- !important attribute
- For basic functionality of the !important attribute with overloading

- are sufficient [helpers var $_important_props, __construct(), important_set(), important_get()]
- Only for combined attributes extra treatment needed. See below.

- div { border: solid; } // Not combined! Only one occurence of same style per context
- //
- div { border: 1px red; }
- div a { border: solid; } // Adding to border style ok by inheritance

- div { border: 1px red; }

- div { border-style: solid; !important} // border: overrides, even though not !important
- div { border: 1px dashed red; }
- //
- div { border: 1px red; !important }
- div a { border-style: solid; } // Need to override because not set
- Special treatment:
- At individual property like border-top-width need to check whether overriding value is also !important.
- Also store the !important condition for later overrides.
- Since not known who is initiating the override, need to get passed !important as parameter.
- !important Paramter taken as in the original style in the css file.
- When property border !important given, do not mark subsets like border_style as important. Only
- individual properties.
- Note:
- Setting individual property directly from css with e.g. set_border_top_style() is not needed, because
- missing set funcions handled by a generic handler __set(), including the !important.
- Setting individual property of as sub-property is handled below.
