This implementation is from
https://cloudfour.com/thinks/see-no-evil-hidden-content-and-accessibility/#showing-additional-content-for-screen-readers
which is a slight tweak from https://accessibility.18f.gov/hidden-content/ .
https://webaim.org/techniques/css/invisiblecontent/#techniques
has slightly different CSS clip, rect (1px) for all dimensions.

WARNING:

Template:Fraction and friends use this styles.css page and class directly rather
than going through the template.
