JigSass Generic Normalize

Modular, configurable, opt-in browser normalization

JigSass Normalize is a modularized and configurable version of Nicolas Gallagher and Jonathan Neal's normalize.css at version 4.0.0.

Normalize.css is a modern alternative to css resets, which preserves useful defaults and corrects bugs and common browser inconsistencies.

Installation

Using npm:

npm i -S jigsass-generic-normalize

Usage

  @import 'path/to/jigsass-generic-normalize'/scss/index;

Jigsass Normalize will not output any CSS, unless explicitly included using one of the mixins.

Jigsass Normalize's configuration variables allow overriding the very few default opinionated choices made by normalize.css.

To include all or parts of JigSass Normalize's submodules, use the jigsass-normalize mixin.

JigSass Normalize offers mixins for including each of the submodules, and a shortcut mixin, jigsass-normalize, to include all parts at once.

The styles of each JigSass Normalize submodule will only be included a single time, where they were imported.

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.

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).

Development

It is a best practice for JigSass modules to not automatically generate css on @import, but rather have to user explicitly enable the generation of specific styles from the module.

Contributions in the form of pull-requests, issues, bug reports, etc. are welcome. Please feel free to fork, hack or modify JigSass Generic Normalize in any way you see fit.

Writing documentation

Good documentation is crucial for scalability and maintainability. When contributing, please do make sure that all Sass functionality (functions, mixins, variables and placeholder selectors) is well documented.

Documentation is auto-generated using SassDoc

Running tests

gulp lint will, well, lint the contents scss files in the scss directory.

gulp test with run module's test using Mocha and Sassaby.

gulp tdd will watch both the Sass files and the test specs for changes, and will run tests automatically upon them.

Writing tests

JigSass Generic Normalize tests are written using Sassaby and Mocha. Spec files are located in the test directory.

Mocha allows us to place a call to before() in the root of any test file and it will be run once, before all the other tests in every test_*.js file. We can also require() files and assign them to the global object to make them available to all test_*.js files.

jigsass-generic-normalize uses a file called helper.js can be used to set up mocha globals requires and before().

In addition to Sassaby's testing functions, jigsass-generic-normalize makes a few Sass functions available to the test suite, for use inside Sassaby tests:
