The "first line" in the html page is a series of divs, and each div adopts the float method
Now we need to add a "line" and put in text and other elements. How to make these elements placed on a new line? Instead of following the div!
In fact, you may not know the role of the clear tag. Go to W3C to see the role of the clear tag, and your problem will be solved
Thank you very much!
