# Highlight
Use this extension to render highlighted text with `<mark>`. You can use only default `<mark>` HTML tag, which has a yellow background color by default, or apply different colors.

Type `==two equal signs==` and it will magically transform to <mark>highlighted</mark> text while you type.
