## What does it do?
* Preserves useful defaults, unlike many CSS resets.
* Normalizes styles for a wide range of elements.
* Corrects bugs and common browser inconsistencies.
* Improves usability with subtle modifications.
* Explains what code does using detailed comments.
## Browser support
* Chrome (last two)
* Edge (last two)
* Firefox (last two)
* Firefox ESR
* Internet Explorer 8+
* iOS Safari (last two)
* Opera (last two)
* Safari 6+
* _[Normalize.css v1 provides legacy browser support](https://github.com/necolas/normalize.css/tree/v1) (IE 6+, Safari 4+), but is no longer actively developed._
## Extended details and known issues
Additional detail and explanation of the esoteric parts of normalize.css.
#### `pre, code, kbd, samp`
The `font-family: monospace, monospace` hack fixes the inheritance and scaling
of font-size for preformatted text. The duplication of `monospace` is
intentional. [Source](https://en.wikipedia.org/wiki/User:Davidgothberg/Test59).
#### `sub, sup`
Normally, using `sub` or `sup` affects the line-box height of text in all
browsers. [Source](https://gist.github.com/413930).
#### `svg:not(:root)`
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](https://lists.w3.org/Archives/Public/public-svg-wg/2008JulSep/0339.html).
#### `select`
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.
#### `[type="checkbox"]`
It is recommended that you do not style checkbox and radio inputs as Firefox's
implementation does not respect box-sizing, padding, or width.
#### `[type="number"]`
Certain font size values applied to number inputs cause the cursor style of the
decrement button to change from `default` to `text`.
#### `[type="search"]`
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).
