">Copy after login</div></div> Among them: <p></p><ul><li>rel<code> attribute specifies the relationship between the linked file and the current document, </code>stylesheet<code> indicates that this is a Style sheet file. The </code></li><li>href<code> attribute contains the path to the stylesheet file to be associated. </code></li></ul><p>2. Use the <strong><style><code> tag </code></strong></p><p><style><code> tag is used in HTML CSS styles are defined inside the document. The syntax is as follows: </code></p><div class="code" style="position:relative; padding:0px; margin:0px;"><pre><code class="html"><style> body { background-color: #f0f0f0; font-family: Arial, sans-serif; } Copy after loginWhere: <code> tag contains the CSS rules to be defined. </code></li>CSS rules use standard CSS syntax, including selectors (<li>body<code>) and style declarations (</code>background-color<code>, </code>font-family<code>) . </code></li></ul><p>Note: <strong></strong></p><ul>No matter which method is used, the CSS file or <li><style><code> tag should be placed Within the </code><head><code> section of the HTML document. </code></li>If you have multiple CSS files to include, you can use multiple <li><link><code> tags or </code><style><code> tags. </code></li>The external style sheet file can be located in the same or a different location as the HTML document, but the correct path must be provided. <li></ul></body></html>
