Additional detail and explanation of the esoteric parts of normalize.
The font-family: monospace, monospace
hack fixes the inheritance and scaling
of font-size for preformatted text. The duplication of monospace
is
intentional. Source.
Normally, using sub
or sup
affects the line-box height of text in all
browsers. Source.
Adding overflow: hidden
fixes IE9's SVG rendering. Earlier versions of IE
don't support SVG, so we can safely use the :not()
and :root
selectors that
modern browsers use in the default UA stylesheets to apply this style.
Source.
By default, Chrome on OS X and Safari on OS X allow very limited styling of
select
, unless a border property is set. The default font weight on optgroup
elements cannot safely be changed in Chrome on OSX and Safari on OS X.
It is recommended that you do not style checkbox and radio inputs as Firefox's implementation does not respect box-sizing, padding, or width.
Certain font size values applied to number inputs cause the cursor style of the
decrement button to change from default
to text
.
The search input is not fully stylable by default. In Chrome and Safari on
OSX/iOS you can't control font
, padding
, border
, or background
. In
Chrome and Safari on Windows you can't control border
properly. It will apply
border-width
but will only show a border color (which cannot be controlled)
for the outer 1px of that border. Applying -webkit-appearance: textfield
addresses these issues without removing the benefits of search inputs (e.g.
showing past searches). Safari (but not Chrome) will clip the cancel button on
when it has padding (and textfield
appearance).
In Edge, placeholders will disappear on relative
or absolute
positioned
<input>
elements if you use opacity
less than 1
due to a bug.
