This edition of the PHP Manual allows users to choose from skins to display the contents, as well as develop custom skins to meet some special needs. We decided to support skins because we realized that one skin cannot satisfy everybody's needs in a such heavily used edition.
We included two skins by default inside the CHM. These cannot be modified or removed, so if you have the CHM, you have these two skins inside. The Low skin is optimized for small window display, the High skin is a variation of the Low one with some graphics added to spice it up.
Note that though the current skin development methods are quite final, there may be heavy changes in used CSS classes or page elements while we refine the skin development ideas. As this edition is currently in development stage, the information described herein is not to be considered completely stable.
