`{visible modifier}.{state}`

```
@textbox selected.active {
    background: #003642;
    foreground: #008ed4;
}
```

Sets all selected textboxes marked active to the given foreground and background color.

# File structure

The file is structured as follows

```
/* Global properties, that apply as default to all widgets. */
{list of properties}

@{class} {optional state} {
    {list of properties}
}
@{name}.{name} {optional state} {
    {list of properties}
}
```

The global properties an freeĺy be mixed between entries.

Each property is constructed like:
```
{key} : {value} ;
```
Key is a simple ascii string.
Separated from value by a colon ':';
Value supports the following formats:

 * string:  `"{string}"`
 * integer: `[0-9]+`
 * double:  `[0-9]+\.[0-9]`
 * boolean: `true|false`
 * color:
    * `#[0-9a-fA-F]{6}`: hexidecimal rgb color.
    * `#[0-9a-fA-F]{8}`:  hexidecimal argb color.
    * `argb:[0-0a-fA-F]{8}`: Old **rofi** argb color style.
    * `rgba\([0-9]{1,3},[0-9]{1,3}, [0-9]{1,3}, {double}\)`: css style rgba color.
    * `rgb\([0-9]{1,3},[0-9]{1,3}, [0-9]{1,3}\)`: css style rgb color.

Each property is closed by a semi-colon `;`;
