The <style> HTML element contains style information for a document, or part of a document. It contains CSS, which is applied to the contents of the document containing the <style> element.

#Attributes

• blocking: This attribute explicitly indicates that certain operations should be blocked on the fetching of critical subresources. @import-ed stylesheets are generally considered as critical subresources, whereas background-image and fonts are not. The operations that are to be blocked must be a space-separated list of blocking tokens listed below.

  • render: The rendering of content on the screen is blocked.

• media: This attribute defines which media the style should be applied to. Its value is a media query, which defaults to all if the attribute is missing.

• nonce: A cryptographic nonce (number used once) used to allow inline styles in a style-src Content-Security-Policy. The server must generate a unique nonce value each time it transmits a policy. It is critical to provide a nonce that cannot be guessed as bypassing a resource's policy is otherwise trivial.

• title: This attribute specifies alternative style sheet sets.
