当您想要修改函数范围之外的变量时,是否有针对该情况的解决方法? :
$ui-theme: 'pink';
@if $ui-theme == "pink" {
$ui-main: #eb82b0;
$ui-secondary: #fff5f9;
$ui-third: #f6c2d9;
} @else {
$ui-main: #ff8067;
$ui-secondary: #fff6e5;
$ui-third: #ffb1a2;
}
a { color: $ui-main; background: $ui-secondary };
我想创建一个名为ui-theme
的全局变量,它将在定义下面的所有其他代码中定义$ui-main, $ui-secondary...
。似乎在使用@if
等指令时也会应用变量范围。
有谁知道如何实现这一目标?

您必须在控制块之外初始化变量:
$ui-theme: 'pink';
$ui-main: null;
$ui-secondary: null;
$ui-third: null;
@if $ui-theme == "pink" {
$ui-main: #eb82b0;
$ui-secondary: #fff5f9;
$ui-third: #f6c2d9;
} @else {
$ui-main: #ff8067;
$ui-secondary: #fff6e5;
$ui-third: #ffb1a2;
}
a { color: $ui-main; background: $ui-secondary };
输出:
a {
color: #eb82b0;
background: #fff5f9;
}
通过@include
进行主题化而不是像这样的硬编码变量可能更好。
_pink.scss:
$ui-main: #eb82b0;
$ui-secondary: #fff5f9;
$ui-third: #f6c2d9;
styles.scss:
@include "pink"; // or don't include anything if you want the default colors
$ui-main: #ff8067 !default;
$ui-secondary: #fff6e5 !default;
$ui-third: #ffb1a2 !default;
a { color: $ui-main; background: $ui-secondary };
