Legibility
==========

A WebExtension that enables you to add custom CSS styles to websites. Unlike a
global user stylesheet, this extension loads a separate stylesheet for each
site, giving you control over the appearance of any site. For example, sites
with poorly legible typography can be easily corrected for better a reading
experience.


## Usage
Let’s say we want to modify the font of an article on `www.example.com`. Add an
`www.example.com.css` file in the extension’s `css/` directory:

``` css
/* legibility/css/www.example.com.css */
article {
	font: 18px/1.7em Georgia !important;
}
```

Upon reloading the page, the custom stylesheet should now be applied.

Stylesheets must use a filename matching the website’s domain (including
subdomains), and terminated by a `.css` extension.


### Domain wildcards
Styles can be applied to multiple domains or subdomains using domain-level
wildcards. For the host `www.example.com`, the following CSS files will apply:

* `%.css`: Applies styles to all hosts
* `%.com.css`: Applies styles to all `.com` domains
* `%.example.com.css`: Applies styles to all subdomains under `example.com`
* `www.example.com.css`: Applies styles to the `www.example.com` host


## Install
This extension should be installed unpacked to allow you to freely add and
modify stylesheets in the `css/` directory.
