Comma in CSS, multiple selectors using the same CSS

csscss-selectors

提问by nothrow

.Resource table.Tbl td
{ /* some css*/ }

.Resource table.Tbl td.num
{ /* some css 2*/ }

.Resource table.Tbl td.num span.icon
{ /* some css 3*/ }

.Resource table.Tbl2 td
{ /* some css*/ }

.Resource table.Tbl2 td.num
{ /* some css 2*/ }

.Resource table.Tbl2 td.num span.icon
{ /* some css 3*/ }

where the CSS for Tbl and Tbl2 should be the same.

Tbl 和 Tbl2 的 CSS 应该相同。

.Resource table.Tbl, table.Tbl2 td { /* some css*/ }

doesn't work.

不起作用。

How can I achieve this, without duplicating whole line?

如何在不复制整行的情况下实现这一目标?

回答by Alin Purcaru

.Resource table.Tbl td, .Resource table.Tbl2 td { /* some css*/ }

You should add the full ancestor path for both rules. Not just where you see differences.

您应该为这两个规则添加完整的祖先路径。不仅仅是你看到差异的地方。

.Resource table.Tbl td, .Resource table.Tbl2 td { /* some css */ }

You have to duplicate the stuff before and after table.TblX, because there's no way to group the ,operator to have higher precedence than the descendent selector ?.

您必须在 之前和之后复制内容table.TblX,因为无法将,运算符分组以使其具有比后代选择器更高的优先级?

You can't (well not on every browser, read on).

你不能(当然不是在每个浏览器上,请继续阅读)。

Each selector is independent, unfortunately.

不幸的是,每个选择器都是独立的。

It is one of CSS's annoying issues.

这是CSS 令人讨厌的问题之一

There is :any(), which can do what you wish, but browser support is limited.

:any(),它可以做你想做的,但浏览器支持是有限的。

You can do it anyway you like and pre-process it with a server side language, so it outputs independent selectors.

您可以随心所欲地执行此操作,并使用服务器端语言对其进行预处理,因此它会输出独立的选择器。
