PAGE: invert colors
command
/invc
description
Invert colors on the page.

Useful for viewing white pages in "night mode" or vice versa.

Some people find that dark pages cause less eyestrain, particularly at night time.

Other people dislike dark pages, because eyes that have adjusted to them may be temporarily strained by viewing brighter pages soon after.

Only changes HTML, not pictures.
