nested-css

Sass/Less css nesting feature in 90 lines of PHP.

What?

So you can write:

a {
   color: blue;
   .button {
       padding:10px;
       border:1px solid grey;
   }
}

instead of this:

a {
  color: blue;
}

a .button {
  padding: 10px;
  border:1px solid grey;
}

Why?

In my opinion, the way CSS preprocessors handle nesting of child selectors is awesome -- the rest can be easily implemented in any programming language e.g. variables and includes (mixins).
It's much faster than a full implementation of Sass/Less.

How?

Just include the nested-css.php in your project then you can simply do:

$ncss = new NestedCSS();

#### parse nested css
echo $ncss->parse($input);

#### parse then include a .css file
$ncss->include('path/to/some.css');

#### include and cache the result
#### the cache system automatically refreshes
#### the cache once you make a change
$ncss->include('path/to/some.css',true);

Future?

We are using this library in production at SunSed.com so if you find a bug and submit it, we will fix it very quickly.

Todos:

Add helper functions for handling colors and px calculations like in Sass.
Try to see if you can improve compiler speed.
Support for composer.

Licence?

Known Bugs?

Your nesting should be clean or it will fail compiling it correctly.

For example:

p {
    color: blue;
    .red{
        color: red;
    }
    font-family: arial;
}

To keep nested-css compiler fast we keep it's internal very simple and instead of making it smarter/slower, we think it's better to put the burden on the programmer. So instead, please nest your CSS selectors like this:

p {
    color: blue;
    font-family: arial;
    .red{
        color: red;
    }
}
