The HTML content attribute

Attribute All modern browsers Updated
Quick answer

The HTML content attribute provides the value for a meta tag's name or http-equiv declaration. It is used on the <meta> element.

Overview

The content attribute holds the value of a meta declaration. It is used on document head elements like <meta>, <link> and <script>.

It belongs to the document head — metadata, stylesheet and script loading, encoding and resource hints. These attributes shape how the page is interpreted and how efficiently its resources load.

Syntax

<meta name="description" content="A short page summary for search engines.">

Values

Value
A string whose meaning depends on the accompanying name/http-equiv.

Best practices

  • Declare the character encoding with <meta charset="utf-8"> first in the <head>.
  • Load scripts with defer (or as modules) so they do not block parsing.
  • Protect third-party resources with integrity and crossorigin (Subresource Integrity).
  • Use resource hints like preload deliberately, paired with the right as value.
