h1 is an html-element that implies some kind of hierarchy. In flash there are no such tags as they only use them for how things look like and not how they are structured.

h1是一个隐含某种层次结构的html元素。在flash中没有这样的标签,因为它们只使用它们来表示事物的样子而不是它们的结构。

You can achieve what you might want to with something similar to the following:

您可以使用类似于以下内容的方式实现您可能想要的目标:

The html:

Headline
Text

The css:

p.headline {font-size: 20pt; font-weight: bold;}
p.text {font-size: 12pt;}

It looks like h1 is not supported by the TextField class. Look in the docs for the htmlText property for a list of supported tags.

看起来TextField类不支持h1。在htmlText属性的文档中查找支持的标记列表。
