如何阅读这个LESS CSS？ [英] How to read this LESS css?

问题描述

我想弄清楚Joni Korpi的无框架CSS无框架网格（ http://framelessgrid.com/ ）和我有一个很难读的.less文件他有。我有一个基本的了解，LESS使用变量，所以我知道column = 48和gutter = 24，这是关于它。

I am trying to figure out Joni Korpi's Frameless CSS frameless grid (http://framelessgrid.com/) and I'm having a hard time reading the .less file he has. I have a basic understanding that LESS uses variables so I know column = 48 and gutter = 24 and that's about it.

是否1cols = 1 *（48 + 24） - 24）/ 12？

Does 1cols = 1 * (48 + 24) - 24)/ 12 ?

t理解是 @ 1col：@ 1cols; 和 .width（@cols：1）{
width：（@cols * column + @gutter） - @gutter）/ @em;
}

有人可以帮助吗？

https://github.com/jonikorpi/Frameless/blob/master/frameless.less

@font-size: 16;         // Your base font-size in pixels
@em: @font-size*1em;    // Shorthand for outputting ems, e.g. "12/@em"

@column: 48;    // The column-width of your grid in pixels
@gutter: 24;    // The gutter-width of your grid in pixels


//
// Column-widths in variables, in ems
//

 @1cols: ( 1 * (@column + @gutter) - @gutter) / @em; @1col: @1cols;
 @2cols: ( 2 * (@column + @gutter) - @gutter) / @em;
 @3cols: ( 3 * (@column + @gutter) - @gutter) / @em;
 @4cols: ( 4 * (@column + @gutter) - @gutter) / @em;
 @5cols: ( 5 * (@column + @gutter) - @gutter) / @em;
 @6cols: ( 6 * (@column + @gutter) - @gutter) / @em;
 @7cols: ( 7 * (@column + @gutter) - @gutter) / @em;
 @8cols: ( 8 * (@column + @gutter) - @gutter) / @em;
 @9cols: ( 9 * (@column + @gutter) - @gutter) / @em;
@10cols: (10 * (@column + @gutter) - @gutter) / @em;
@11cols: (11 * (@column + @gutter) - @gutter) / @em;
@12cols: (12 * (@column + @gutter) - @gutter) / @em;
@13cols: (13 * (@column + @gutter) - @gutter) / @em;
@14cols: (14 * (@column + @gutter) - @gutter) / @em;
@15cols: (15 * (@column + @gutter) - @gutter) / @em;
@16cols: (16 * (@column + @gutter) - @gutter) / @em;


//
// Column-widths in a function, in ems
//

.width (@cols:1) {
width: (@cols * (@column + @gutter) - @gutter) / @em;
}

推荐答案

@ 1cols 等只是变量名。 少于中的变量名称允许以数字开头。

@1cols etc are just variable names. Variable names in less are allowed to start with numbers.

@1col: @1cols;

这就是说变量 @ 1col 等于之前设置的变量 @ 1cols 。大概是1col，因为1是单数，但其他是复数，所以它只是让你选择使用 @ 1col 或 @ 1cols

That's just making the saying that variable @1col equals the variable @1cols set earlier. Presumably, "1col" because 1 is singular, but the others are plural, so it just gives you the option of using either @1col or @1cols both of them being the same value.

@1cols: ( 1 * (@column + @gutter) - @gutter) / @em;

这只是数学。如果你想要一个3列宽的部分，这是（列宽+格槽宽度）减去一个gutter的3倍。

That's just math. If you want a section that's 3 columns width, that's 3 times the (column width + gutter width) minus one gutter.

.width (@cols:1) {
width: (@cols * (@column + @gutter) - @gutter) / @em;
}

这是一个mixin函数， 1.你可以这样使用它：

That's a mixin function that takes a variable number of columns with a default parameter of 1. You can use it like this:

.my-class{
   .width(3);
}
/* these two are identical */
.my-class{
   width: @3cols;
}

第一种方法的好处是可以替换 3 使用变量，以便您可以在其他位置使用它。

The benefit of the first method is that you can replace 3 with a variable so you can use it elsewhere.
