You may use some of the same class or ID in multiple sites. If you have a perfect CSS framework, you'll soon be able to read through the code for each of your sites. Don't waste your time reading the code.

3, a better team cooperation
Some companies divide the front-end code of some slightly larger sites into subprojects. Friends who have had such experience should be deeply depressed about this kind of development, pay attention to the common CSS, and pay attention to the code cooperation between each other.
