Complex classes like Style often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use Style, and based on these observations, apply Extract Interface, too.

||
| 1588 | are sufficient [helpers var $_important_props, __construct(), important_set(), important_get()] |
||
| 1589 | |||
| 1590 | Only for combined attributes extra treatment needed. See below. |
||
| 1591 | |||
| 1592 | div { border: 1px red; } |
||
| 1593 | div { border: solid; } // Not combined! Only one occurence of same style per context |
||
| 1594 | // |
||
| 1595 | div { border: 1px red; } |
||
| 1596 | div a { border: solid; } // Adding to border style ok by inheritance |
||
| 1597 | // |
||
| 1598 | div { border-style: solid; } // Adding to border style ok because of different styles |
||
| 1599 | div { border: 1px red; } |
||
| 1600 | // |
||
| 1601 | div { border-style: solid; !important} // border: overrides, even though not !important |

||
| 1606 | |||
| 1607 | Special treatment: |
||
| 1608 | At individual property like border-top-width need to check whether overriding value is also !important. |
||
| 1609 | Also store the !important condition for later overrides. |
||
| 1610 | Since not known who is initiating the override, need to get passed !important as parameter. |
||
| 1611 | !important Paramter taken as in the original style in the css file. |
||
| 1612 | When property border !important given, do not mark subsets like border_style as important. Only |
||
| 1613 | individual properties. |
||
| 1614 | |||
| 1615 | Note: |
||
| 1616 | Setting individual property directly from css with e.g. set_border_top_style() is not needed, because |
