css - 我如何在 CSS 中执行 "margin : width : height : auto; "？

Question

我测试了它，确实有效。无论如何我可以为许多属性分配一个值。

Answer 1

没有办法用简单的 CSS 做到这一点。但是还有其他选择，例如 Less CSS允许您执行此操作以及更多操作。

引用自 Less css 网站:

LESS extends CSS with dynamic behavior such as variables, mixins, operations and functions. LESS runs on both the client-side (IE 6+, Webkit, Firefox) and server-side, with Node.js.

更新:添加Sass感谢@Michael Mior

引自网站:

Sass makes CSS fun again. Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It’s translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.
