比较p没有设宽度或高度的时候,float是否会失效。 还有哪些情况会失效的?
学习是最好的投资!
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
你所指的失效是什么意思?
目前只知道float在绝对定位和display为none时不生效,其他的还希望大牛们能解答
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.

绝对定位时失效
display:flex时也会失效,可以用margin-left:auto解决
