文字/ HTML旁边的内容类型

Question

You probably all know the tag:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

I was wondering what values are there beside text/html for the content attribute?

Answer 1

Common ones include:

• text/xml
• application/json
• image/jpeg

Answer 2

The only content type values you'd want to use for HTML are text/html and application/xhtml+xml for XHTML.

Answer 3

This is the long winded HTML4 way of writing the meta tag. In HTML5 it's much simpler.

New:

<meta charset="UTF-8">

Since you can technically pass just about any form of data to the web browser the

content="text/html

Was meant to tell the browser that is was going to be displaying text/html.

Meta tags are used to describe data about the web page. The data is not displayed, however it can be used for several things. Example supplying and author, giving a description, keywords, and even a document refresh interval.
