write theme style more easy!
npm install -g less-plugin-theme-easy
and then on the command line,
lessc file.less --theme-easy
Try the following code
// TODO
@color-font-regular: {
white: #5D6588;
black: #CBD7F0;
}
@color-panel-item-active: {
white: #464e64;
black: #ffffff;
}
.item {
color: theme(@color-font-regular);
background: theme(@color-panel-item-active);
border-color: theme(@color-panel-item-active);
* {
font-size: 12px;
line-height: 30px;
}
&:hover, &.active {
//color: theme(@color-panel-item-active);
background-color: theme({
//color: theme(@color-panel-item
white: #eef4ff;
/*background-color: theme({
white: #eef4ff;*/
black: #19233C;
});
color: theme(@color-font-regular);
/*background-color: theme({
white: #eef4ff;
black: #19233C;
});*/
}
.favorite-icon {
margin-right: 5px;
&.star {
color: theme({
white: #7E9EFD;
black: #5073FF;
});
}
}
}It will be compiled to
.white .item {
color: #5D6588;
background: #464e64;
border-color: #464e64;
}
.black .item {
color: #CBD7F0;
background: #ffffff;
border-color: #ffffff;
}
.item * {
font-size: 12px;
line-height: 30px;
}
.item:hover,
.item.active {
/*background-color: theme({
white: #eef4ff;
black: #19233C;
});*/
}
.white .item:hover,
.white .item.active {
background-color: #eef4ff;
color: #5D6588;
}
.black .item:hover,
.black .item.active {
background-color: #19233C;
color: #CBD7F0;
}
.item .favorite-icon {
margin-right: 5px;
}
.white .item .favorite-icon.star {
color: #7E9EFD;
}
.black .item .favorite-icon.star {
color: #5073FF;
}Then, you can control the global style by adding the desired attributes to your topmost element.
<!--Global Settings style-->
<body class="white">
<div>...</div>
<div class="item">
<a class="favorite-icon">
...
</a>
</div>
</body>If you use the plug-in constructor alone, allow the following parameters to be passed in:
| option | Description | Type | Required | Default |
|---|---|---|---|---|
| themeIdentityKeyWord | The function name keyword to find in the value of the attribute to be replaced. | string | false | 'theme' |
| themePropertyValueHandler | How to replace the attribute | function(option:{key:string;value:string}):string | false | Refer to the following |
| mergeSelector | Whether to combine CSS chunks of the same selector(new option,it is added in 2.0.5+ ) | Boolean | false | true |
Default value of themePropertyValueHandler:
function replace({key, value}) {
return `each(${value}, {
@class: replace(@key, '@', '');
.@{class} & {
${key}: @value;
}
});`
}If mergeSelector = false, the output will be like this, and the same selector css rules will not be merged.

}For example
import LessPluginTheme from 'less-plugin-theme'
new LessPluginTheme({
themeIdentityKeyWord: 'a',
themePropertyValueHandler: ({key,value})=>{return ...},
mergeSelector: true
})If you use it in vue-cli, just add it in the vue.config.js file
const LessThemePlugin = require('less-plugin-theme-easy')
module.exports = {
// ...
css: {
loaderOptions: {
less: {
plugins: [
new LessThemePlugin(/** ...options */),
],
}
}
}
