我想制作一些复合样式值，例如:height:100%-10px;
有什么方法可以用 CSS 做到这一点吗？
或者您是否必须使用 JavaScript？
如果可以，您可以发表您的建议吗？
最佳答案
您将使用 calc() .
height: calc(100% - 10px);
w3.org 8.1. Mathematical Expressions: ‘calc()’
The calc() function allows mathematical expressions with addition (‘+’), subtraction (‘-’), multiplication (‘*’), and division (‘/’) to be used as component values. The ‘calc()’ expression represents the result of the mathematical calculation it contains, using standard operator precedence rules. It can be used wherever , , , , , or values are allowed. Components of a ‘calc()’ expression can be literal values, ‘attr()’ or ‘calc()’ expressions, or values that resolve to one of the preceding types.
