CSS 规范中定义了一些保留关键字,我们应该在 <custom-ident>
中避免使用这些值。历史遗留原因,虽然当前某些浏览器支持这些值,但在将来可能会禁用,这会导致相关 CSS 失效。
TODO: CSS 示例
详见:
这些关键字当前散落在不同的规范,包括:
css-values-4
https://www.w3.org/TR/css-values-4/#common-keywords
Defined:
initial
inherit
unset
css-cascade-4
https://drafts.csswg.org/css-cascade/#defaulting-keywords
Defined:
initial
inherit
unset
revert
css-cascade-5
https://drafts.csswg.org/css-cascade-5/#revert-layer
Defined:
initial
inherit
unset
revert
revert-layer
css-values-4
https://www.w3.org/TR/css-values-4/#ref-for-css-wide-keywords
The CSS-wide keywords are not valid
<custom-ident>
s. Thedefault
keyword is reserved and is also not a valid<custom-ident>
There is a default
keyword.
