Common Browser compatibility

①Block ElementInFloatingTimeHorizontal marginDisplayDouble

② Different browsers display different values for margin and padding.

③ There is a gap between different browser slices

④In UL Li and ol Li, if Li is not floating and the parent label is not set to height, several more pixels may occur in IE6 and IE7.

⑤ IE6 does not support the minimum height

⑥ When IMG is nested in a tag, different colored borders may appear in different browsers:

7 opacity: 0 ~ 1. The smaller the value, the more transparent it is. 1 indicates no transparency, and 0 indicates an hour.

However, ie versions earlier than ie9 (not included) are not supported. filter: alpha (opacity = 50) should be used; the value is 0 ~ 100

 

Summary of bug generation:

 

1. Bugs often appear in IE6

2. Many compatibility problems are unreasonable nesting over tags, and the use of tags is nonstandard.

3.compatibility problems can also be caused by improper use of CSS styles
