Rub*_*ain 4 css sass gulp-sass scss-mixins
我想include
在同一个 SCSS 中使用多个。例如:
.section-ptb {
padding-top: 130px;
padding-bottom: 130px;
@include desktop {
padding-top: 80px;
padding-bottom: 80px;
}
@include tablet {
padding-top: 80px;
padding-bottom: 80px;
}
@include mobole {
padding-top: 80px;
padding-bottom: 80px;
}
}

经常使用多个@include 很无聊。有任何方法可以减少代码,我想使用:
.section-ptb {
padding-top: 130px;
padding-bottom: 130px;
@include desktop , @include tablet, @include mobole {
padding-top: 80px;
padding-bottom: 80px;
}
}

但它不是有效的 SCSS。请告诉我另一种减少代码的方法。

你可以使用这样的东西:
社会保障体系
@mixin phone {
@media /*conditions*/ {
@content
}
}
@mixin tablet {
@media /*conditions*/ {
@content
}
}
@mixin desktop {
@media /*conditions*/ {
@content
}
}
@mixin media($keys...) {
@each $key in $keys {
@if ($key == phone) {
@include phone {
@content
}
} @else if ($key == tablet) {
@include tablet {
@content
}
} @else if ($key == desktop) {
@include desktop {
@content
}
}
}
}

用法
@include media(phone, tablet, desktop) {
// your scss code
}
@include media(tablet, desktop) {
// your scss code
}
@include media(phone) {
// your scss code
}
// and so on...

正如@karthick 所提到的,不支持动态包含(目前)。在您的情况下,我认为有一个 mixin 来处理所有媒体查询是有意义的——例如:
社会保障局
// map holding breakpoint values
$breakpoints: (
mobile : 0px,
tablet : 680px,
desktop: 960px
);
// mixin to print out media queries (based on map keys passed)
@mixin media($keys...){
@each $key in $keys {
@media (min-width: map-get($breakpoints, $key)){
@content
}
}
}
.section-ptb {
padding-top: 130px;
padding-bottom: 130px;
// pass the key(s) of the media queries you want to print
@include media(mobile, tablet, desktop){
padding-top: 80px;
padding-bottom: 80px;
}
}
