The last time I demonstrated the effect of div to others, I wrote a css style but it could not be rendered. Finally, I accidentally found that when I was writing a css style, I named a class a name starting with a number. I remembered that I also had this problem when I was just learning style sheets last year. I finally solved it by stating that the name in CSS should not start with a number, but preferably a letter.
The following is: CSS naming convention
XHTML-CSS writing recommends that all lowercase attribute values in xhtml code must be enclosed in double quotes ("") up, and must have a value. Each tag must have a beginning and an end, and must have the correct level. Empty elements must have an ending tag or add "/" after the beginning tag. The performance is completely separated from the structure, and there is no need in the code. Any expression elements involved, such as style, font, bgColor, border, etc. The definitions from
to should follow the principle from large to small to reflect the structure of the document and facilitate search engine queries. Add a unique, structural tag ID to each table and form. Add comments to important blocks, such as: Add alt tags to images. All tags must be properly nested. There must be an element before the root element to declare its use. Which DTD root element must have the xmlns attribute to specify the namespace of http://www.w3.org/1999/xhtml
During this period, I did some research on CSS naming due to work needs, mainly to create documents Such standards can make it easier for people to understand and understand.
