Selectors may be combined in many ways to achieve great specificity and flexibility. Multiple selectors may be joined in a spaced list to specify elements by location, element type, id, class, or any combination thereof. The order of the selectors is important. For example, applies to all elements of class
that are inside div elements, whereas applies to all div elements that are in elements of class
will specify the box dimensions of each block belonging to '
'. Moreover, each such box will have total height 160px and width 260px, which is the sum of the content, padding, border and margin.
In Objective-C, classes and protocols can be forward-declared if you only need to use them as part of an object pointer type, e.g.
* or id
. This is especially useful inside class definitions, e.g. if a class contains a member that is a pointer to another class; to avoid circular references (i.e. that class might also contain a member that is a pointer to this class), we simply forward-declare the classes instead.
