Using style

#

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

Syntax

#

<th style="CSS-styles">

Values

The style attribute assigns a background to the <th> element.

Clicking the button calls JavaScript which toggles the background and text colors to another value.
