HTML代码大全(很全的)
HTML（HyperText Markup Language，超文本标记语言）是构建网页的基础。对于任何想要创建和设计网页的人来说，掌握HTML代码是至关重要的。下面，我们将对一些常用的HTML标签及其用法进行全面、详细的介绍，为您打造一份“很全的”HTML代码大全。

class="language-html"><h1>这是一级标题</h1> <h2>这是二级标题</h2> <p>这是一个段落。</p> <strong>这是加粗文本</strong> <em>这是斜体文本</em></code></pre> <ul> <li><code><h1></code>到<code><h6></code>：定义标题，<code><h1></code>是最大的标题。</li> <li><code><p></code>：定义段落。</li> <li><code><strong></code>：加粗文本，表示重要性。</li> <li><code><em></code>：斜体文本，表示强调。</li> </ul> <h2>列表</h2> <h3>无序列表</h3> <pre><code class="language-html"><ul> <li>项目1</li> <li>项目2</li> <li>项目3</li> </ul></code></pre> <ul> <li><code><ul></code>：定义无序列表。</li> <li><code><li></code>：定义列表项。</li>

class="language-html"><a href="https://www.example.com">访问示例网站</a></code></pre> <ul> <li><code><a></code>：定义超链接，<code>href</code>属性指定链接的目标地址。</li> </ul> <h3>图像</h3> <pre><code class="language-html"><img src="image.jpg" alt="图像描述"></code></pre> <ul> <li><code><img></code>：嵌入图像，<code>src</code>属性指定图像的URL，<code>alt</code>属性提供图像的替代文本。</li> </ul> <h2>表格</h2> <pre><code class="language-html"><table> <tr> <th>表头1</th> <th>表头2</th> </tr> <tr> <td>数据1</td> <td>数据2</td> </tr> </table></code></pre> <ul> <li><code><table></code>：定义表格。</li> <li><code><tr></code>：定义表格行。</li> <li><code><th></code>：定义表头单元格。</li> <li><code><td></code>：定义标准单元格。</li> </ul> <h2>表单</h2> <pre><code class="language-html"><form action="/submit" method="post"> <label for="name">姓名:</label> <input type="text" id="name" name="name"> <input type="submit" value="提交"> </form></code></pre> <ul> <li><code><form></code>：定义表单，<code>action</code>属性指定表单提交的URL，<code>method</code>属性指定HTTP方法（如<code>get</code>或<code>post</code>）。</li> <li><code><label></code>：定义表单元素的标签。</li> <li><code><input></code>：定义输入字段，<code>type</code>属性指定输入类型（如<code>text</code>、<code>submit</code>等）。</li> </ul> <h2>语义化标签</h2> <p>HTML5引入了许多语义化标签，提高了代码可读性和SEO： </p><img
