HTML tags that aren't allowed in AMP

You're free to use most HTML elements in your AMP pages. Some are restricted however. Generally, elements that have a performance impact, for example, elements that involve external HTTP requests, are forbidden. For some of these, replacement AMP tags provide similar functionality but in a performance-optimized way.

In general, you can use any HTML tag as usual if it is not listed in the following sections in the forbidden or has-an-AMP-alternative tag lists.
