With my love for ASP.NET front-end development, I looked at the float attribute this morning. To be honest, it is quite complicated.
Let me give you my example first. My self-understanding is all in this example. There are still some imperfections, the clear attribute is not put up.

元素占用的空间有div块级(block),span行内级(inline)之分。block,占用一行空间,撑满父元素;inline,占用的空间仅仅是自身content padding border margin。
要知道block,inline,都有float属性,即浮动。不设置浮动属性,默认float为none。
哥哥属性设置浮动后,其弟弟元素的内容包围哥哥元素,哥哥元素不再属于父元素。
弟弟元素设置浮动后,对哥哥元素没影响,但同样不属于父元素。
