CSS refers to Cascading Style Sheets
1. Padding and margin have four attributes: up, right, bottom, left, and there are four abbreviation methods, one of which is:
property:value1 value2 value3 表示的意思是 top 值是value,right和left的值是value2,bottom的值是
value3
2. Background Not to mention the attributes of the background, one of the attributes is background-attachment: fixed; As the rest of the page scrolls, the background image does not move.
It should attract the attention of beginners
3. Wildcards in the selector*
4、. Class selector #id selector, id selector name is unique.
