我在SASS创建了@mixin为我做媒体查询;
@mixin break($bp1, $minmax:minmax, $media:screen, $bp2:null){
@if $minmax == "minmax" and variable-exists(bp1) and $bp2{
@media #{$media} and (min-width: $bp1) and (max-width: #{$bp2 - 1px}){
@content;
}
} @else if $minmax == "min" and variable-exists(bp1){
@media #{$media} and (min-width: $bp1){
@content;
}
} @else if $minmax == "max" and variable-exists(bp1){
@media #{$media} and (max-width: #{$bp1 - 1}){
@content;
}
}
}
工作完美,但我想在@media查询 - 字符串之后添加另一部分(宽高比,方向等),就在整个创建的查询之后。我努力了,但它一直在说: 发现意外的令牌SASS_VAR 或类似的东西。
代码如下:
@mixin break($bp1, $minmax:minmax, $media:screen, $after:null, $bp2:null){
@if $minmax == "minmax" and variable-exists(bp1) and $bp2{
@media #{$media} and (min-width: $bp1) and (max-width: #{$bp2 - 1px}) #{$after}{
@content;
}
} @else if $minmax == "min" and variable-exists(bp1){
@media #{$media} and (min-width: $bp1){
@content;
}
} @else if $minmax == "max" and variable-exists(bp1){
@media #{$media} and (max-width: #{$bp1 - 1}){
@content;
}
}
}
这是我第一次与SASS合作。我读过有关内置CSS3 @mixins的内容 我已经习惯了PHP,就像
一样echo "@media ... and () .." . $after;
我该怎么办?谢谢:))
新的mixin看起来不错,但我希望最后一个参数是可选的,所以我不想要硬编码"和#34;
答案 0 :(得分:0)
@mixin break($bp1, $minmax: minmax, $media: screen, $bp2: null, $after: null) {
@if $minmax == "minmax" and variable-exists(bp1) and $bp2 {
@media #{$media} and (min-width: $bp1) and (max-width: calc(#{$bp2} - 1)) and (#{$after}){
@content;
}
}
}
@include break(100, 'minmax', 'all', 200, 'aspect-ratio: 1') {
display: none;
}
产生
@media all and (min-width: 100) and (min-width: calc(200 - 1)) and (aspect-ratio: 1) {
display: none;
}
