如何防止< H1>占用比他们需要更多的宽度
如果我制作< h1> 标题，默认情况下，其宽度设置为100％。有没有办法确保将其宽度设置为尽可能最小的值？我需要这个来做特殊的CSS边框。
If I make an <h1> title, its width is set to 100% by default. Is there a way to make sure its width is set to the smallest value possible? I need this to do special CSS stuff with borders.
你可以给它 display：inline ，这会使它表现得像任何文本元素一样（ h1 的缺省值是 display：block >）。还有其他一些方法 - 例如 float：left - ，但我觉得这是最简单的方法，也是副作用最少的方法。
You can give it display: inline, this will make it behave like any text element (The default for h1 is display: block). There are other ways - float: left for example - , but I find this the simplest and the one with the fewest side effects.
请注意，您可能需要添加< br> 以确保在h1之后换行。
Note that you will then probably have to add a <br> to ensure a line break after the h1.
