瀑布流布局在商城类、文章类 app、网页中都是常用的，使用这样的形式，能过让整个页面更加的活波，也能让图片根据实际的大小来显示，更好的展示图片内容。那么代码如何实现呢

实现的效果

代码

<template>
	<view class="container">
		<view class="queue" v-for="i in 4">
			<view class="item" v-for="j in 8"> 
				
				
			</view>
		</view>
	</view>
</template>

<script>

	export default {
		data() {
			return {
				
			};
		},
		onLoad() {
			
		},
		methods:{
		
		}
	}
</script>

<style lang="scss">
	
	$lineCount: 4;
	$count: 8;
	
	@function randomNum($max, $min: 0, $u: 1) {
	    @return ($min + random($max)) * $u;
	}
	
	@function randomColor() {
	    @return rgb(randomNum(255), randomNum(255), randomNum(255));
	}
	
	.container {
	    display: flex;
	    flex-direction: row;
	    justify-content: space-between;
	    overflow: hidden;
	}
	
	.queue {
	    display: flex;
	    flex-direction: column;
	    flex-basis: 24%;
	
	}
	
	.item {
	    position: relative;
	    width: 100%;
	    margin: 2.5% 0;
	}
	
	@for $i from 1 to $lineCount+1 {
	    .queue:nth-child(#{$i}) {
	        @for $j from 1 to $count+1 {
	            .item:nth-child(#{$j}) {
	                height: #{randomNum(300, 50)}px;
	                background: randomColor();
	
	                &::after {
	                    content: "#{$j}";
	                    position: absolute;
	                    color: #fff;
	                    font-size: 24px;
	                    top: 50%;
	                    left: 50%;
	                    transform: translate(-50%, -50%);
	                }
	            }
	        }
	    }
	}
	
</style>

其中下面代码部分是scss

	$lineCount: 4;
	$count: 8;
	
	@function randomNum($max, $min: 0, $u: 1) {
	    @return ($min + random($max)) * $u;
	}
	
	@function randomColor() {
	    @return rgb(randomNum(255), randomNum(255), randomNum(255));
	}
	@for $i from 1 to $lineCount+1 {
	    .queue:nth-child(#{$i}) {
	        @for $j from 1 to $count+1 {
	            .item:nth-child(#{$j}) {
	                height: #{randomNum(300, 50)}px;
	                background: randomColor();
	
	                &::after {
	                    content: "#{$j}";
	                    position: absolute;
	                    color: #fff;
	                    font-size: 24px;
	                    top: 50%;
	                    left: 50%;
	                    transform: translate(-50%, -50%);
	                }
	            }
	        }
	    }
	}
