Benefits: Separating the data from the display Reduce network traffic Make the entire site visually consistent Increased development efficiency (reduced coupling, one person is responsible for writing HTML, one person is responsible for writing CSS) For example, there is a style that needs to be displayed on 100 pages, if it is HTML to implement, then write 100 times, now have CSS, just write it again. Now, HTML provides only data and some controls, completely giving C
