HTML美化器

HTML 美化器重新缩进标记，使嵌套变得可见：每个子元素进入一个级别，兄弟元素对齐，文档的树结构（在缩小或混乱缩进的 HTML 中不可见）一目了然。标记本身没有改变；仅标签间的空白移动。

每当 HTML 变得扁平化时，您都需要它：生产页面被缩小（查看源代码显示无穷无尽的行），CMS 和电子邮件构建器生成不缩进的汤，复制粘贴的代码片段将其源代码的不一致格式带入您的代码片段中。你看不到的结构就是你无法调试的结构。

粘贴 HTML - 缩小、损坏或仅仅是不一致 - 并使其正确缩进，准备好阅读、编辑或比较。

日常情况：检查生产页面的源代码以查找标签或验证标记（先美化，然后搜索），解开深层嵌套的 div 结构以查找破坏布局的未封闭元素，在提交之前清理模板代码，以及标准化从不同来源组装的片段之间的格式，以便文件不再看起来像赎金注意。

尊重空格的微妙之处：

 和 </code> 内容单独保留（它们的空格是数据），并且内联元素保持合理的间距。相反的操作——去除缩进以进行生产——是 HTML Minifier 的工作；为人类美化，为运输缩小。</p>
