Common minor problems when using CSS

1. margin-bottom of the Margin-top and last element of the first child element

Workaround:

1) parent Element plus border

2) parent element plus padding

3) Parent Element Overflow:hidden

4) Add the pre-built content for the parent element. Parent:before {conent: '; display:table;}

2. Child elements are all floating, the parent element loses height

Workaround:

1) parent Element Overflow:hidden

2) next element Clear:both;

3) The parent element adds a post-built content generation:. parent:after {conent: '; display:table; clear:both;}
