The Sass port of normalize.css

This project is the Sass version of Normalize.css, a collection of HTML element and attribute rulesets to normalize styles across all browsers. This port aims to use a light dusting of Sass to make Normalize even easier to integrate with your website. To learn about why Normalize.css is so amazing, skip to the "normalize.css" section below.

This Sass port currently utilizes:

  • Browser support variables: Allowing you to easily add/drop support for any browser by modifying a single Sass variable.
  • Vertical rhythm mixins: Allowing you to alter the font-size, line-height and margins in Normalize’s output without hacking the library.

In addition, Normalize.css has 2 major versions: version 4 (without “legacy browser” support) and version 1 (with support for IE 6/7, etc.) This Sass port combines the two versions into one file so that you can easily toggle between the two versions using its browser support variables.

Did a client wait until the last minute to mention their CEO uses IE 6? Simply update your $support-for variable and recompile your Sass files. Details can be found at

normalize.css v4

A modern alternative to CSS resets

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.

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.


Install using one of the following methods:

  • Download directly from the project page.
  • Install with npm: npm install --save normalize-scss
  • Install with Bower: bower install --save normalize.scss
  • Install with Ruby Gem: gem install normalize-scss
    and, if using Compass, add require "normalize-scss" to your config.rb file. Note: if you want to alter the _normalize.scss file after installation (see "how to use it" below), you can use the gem list --details normalize-scss command to show you where the normalize-scss files were installed.

How to use it

There is a fantastic introduction to the project and brief instructions how to use it in the About normalize.css article.

You can use the Sass port of Normalize in one of several methods, following the "About normalize.css" article's suggestions:

Approach 1: Download and use normalize-scss as a starting point for your own project's base Sass, customising the values to match the design's requirements. (The best approach, IMO.)

  1. Copy the normalize-scss files to your sass directory so that you can alter it as you include it in your project. To aid with this method, normalize-scss includes several ready-made "fork" versions:
  2. The normalize-scss code uses the support-for module, so add it

Approach 2: Install and include normalize-scss untouched and then build upon it, overriding the defaults later in your Sass when necessary. Just import normalize-scss like any normal Sass module by:

  1. Set variables to override the default normalize-scss variables.
  2. Import with @import "normalize";
  3. Output the CSS rules with @include normalize();

Alternatively, you can import normalize-scss immediately into your main Sass file without needing to use the normalize() mixin by:

  1. (Optionally) set variables to override the default normalize-scss variables.
  2. Import with @import "normalize/import-now";

Note: if you use wiredep, normalize-scss's bower.json points at the normalize/import-now Sass partial. If you don't wish to immediately output the CSS, you will need to override the Sass partial that wiredep grabs from normalize-scss.

Browser support

The exact browsers supported in your project is controlled by the browser support variables. See

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.

sub, sup

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).

Updates to most CSS rules should be reported to the upstream Normalize.css project. Updates to the Sass should be reported in the Normalize-scss project.
