我正在将Bootstrap 4与Webpack一起构建在一个框架上的多站点应用程序。
我想根据body元素上的基类动态更改Bootstrap的某些变量。即:
.class1{
$theme-colours: (
primary: red,
);
}
.class2{
$theme-colours: (
primary: blue,
);
}
然后:
<body class="class1">
<h1 class="text-primary">RED TEXT</h1>
</body>
并且:
<body class="class2">
<h1 class="text-primary">BLUE TEXT</h1>
</body>
在SASS中有可能吗?我尝试使用mixin,但没有成功...
答案 0 :(得分:0)
您必须使用各种Bootstrap 4主题颜色功能/混合器“重建” -primary
类。可以将主要颜色更改放入自定义@mixin
中,从而更容易构建每个主要“主题”:
@mixin build-primary-classes($color) {
@include bg-variant(".bg-primary", $color);
.btn-primary {
@include button-variant($color, $color);
}
.btn-outline-primary {
@include button-outline-variant($color);
}
@include text-emphasis-variant(".text-primary", $color);
.border-primary {
border-color: $color !important;
}
}
.theme1 {
@include build-primary-classes($purple);
}
.theme2 {
@include build-primary-classes($red);
}

再进一步,您可以将“ $ customthemes”放置在地图中,然后生成主题类。
$customthemes: (
"theme1": purple,
"theme2": cyan,
"theme3": orange
);
@each $themeName, $color in $customthemes {
.#{$themeName} {
@include build-primary-classes($color);
}
}

然后,如果您使用的是Webpack,请将$customthemes
映射传递到extract-text-webpack-plugin和SASS-loader。使用data
选项传递$ customthemes ...
webpack-config:
....
use: extractSass.extract({
use: [
{
loader: "sass-loader",
options: {
allChunks: true,
data: '$customthemes:("theme1":purple,"theme2":pink,"theme3":red);'
}
}]
})
.....
请记住,如果$ customthemes过多,则CSS会变得很大。我更喜欢使用SASS生成单独的theme.css
文件,然后根据需要在HTML HEAD中引用任何theme.css
。
