Subject: Docs: rename "Screen readers" helper page to "Visually hidden"
X-Git-Tag: v5.0.0-alpha2~195
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3a79335a0b21cc5bbd3f133e63aec6052694fc20;p=thirdparty%2Fbootstrap.git

Docs: rename "Screen readers" helper page to "Visually hidden"

"screen readers" is quite reductive, as there are other assistive technologies. content hidden this way is even announced by things like Alexa/Siri etc, so it's not so much just "screen readers".
in the long run, we may even consider changing the actual classnames (maybe `.visually-hidden` / `.visually-hidden-focusable`, though admittedly that's a bit verbose).

also includes a tiny tweak to layout.md to generalise the note about using `.sr-only`

 Use the `.col-auto` class to create horizontal layouts. By adding [gutter modifier classes]({{< docsref "/layout/gutters" >}}), we'll have gutters in horizontal and vertical directions. The `.align-items-center` aligns the form elements to the middle, making the `.form-checkbox` align properly.
