ie与firefox的css兼容问题（CSS compatibility issues with IE and Firefox） CSS has a high value for browser compatibility, and IE and Firefox typically have a lot of parsing differences. Heres the compatibility point. Common compatibility issues: 1.DOCTYPE affects CSS processing 2.FF: div sets margin-left, margin-right is auto, centered, IE not When 3.FF: body sets text-align, div needs to set the margin: auto (mainly margin-left, margin-right) to be centered After 4.FF: sets padding, div adds height and width, but IE doesnt, so it needs to be used.
