CSS 通过伪元素创建图标

  • 772

告诉我如何创建某个类，并将其分配给这个类，<div>您可以获得与此类似的图像。

图标

我有原版空白。

body{
  margin: 0;
  background-color: #090C09;
}


.gr {
  width: 60px;
  height: 60px;
  
  
  position: relative;
  box-sizing: border-box;
  border: 2px solid #000;
  outline: 1px solid rgba(30, 32, 29, 0.4);
  outline-offset: 3px;
  background-image: linear-gradient(#0e130f 2px, transparent 2px),
  linear-gradient(90deg, #0e130f 2px, transparent 2px);
  background-size: 2px 2px;
  background-color: #0B100A;


  box-shadow: inset 0 0 40px 0 rgba(0, 0, 0, 0.9);
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}
<div class="gr"></div>

但我不明白如何用CSS来实现这个“十字”。也许有人可以展示？最好是通过:before :after

/// 添加了一个 SVG 示例

body{
  margin: 0;
  background-color: #090C09;
}


.gr {
width: 60px;
height: 60px;
position: relative;
box-sizing: border-box;
border: 2px solid #000;
outline: 1px solid rgba(30, 32, 29, 0.4);
outline-offset: 3px;
background-image: 
  linear-gradient(#0e130f 2px, transparent 2px),
  linear-gradient(90deg, #0e130f 2px, transparent 2px);
background-size: 60px 60px;
background-color: #0B100A;
box-shadow: inset 0 0 40px 0 rgba(0, 0, 0, 0.9);

    这就是原始图像的样子（放大 5 倍并增亮 150%）：

    在此输入图像描述

    基于此，得出以下结论：

    .gr {
  /* Масштаб --> */ font-size: 16px;
  position: relative;
  width: 23.25em; height: 23.25em;
  background-color: #272f24;
  box-shadow: inset 0 0 0.1875em 1.3125em #1a1f19, inset 0 0 0.875em 1.875em #000, inset 0 0 7.5em 5.625em #0b1009;
  /* Раскомментировать и настроить filter: brightness(.3); */
}
.gr::before {
  content: '';
  position: absolute;
  inset: 0;
  background: center / 21.875em 21.875em linear-gradient(45deg, #0000 calc(50% - 0.75em), #262d24 calc(50% - 0.375em) calc(50% + 0.375em), #0000 calc(50% + 0.75em)) no-repeat, center / 21.875em 21.875em linear-gradient(-45deg, #0000 calc(50% - 0.75em), #262d24 calc(50% - 0.375em) calc(50% + 0.375em), #0000 calc(50% + 0.75em)) no-repeat, center / 20.5em 20.5em linear-gradient(45deg, #0000 calc(50% - 1.5em), #0008 calc(50% - 0.875em) calc(50% + 0.875em), #0000 calc(50% + 1.5em)) no-repeat, center / 20.5em 20.5em linear-gradient(-45deg, #0000 calc(50% - 1.5em), #0008 calc(50% - 0.875em) calc(50% + 0.875em), #0000 calc(50% + 1.5em)) no-repeat;
  --mask: center / 22.5em 22.5em radial-gradient(circle, #000f 14.375em, #0000 15.3125em) no-repeat;
  -webkit-mask: var(--mask); mask: var(--mask);
  /* Дополнительное размытие filter: blur(0.125em); */
}

body { background-color: #090C09; }
    <div class="gr"></div>

  2. 十字由两条旋转线组成。

    要旋转，您可以使用该功能rotate

    线条本身可以制成常规元素或伪元素：只需指定宽度和高度。

    接下来，只需确定元素的背景即可。

    对于中心的正确位置，值得添加position:absolute

    最后它可能看起来像这样：

    body {
  margin: 0;
  background-color: #090C09;
}

.gr {
  width: 60px;
  height: 60px;
  position: relative;
  box-sizing: border-box;
  border: 2px solid #000;
  outline: 1px solid rgba(30, 32, 29, 0.4);
  outline-offset: 3px;
  background-image: linear-gradient(#0e130f 2px, transparent 2px), linear-gradient(90deg, #0e130f 2px, transparent 2px);
  background-size: 2px 2px;
  background-color: #0B100A;
  box-shadow: inset 0 0 40px 0 rgba(0, 0, 0, 0.9);
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
}

.gr::before,
.gr::after {
  content: '';
  background: red;
  height: 1px;
  width: 100%;
  position: absolute;
}

.gr::before {
  transform: rotate(-45deg);
}

.gr::after {
  transform: rotate(45deg);
}


}
    <div class="gr"></div>
