如何防止 Less 尝试编译 CSS calc() 属性? [英] How to prevent Less from trying to compile CSS calc() properties?

问题描述

我正在使用的 Less 编译器(OrangeBits 和 dotless 1.3.0.5) 正在积极翻译

The Less compilers that I'm using (OrangeBits and dotless 1.3.0.5) are aggressively translating

body { width: calc(100% - 250px - 1.5em); }

进入

body { width: calc(-151.5%); }

这显然不是我们想要的.我想知道是否有办法向 Less 编译器发出信号，以便在编译期间基本上忽略该属性.我搜索了 Less 文档和两个编译器的文档，但找不到任何内容.

Which is obviously not desired. I'm wondering if there is a way to signal to the Less compiler to essentially ignore the attribute during compilation. I've searched through the Less documentation and both compilers' documentation, and I could not find anything.

Less 或 Less 编译器是否支持这一点?

Does Less or a Less compiler support this?

如果没有，是否有 CSS 扩展器可以实现?

If not, is there a CSS extender that does?

推荐答案

Less 默认不再计算 calc 中的表达式，因为 v3.00.

Less no longer evaluates expression inside calc by default since v3.00.

原始答案(Less v1.x...2.x):

这样做:

body { width: calc(~"100% - 250px - 1.5em"); }

在 Less 1.4.0 中，我们将有一个 strictMaths 选项，该选项要求所有 Less 计算都在括号内，因此 calc 将out-of-the-"盒子".这是一个选项，因为它是一个重大的突破性变化.默认情况下，1.4.0 的早期测试版启用了此选项.发布版本默认关闭.

In Less 1.4.0 we will have a strictMaths option which requires all Less calculations to be within brackets, so the calc will work "out-of-the-box". This is an option since it is a major breaking change. Early betas of 1.4.0 had this option on by default. The release version has it off by default.
