如何在 CSS 中创建响应式棋盘背景？

Question

我想要一个响应式棋盘格背景，看起来应该像颜色选择器中的背景：

我尝试了什么：

.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：

我的结果没有反应。（我有固定的像素大小）
如果我有更大的背景或更小的元素，我将需要大量代码。
我没有实现居中模式或使用 background-repeat: round

如果可能的话，我不希望棋盘格背景中有任何被切断的元素。

不是这样的（从右边和底部剪掉）：

这里有一个思路依赖conic-gradient:

.chess {
  background:
    repeating-conic-gradient(
        #fff 0deg  90deg,
        grey 0 180deg) 
    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>

如果你想有相同的尺寸并且没有截断，你也可以考虑round of background-repeat:

.chess {
  background:
    repeating-conic-gradient(
        #fff 0deg 90deg,
        grey 0deg 180deg) 
    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>

为了更好的支持，您可以用 SVG 替换渐变以获得相同的结果：

.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>

并且具有固定尺寸：

.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>

Answer 2

使用这个：

.chess {
  background-image:
    linear-gradient(45deg, #ccc 25%, transparent 25%),
    linear-gradient(-45deg, #ccc 25%, transparent 25%),
    linear-gradient(45deg, transparent 75%, #ccc 75%),
    linear-gradient(-45deg, transparent 75%, #ccc 75%);
  background-size: 60px 60px;
  background-position: 0 0, 0 29px, 29px -29px, -29px 0px;
}
.btn {}

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


.fas.f5em {
  font-size: 5em;
}

.fas.f35em {
  font-size: 35em;
}

<div>
  <div class="btn btn-outline-secondary chess">
  <i class="fas fa-car f5em"></i>
  </div>
<div>

<div>
  <div class="btn btn-outline-secondary chess">
  <i class="fas fa-car f35em"></i>
