隐式标签名

隐式标签名

Even with such a powerful abbreviation engine, which can expand large HTML structures from short abbreviation, writing tag names may be very tedious.

尽管可以利用强大的缩写引擎从简短的缩写展开大段的 HTML，但是书写标签仍然可能让人烦。

In many cases you can skip typing tag names and Emmet will substitute it for you. For example, instead of div.content you can simply write .content and expand it into <div class="content"></div>.

在许多情况下可以省略标签名，Emmet 会妥善处理。比如不写 div.content 而写 .content，可以展开为 <div class="content"></div>。

How it works 工作原理

When you expand abbreviation, Emmet tries to grab parent context, e.g. the HTML element, inside which you’re expanding the abbreviation. If the context was grabbed successfully, Emmet uses its name to resolve implicit names:

当展开缩写时，Emmet 尝试获取缩写所处位置的父元素上下文，比如 HTML 元素。如果获取成功，Emmet 使用它的名字来解析隐式标签名：

As you can see from the example above, Emmet looks at the parent tag name every time you’re expanding the abbreviation with an implicit name. Here’s how it resolves the names for some parent elements:

如你所见，当展开隐式标签名时 Emmet 查找父元素标签名。下面是 Emmet 解析机制：

• li for ul and ol
• tr for table, tbody, thead and tfoot
• td for tr
• option for select and optgroup
