5 | # Font Feature Fibbing
6 |
7 | Hey, do you support the `font-feature-settings` CSS property? Safari, look—I know you’re lying!
8 |
9 | This module is (somewhat intentionally) simple—you will find out whether or not `font-feature-settings` is supported, but not _what_ `font-feature-settings` specifically. Its primary target is Safari v9.2 and lower, which misrepresented whether or not it actually exposed `font-feature-settings` to front-end designers and developers.
10 |
11 | ## Getting started
12 |
13 | If you’re using [Browserify](http://browserify.org), first install the project:
14 |
15 | ```sh
16 | npm install --save font-feature-fibbing
17 | ```
18 |
19 | Then, `require` it and do something based on the result.
20 |
21 | ```js
22 | var supportsFontFeatureSettings = require('font-feature-fibbing');
23 |
24 | if (!supportsFontFeatureSettings()) {
25 | // Add a class to ``
26 | document.documentElement.className += ' is-withoutFontFeatureSettings';
27 | }
28 | ```
29 |
30 | If you’re not using a module system, you can also dropin the [font-feature-fibbing.js](dist/font-feature-fibbing.js) file with a similar result:
31 |
32 | ```html
33 |
34 |
40 | ```
41 |
42 | In this case you’ll almost definitely want to include it with whatever other build process you’re using to include `font-feature-fibbing.js` in your main JavaScript file.
