CSS干货(不定时更新)

文章涉及scss的知识,可参考Scss笔记

清除浮动

@mixin clearfix {
    &:after{
        content: "";
        display: block;
        clear: both;
        visibility: hidden;
        line-height: 0;
        height: 0;
    }    
}

去除数字输入框上下选择按钮

input[type="number"] {
    &::-webkit-outer-spin-button, &::-webkit-inner-spin-button {
        -webkit-appearance: none;
    }
    -moz-appearance: textfield;
}

超出省略

@mixin ellipsis($line: 1) {
    overflow: hidden;
    @if $line > 1 {
        display: -webkit-box;
        -webkit-box-orient: vertical;
        -webkit-line-clamp: $line;
    } @else {
        text-overflow: ellipsis;
        white-space: nowrap;
    }
}

解决ios使用overflow: scroll卡顿

-webkit-overflow-scrolling: touch;

去除ios输入框阴影

input {
    -webkit-appearance: none;
}

识别\n并成功换行

white-space: pre-line;

浮动排列

@mixin sequence($space, $num) {
  $size: percentage(1 / $num);
  width: calc(#{$size} - #{$space} * #{$num - 1} / #{$num});
  float: left;
  margin-top: $space;
  margin-right: $space;
  &:nth-child(-n+#{$num}) {
    margin-top: 0;
  }
  &:nth-child(#{$num}n) {
    margin-right: 0;
  }
}

底部安全区域

@mixin safearea($distance: 0px, $selector: padding-bottom) {
  #{$selector}: $distance;
  #{$selector}: calc(#{$distance} + constant(safe-area-inset-bottom));
  #{$selector}: calc(#{$distance} + env(safe-area-inset-bottom));
}
