Style Sheet CSS layout experience _ CSS/HTML

Style Sheet CSS layout experience will be added or modified with the accumulation of time. I hope the following things will be helpful or useless to standard learners.

The main content is the differences between IE and MOZILLA and the details that are easy to ignore. The best implementation methods of some classic applications should avoid the violation errors.
