此CHM文件是偶为了学习方便制作的，去除了原网页中的广告。可以方便的使用索引和搜索。使用索引时要在索引项前加上所属的语言，比如要查找css的padding，就在索引框中输入“css padding”，就可以找到了。网站上的搜索挺麻烦。-The CHM file is even easy to produce in order to learn, in addition to the original web page advertising. Can facilitate the use of indexing and searching. Use the index before the index entry with language belongs, for example, to find the css padding in the index box, enter "css padding" can be found.
