Answer 1

Two notes

1. You need to have content to :before / :after pseudo elements
2. You have forgotten the unprefixed version: transform: rotate(45deg) scale(1);

Answer 2

将此规则添加到元素：“ display：inline-block;”

Answer 3

You need to include the standard, non-prefixed version (ie transform: rotate(45deg) scale(1); ) as the final definition in your list of transforms. The -moz one is deprecated, as will/should be the other ones in time. See the MDN for reference .
