Compatibility of CSS, HTML and JavaScript features (compat-api)

compat api contains hints to check if your CSS, HTML, and JavaScript
have deprecated or not broadly supported features.

Why is this important?

You need to know if all the properties that you are using in your files
are compatible with the target browsers that you want to support.

Hints

* [compat-api/css][compat-api-css]
* [compat-api/html][compat-api-html]

How to use these hints?

This package is installed automatically by webhint:

``bash
npm install hint --save-dev
`

To use it, activate it via the [.hintrc][hintrc] configuration file:

`json
{
"connector": {...},
"formatters": [...],
"hints": {
"compat-api/css": "error",
"compat-api/html": "error",
...
},
"parsers": [...],
...
}
`

Note: The recommended way of running webhint is as a devDependency` of
your project.
