HTML标签是构建网页结构的基础，本文详细介绍了常用HTML标签及其功能，包括根元素、头部信息和主体内容的
和、网页标题的
、不同级别的标题标签<h1>到<h6>、段落和换行的<p>和<br>、列表相关的<ul>、<ol>和<li>、链接的<a>、表格构建的<table>、<tr>、<th>和<td>、表单元素<form>、<input>、<textarea>、<select>和<button>，以及多媒体嵌入的<img>、<audio>和<video>。此外，<div>和<span>用于布局和样式化，帮助构建结构清晰的网页。</p><p>HTML常用标签及其功能包括：1. <html>是网页根元素；2. <head>和<body>定义头部信息和主体内容；3. <title>设置网页标题；4. <h1>到<h6>为标题标签；5. <p>和<br>用于段落和换行；6. <ul>、<ol>和<li>用于列表；7. <a>创建链接；8. <table>、<tr>、<th>和<td>构建表格；9. <form>、<input>、<textarea>、<select>和<button>用于表单；10. <img>、<audio>和<video>嵌入多媒体；11. <div>和<span>用于布局和样式化，这些标签帮助构建结构清晰的网页。</p><p><img src="/uploads/20250522/1747886977682ea3815c39f.jpg" alt="html中各种标签的作用 常用html标签功能速查手册"></p><p>在Web开发中，HTML标签是构建网页结构的基础。虽然HTML标签种类繁多，但掌握一些常用标签的功能可以帮助我们更高效地构建和理解网页。今天，我们就来聊聊这些常用的HTML标签及其作用。</p><p>让我们从最基本的标签开始，<code><html></code>标签是网页的根元素，包裹了整个网页内容。紧接着是<code><head></code>和<code><body></code>，分别用于定义网页的头部信息和主体内容。头部通常包含<code><title></code>标签，用于设置网页标题，这个标题会在浏览器的标签页上显示。</p><p>再来说说文本相关的标签。<code><h1></code>到<code><h6></code>是标题标签，用于设置不同级别的标题。<code><p></code>标签用于段落，而<code><br></code>标签用于换行。列表相关的标签有<code><ul></code>（无序列表）和<code><ol></code>（有序列表），以及<code><li></code>（列表项）。链接的创建离不开<code><a></code>标签，它的<code>href</code>属性指定链接的目标地址。</p><p>表格的构建需要用到<code><table></code>标签，<code><tr></code>定义表格行，<code><th></code>定义表格头部单元格，<code><td></code>定义表格数据单元格。表单的创建则依赖<code><form></code>标签，常见的表单元素有<code><input></code>（输入框）、<code><textarea></code>（多行文本输入框）、<code><select></code>（下拉列表）和<code><button></code>（按钮）。</p><p>多媒体内容的展示也离不开特定的标签。<code><img></code>标签用于插入图片，<code>src</code>属性指定图片的URL。<code><audio></code>和<code><video></code>标签分别用于嵌入音频和视频内容。</p><p>最后，<code><div></code>和<code><span></code>是两个非常灵活的标签。<code><div></code>通常用于布局，创建块级元素，而<code><span></code>用于内联元素，通常用于文本的样式化。</p><p>通过这些标签，我们可以构建出结构清晰、功能丰富的网页。以下是一些常用标签的示例代码：</p><pre><!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>My Web Page</title>
</head>
<body>
<h1>Welcome to My Web Page</h1>
<p>This is a paragraph of text.</p>
<br>
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
<a href="https://www.example.com">Visit Example.com</a>
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
</tr>
<tr>
<td>Row 1, Cell 1</td>
<td>Row 1, Cell 2</td>
</tr>
</table>
<form>
<input type="text" name="username" placeholder="Username">
<textarea name="comment" placeholder="Comment"></textarea>
<select name="option">
<option value="option1">Option 1</option>
<option value="option2">Option 2</option>
</select>
<button type="submit">Submit</button>
</form>
<img src="image.jpg" alt="An image">
<audio controls>
<source src="audio.mp3" type="audio/mpeg">
</audio>
<video controls>
<source src="video.mp4" type="video/mp4">
</video>
<div style="background-color: lightgray;">
This is a div element.
</div>
<span style="color: red;">This is a span element.</span>
</body>
</html></pre><p>在使用这些标签时，需要注意一些常见的误区和最佳实践。例如，<code><div></code>和<code><span></code>虽然灵活，但过度使用会导致网页结构混乱，影响SEO和可访问性。表单的<code><input></code>标签需要指定<code>type</code>属性，以确保用户体验和数据验证的准确性。<code><img></code>标签的<code>alt</code>属性是必不可少的，它在图片无法加载时提供替代文本，提升网页的可访问性。</p><p>总之，HTML标签是网页构建的基石，理解和正确使用这些标签可以帮助我们创建出结构清晰、功能丰富的网页。希望这篇文章能为你提供一个快速参考，助你在Web开发的道路上更进一步。</p><p>本篇关于《HTML标签大全：常用标签速查手册》的介绍就到此结束啦，但是学无止境，想要了解学习更多关于文章的相关知识，请关注golang学习网公众号！</p>
