如何在CSS中创建响应式棋盘背景? [英] How to create a responsive checkerboard background in CSS?

问题描述

我希望有一个固定的棋盘格背景，看起来应该像颜色选择器中的背景:

I want to have a resposive checkerboard background that should look like the background in a color selector:

我尝试过的事情:

.chess {
  background-image: 
    linear-gradient(90deg, #999 30px, white 30px), 
    linear-gradient(90deg, white 30px, #999 30px), 
    linear-gradient(90deg, #999 30px, white 30px), 
    linear-gradient(90deg, white 30px, #999 30px), 
    linear-gradient(90deg, #999 30px, white 30px), 
    linear-gradient(90deg, white 30px, #999 30px), 
    linear-gradient(90deg, #999 30px, white 30px);
  background-position: 0 0, 0 30px, 0 60px, 0 90px, 0 120px;
  background-repeat: repeat-x;
  background-size: 60px 30px;
  height: 150px;
  margin: 15px auto;
  width: 30%;
}


.fas {
  text-align: center;
  font-size: 10em
}

<div>
  <div class="btn btn-outline-secondary chess">
  <i class="fas fa-car"></i>
  </div>
<div>

问题:

• 我的结果不是固定的. (我的像素大小固定)
• 如果我有较大的背景或较小的元素，则需要很多代码.
• 我没有达到使模式居中或使用 background-repeat: round

如果可能的话，我不希望棋盘背景中的任何内容都被剪掉.

If it is possible I don't want any cut off elements in the checkerboard background.

不是这样的(在右侧和底部切断):

Not like this (cut off on the right and bottom):

推荐答案

这是一个依赖圆锥体渐变，但实际上仅在Chrome上受支持:

Here is an idea that rely on conic-gradient but supported only on Chrome actually:

.chess {
  background:
    conic-gradient(#fff 0deg ,#fff 90deg,
                   grey 90deg,grey 180deg,
                   #fff 180deg,#fff 270deg,
                   grey 270deg,grey 360deg) 
    0 0/25% 25%;
  margin: 15px;
  padding:10px;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css" rel="stylesheet"/>

<div class="chess fas fa-7x fa-car"></div>
<div class="chess fas fa-5x fa-car"></div>
<div class="chess fas fa-10x fa-user"></div>
<div class="chess fas fa-3x fa-phone"></div>

如果您希望具有相同的尺寸并且没有截断，也可以考虑使用background-repeat中的round:

You can also consider round of background-repeat if you want to have the same size and no cut off:

.chess {
  background:
    conic-gradient(#fff 0deg ,#fff 90deg,
                   grey 90deg,grey 180deg,
                   #fff 180deg,#fff 270deg,
                   grey 270deg,grey 360deg) 
    0 0/40px 40px round;
  margin: 15px;
  padding:10px;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css" rel="stylesheet"/>

<div class="chess fas fa-7x fa-car"></div>
<div class="chess fas fa-5x fa-car"></div>
<div class="chess fas fa-10x fa-user"></div>
<div class="chess fas fa-3x fa-phone"></div>

为了获得更好的支持，您可以使用SVG替换渐变以得到相同的结果:

For better support, you can replace the gradient with an SVG to have the same result:

.chess {
  background:
    url('data:image/svg+xml;utf8,<svg preserveAspectRatio="none"  viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg"><rect x="0" y="0" width="5" height="5" fill="grey" /><rect x="5" y="5" width="5" height="5" fill="grey" /><rect x="5" y="0" width="5" height="5" fill="white" /><rect x="0" y="5" width="5" height="5" fill="white" /></svg>') 
    0 0/25% 25%;
  margin: 15px;
  padding:10px;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css" rel="stylesheet"/>

<div class="chess fas fa-7x fa-car"></div>
<div class="chess fas fa-5x fa-car"></div>
<div class="chess fas fa-10x fa-user"></div>
<div class="chess fas fa-3x fa-phone"></div>

并且具有固定大小:

.chess {
  background:
    url('data:image/svg+xml;utf8,<svg preserveAspectRatio="none"  viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg"><rect x="0" y="0" width="5" height="5" fill="grey" /><rect x="5" y="5" width="5" height="5" fill="grey" /><rect x="5" y="0" width="5" height="5" fill="white" /><rect x="0" y="5" width="5" height="5" fill="white" /></svg>') 
    0 0/40px 40px round;
  margin: 15px;
  padding:10px;
}

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.7.2/css/all.min.css" rel="stylesheet"/>

<div class="chess fas fa-7x fa-car"></div>
<div class="chess fas fa-5x fa-car"></div>
<div class="chess fas fa-10x fa-user"></div>
<div class="chess fas fa-3x fa-phone"></div>
