HTML <mark> style Attribute

The style attribute on a <mark> tag assigns a unique style to the marked text element. A style contains one or more CSS property/value pairs that define the appearance of the mark element.

Example

  painter.

Using style

The style attribute specifies the style, i.e. look and feel, of the <mark> element.

A style contains any number of CSS property/value pairs, separated by semicolons (;).

The style attribute overrides any other style that was defined in a <style> tag or an external CSS file.

This inline styling affects the current <mark> element only.
