HTML 5 <style> Tag

The HTML <style> tag is used for declaring style sheets within your HTML document.

Each HTML document can contain multiple <style> tags. Each <style> tag must be located between the <head> tags (or a <noscript> element that is a child of a <head> element).

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.

AttributeDescription
mediaSpecifies the device that the styles apply to. Must be a valid media query.

Possible values:

  • all
  • braille
  • print
  • projection
  • screen
  • speech
nonceRepresents a cryptographic nonce ("number used once") which can be used by Content Security Policy to determine whether or not the style specified by an element will be applied to the document. The value is text.
typeSpecifies the style sheet language as a content-type (MIME type).

Global Attributes

The following attributes are standard across all HTML 5 tags (although the tabindex attribute does not apply to dialog elements).

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

For a full list of event handlers, see HTML 5 event handler content attributes.
