# normalize.css v3
|
||
|
||
Normalize.css is a customisable CSS file that makes browsers render all
|
||
elements more consistently and in line with modern standards.
|
||
|
||
The project relies on researching the differences between default browser
|
||
styles in order to precisely target only the styles that need or benefit from
|
||
normalizing.
|
||
|
||
[View the test file](http://necolas.github.io/normalize.css/latest/test.html)
|
||
|
||
## Install
|
||
|
||
* [npm](http://npmjs.org/): `npm install --save normalize.css`
|
||
* [cdnjs](https://cdnjs.com/libraries/normalize)
|
||
* [Download](http://necolas.github.io/normalize.css/latest/normalize.css).
|
||
|
||
No other styles should come before Normalize.css.
|
||
|
||
It is recommended that you include the `normalize.css` file as untouched
|
||
library code.
|
||
|
||
## 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 improvements.
|
||
* Explains what code does using detailed comments.
|
||
|
||
## Browser support
|
||
|
||
* Chrome (latest)
|
||
* Edge (latest)
|
||
* Firefox (latest)

|
||
|
||
[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
|
||
|
||
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](http://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](http://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. [SVG

|
||
|
||
#### `input[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).
|
||
|
||
#### `legend`
|
||
|
||
Adding `border: 0` corrects an IE 8–11 bug where `color` (yes, `color`) is not
|
||
inherited by `legend`.
