问题描述

我想用 CSS 构建一个80 年代 TRON 网格"效果，但在将它放到我想要的地方时遇到了一些问题.

像

我的要求:

将一侧淡化为透明
把它打包成一个漂亮的 .class 放在任何 <element> 上就可以了

<小时>

我用 2 种不同的技术对此进行了 2 次尝试.

80 年代 Grid #1(伪选择器)

虽然这很有效，但每次我想要效果时在我的 html 中放置 10 个 <div> 并不理想.

body { 背景:黑色；}.grid-container {位置:绝对；宽度:200%；高度:100vh；底部:0；左:-50%；溢出:隐藏；变换:透视(200px)旋转X(40度)缩放(1)平移Z(0)；变换原点:底部；填充:1px；-webkit-background-clip:内容框；-webkit-backface-visibility:隐藏；轮廓:1px纯透明；will-change:变换；}.grid-line { 高度:100%;宽度:100%；位置:绝对；}.grid-line:之前，.grid-line:after { content: "";显示:块；位置:绝对；}.grid-line:before { 高度:5px;宽度:100%；背景:蓝色；}.grid-line:after { height: 100%;宽度:5px；背景图像:线性渐变(透明，蓝色)；}.grid-line:nth-child(1):before { top: 0%;不透明度:0；}.grid-line:nth-child(2):before { top: 10%;不透明度:0；}.grid-line:nth-child(3):before { top: 20%;不透明度:0.3；}.grid-line:nth-child(4):before { top: 30%;不透明度:0.4；}.grid-line:nth-child(5):before { top: 40%;不透明度:0.5；}.grid-line:nth-child(6):before { top: 50%;不透明度:0.6；}.grid-line:nth-child(7):before { top: 60%;不透明度:0.7；}.grid-line:nth-child(8):before { top: 70%;不透明度:0.8；}.grid-line:nth-child(9):before { top: 80%;不透明度:0.9；}.grid-line:nth-child(10):before { top: 90%;不透明度:1；}.grid-line:nth-child(11):before { top: calc(100% - 3px);}.grid-line:nth-child(1):after { left: 0%;}.grid-line:nth-child(2):after { left: 10%;}.grid-line:nth-child(3):after { left: 20%;}.grid-line:nth-child(4):after { left: 30%;}.grid-line:nth-child(5):after { left: 40%;}.grid-line:nth-child(6):after { left: 50%;}.grid-line:nth-child(7):after { left: 60%;}.grid-line:nth-child(8):after { left: 70%;}.grid-line:nth-child(9):after { left: 80%;}.grid-line:nth-child(10):after { left: 90%;}.grid-line:nth-child(11):after { left: calc(100% - 3px);}

80 年代网格 #2(线性渐变)
https://codepen.io/oneezy/pen/OaQNPe
这种技术非常理想，因为它允许我在 1 个 <element> 上使用 1 个 .class，但我不知道如何使它淡出.

body { 背景:黑色；}.grid-container { 宽度:100%;位置:绝对；底部:0；左:0；}.grid-container:在 {变换:透视(200px)旋转X(40度)缩放(2,1)平移Z(0)；内容: "";显示:块；位置:绝对；底部:0；左:0；右:0；宽度:100%；高度:100vh；填充:1px；-webkit-background-clip:内容框；-webkit-backface-visibility:隐藏；轮廓:1px纯透明；变换原点:底部中心；will-change:变换；}.grid-container:在 {背景位置:中心底部；背景尺寸:40px 40px；背景图:线性渐变(向右，蓝色 1px，透明 0)，线性渐变(到底部，蓝色 3px，透明 0)；}

<section class="grid-container"></section>

提前感谢您的建议:D

解决方案

您可以使用带有 alpha 渐变的 mask-image 来实现您想要的效果.

.grid-container:after {-webkit-mask-image: -webkit-gradient(linear, left 90%, left top, from(rgba(0,0,0,1)), to(rgba(0,0,0,0)));掩码图像:渐变(线性，左 90%，左上角，从(rgba(0,0,0,1))，到(rgba(0,0,0,0)))；}

I'm wanting to build an "80's TRON Grid" effect with CSS but I'm running into a few issues with getting it where I want it.

Stuff like this.

