Q: 哪一种状况下应该使用small
标签?当你想在h1
标题后建立副标题?仍是当在footer
里面增长版权信息?

The HTML Small Element (
<small>
) makes the text font size one size smaller (for example, from large to medium, or from small to x-small) down to the browser's minimum font size. In HTML5, this element is repurposed to represent side-comments and small print, including copyright and legal text, independent of its styled presentation.
Q: 在一个结构良好的web网页里,多个h1
标签会不利于SEO吗?
A: 不影响。
According to Matt Cutts (lead of Google's webspam team and the de facto expert on these things), using multiple
<h1>
tags is fine, as long as you're not abusing it (like sticking your whole page in an<h1>
and using CSS to style it back to normal size). That would likely have no effect, and might trigger a penalty, as it looks spammy.
If you have multiple headings and it would be natural to use multiple
<h1>
's, then go for it.
