rework-inherit

Inherit 

Inherit mixin for rework.
Allows you to inherit __all__ the rules associated with a given selector.

$3

``js
var inherit = require('rework-inherit')

var css = rework(inputCSS)
.use(inherit())
.toString()
`

#### Inherit(options{})

Option parameters:

* propertyRegExp - Regular expression to match the "inherit" property.
By default, it is /^(inherit|extend)s?$/i, so it matches "inherit", "inherits", "extend", and "extends".
For example, if you only want to allow the extend keyword,
set the regular expression to /^extend$/.

#### Regular inherit

`css
.gray {
color: gray;
}

.text {
inherit: .gray;
}
`

yields:

`css
.gray,
.text {
color: gray;
}
`

#### Multiple inherit

Inherit multiple selectors at the same time.

`css
.gray {
color: gray;
}

.black {
color: black;
}

.button {
inherit: .gray, .black;
}
`

yields:

`css
.gray,
.button {
color: gray;
}

.black,
.button {
color: black;
}
`

#### Placeholders

Any selector that includes a % is considered a placeholder.
Placeholders will not be output in the final CSS.

`css
%gray {
color: gray;
}

.text {
inherit: %gray;
}
`

yields:

`css
.text {
color: gray;
}
`

#### Partial selectors

If you inherit a selector,
all rules that include that selector will be included as well.

`css
div button span {
color: red;
}

div button {
color: green;
}

button span {
color: pink;
}

.button {
inherit: button;
}

.link {
inherit: div button;
}
`

yields:

`css
div button span,
div .button span,
.link span {
color: red;
}

div button,
div .button,
.link {
color: green;
}

button span,
.button span {
color: pink;
}
`

#### Chained inheritance

`css
.button {
background-color: gray;
}

.button-large {
inherit: .button;
padding: 10px;
}

.button-large-red {
inherit: .button-large;
color: red;
}
`

yields:

`css
.button,
.button-large,
.button-large-red {
background-color: gray;
}

.button-large,
.button-large-red {
padding: 10px;
}

.button-large-red {
color: red;
}
`

#### Media Queries

Inheriting from inside a media query will create a copy of the declarations.
It will act like a "mixin".
Thus, with %placeholders, you won't have to use mixins at all.
Each type of media query will need its own declaration,
so there will be some inevitable repetition.

`css
.gray {
color: gray
}

@media (min-width: 320px) {
.button {
inherit: .gray;
}
}

@media (min-width: 320px) {
.link {
inherit: .gray;
}
}
`

yields:

`css
.gray {
color: gray;
}

@media (min-width: 320px) {
.button,
.link {
color: gray;
}
}
`

#### Substitute for Nested Syntax

Rework doesn't support nested syntax.
However, you can simulate nested syntax with inheritance.

`css
.no-touchevents %link-hover:hover {
text-decoration: underline;
}

a,
button {
inherit: %link-hover;
}
`

yields:

`css
.no-touchevents a:hover,
.no-touchevents button:hover {
text-decoration: underline;
}
``

Thus, you have the features of nested syntax without the nesting.

$3

- You can not inherit a rule that is inside a media query;
you can only inherit rules outside a media query.
If you find yourself in this situation,
just use placeholders instead.