My Requirements:

Fade 1 side to transparent
Package it up into a nice .class to put on any <element> and it just work

I've made 2 attempts at this w/ 2 different techniques.

80's Grid #1 (pseudo selectors)
https://codepen.io/oneezy/pen/MPQWBE
Although this works perfectly, it's not ideal to put 10 <div>'s in my html every time I want the effect.

body { background: black; }

.grid-container { 
	position: absolute; width: 200%; height: 100vh; bottom: 0; left: -50%; overflow: hidden; 
	transform: perspective(200px) rotateX(40deg) scale(1) translateZ(0);
	transform-origin: bottom;
	padding: 1px; 
	-webkit-background-clip: content-box; 
	-webkit-backface-visibility: hidden;
	outline: 1px solid transparent; 
	will-change: transform; 
}

.grid-line { height: 100%; width: 100%; position: absolute; }


.grid-line:before,
.grid-line:after  { content: ""; display: block; position: absolute; }
.grid-line:before { height: 5px; width: 100%; background: blue; }
.grid-line:after  { height: 100%; width: 5px; background-image: linear-gradient(transparent, blue); }

.grid-line:nth-child(1):before  { top: 0%;  opacity: 0; }
.grid-line:nth-child(2):before  { top: 10%; opacity: 0; }
.grid-line:nth-child(3):before  { top: 20%; opacity: .3; }
.grid-line:nth-child(4):before  { top: 30%; opacity: .4; }
.grid-line:nth-child(5):before  { top: 40%; opacity: .5; }
.grid-line:nth-child(6):before  { top: 50%; opacity: .6; }
.grid-line:nth-child(7):before  { top: 60%; opacity: .7; }
.grid-line:nth-child(8):before  { top: 70%; opacity: .8; }
.grid-line:nth-child(9):before  { top: 80%; opacity: .9; }
.grid-line:nth-child(10):before { top: 90%; opacity: 1; }
.grid-line:nth-child(11):before { top: calc(100% - 3px); }


.grid-line:nth-child(1):after  { left: 0%;  }
.grid-line:nth-child(2):after  { left: 10%; }
.grid-line:nth-child(3):after  { left: 20%; }
.grid-line:nth-child(4):after  { left: 30%; }
.grid-line:nth-child(5):after  { left: 40%; }
.grid-line:nth-child(6):after  { left: 50%; }
.grid-line:nth-child(7):after  { left: 60%; }
.grid-line:nth-child(8):after  { left: 70%; }
.grid-line:nth-child(9):after  { left: 80%; }
.grid-line:nth-child(10):after { left: 90%; }
.grid-line:nth-child(11):after { left: calc(100% - 3px); }

<section class="grid-container">
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div> 
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
	<div class="grid-line"></div>
</section>

80's Grid #2 (linear-gradient)
https://codepen.io/oneezy/pen/OaQNPe
This technique is ideal because it allows me to use 1 .class on 1 <element>, but I'm not sure how to make it fade out.

body { background: black; }

.grid-container { width: 100%; position: absolute; bottom: 0; left: 0; }

.grid-container:after { 
  
	transform: perspective(200px) rotateX(40deg) scale(2,1) translateZ(0);
  content: ""; display: block; position: absolute; bottom: 0; left: 0; right: 0; width: 100%; height: 100vh;
  padding: 1px; 
  -webkit-background-clip: content-box; 
  -webkit-backface-visibility: hidden;
  outline: 1px solid transparent;
  transform-origin: bottom center;
  will-change: transform; 
}

.grid-container:after {
  background-position: center bottom;
  background-size: 40px 40px;
  background-image: 
  linear-gradient(to right, blue 1px, transparent 0), 
  linear-gradient(to bottom, blue 3px, transparent 0);
}

<section class="grid-container">
</section>

Thanks in advance for your suggestions :D

解决方案

You can use mask-image with an alpha gradient to achieve the effect you're looking for.

.grid-container:after { 
   -webkit-mask-image: -webkit-gradient(linear, left 90%, left top, from(rgba(0,0,0,1)), to(rgba(0,0,0,0)));
   mask-image: gradient(linear, left 90%, left top, from(rgba(0,0,0,1)), to(rgba(0,0,0,0)));
}
