Using style

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