我創建了一個 mixin css 檔案
//Breakpoint
@media (min-width: 64em) {
//styles go here
}
//640px, 1024px, 1400px
$breakpoints-up: ("medium": "40em", "large": "64em", "xlarge": "87.5em");
// 639px, 1023px, 139px
$breakpoints-down: ("small": "39.9375em", "medium": "63.9375em", "large": "87.4375em");
@mixin breakpoint-up($size) {
@media (min-width: map-get($breakpoints-up, $size)) {
@content;
}
}
@mixin breakpoint-down($size) {
@media (max-width: map-get($breakpoints-down, $size)) {
@content;
}
}然后我嘗試在我的全域 css 檔案中實作它
.hide-for-mobile {
//Hide for tab and mobile
@include breakpoint-down(medium) {
display: none;
}
}
.hide-for-desktop {
//hide for desktop
@include breakpoint-up(large) {
display: none;
}
}盡管全域和混合檔案是我的主 css 檔案中匯入的一部分
@import "globals";
@import "mixins";
@import "variables";
@import "headers";最后它給出了錯誤
Compilation Error
Error: no mixin named breakpoint-down
on line 63 of sass/c:\Users\USER\Downloads\Project\app\scss\_globals.scss
from line 1 of sass/c:\Users\USER\Downloads\Project\app\scss\style.scss
>> @include breakpoint-down(medium) {uj5u.com熱心網友回復：
我相信問題可能在于globals您在匯入mixins. 正因為如此，在呼叫 globals 時，還沒有一個叫做 的混合breakpoint-down：它還沒有被定義。要修復它，您可能只需要切換匯入
@import "mixins"; // First instead of second
@import "globals";
@import "variables";
@import "headers";
希望這有幫助:)
