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.
Install
- npm:
npm install --save normalize.css - Component(1):
component install necolas/normalize.css - Bower:
bower install --save normalize.css - cdnjs
- Download.
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.

Normalize.css v1 provides legacy browser support (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 preformated text. The duplication of monospace is
intentional. Source.
sub, sup
Normally, using sub or sup affects the line-box height of text in all
browsers. Source.
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.
