你好!p没有设宽或高时,若里面也没有任何占宽高元素或文字内容,则该p不显示,但float仍生效。
失效情况:两个同级p,第一个设置float:left,第二个未设置,则会第一个脱离了文档流,也就是说第二个p无视第一个的存在,将与之发生重叠

Properties not affecting flexible boxes
Because flexible boxes use a different layout algorithm, some
properties do not make sense on a flex container:
column-* properties of the multiple column module have no effect on a flex item.
float and clear have no effect on a flex item. Using float causes the display property of the element to compute to block.
vertical-align has no effect on the alignment of flex items.
