推荐答案
指定CSS单位是非零值的要求。浏览器可能会尝试猜测你的意思，但它仍然是一个破碎的样式表根据标准。
Specifying CSS units is a requirement for non-zero values. Browsers may try to guess what you meant, but it would still be a broken stylesheet according to the standard.
在CSS2中没有默认单位，只是浏览器可能会尝试帮助你，虽然它可能会忽略你的语句，没有指定单位作为一个无效的。
I.e. there is no "default unit" in CSS2, it's just that the browser may try to help you out, although it may as well just ignore your statement that doesn't specify units as an invalid one.
