CSS中的加号 [英] Make plus symbol in CSS

问题描述

我有下面的CSS代码，该代码给出了 + 符号，但与设计基本不匹配，因此需要变薄.请参见摘要和 codpen

I have the below CSS code which gives the + symbol but not matches the design basically it needs to be thin. See snippet and codpen

.plus {
  position:relative;
  border: 1px dotted white;
  width: 3px;
  height: 3px;
  background-color: black;
  box-sizing: border-box;
  transform: scale(11);
}

<div class="plus"></div>

应类似于以下符号:

任何其他样式对我来说也都不错，但应该看起来像快照.

Any other styling is also fine for me but should look like the snapshot.

推荐答案

使用多个背景，如下所示:

Use muliple background like below:

.plus {
  display:inline-block;
  width:50px;
  height:50px;
  
  background:
    linear-gradient(#fff,#fff),
    linear-gradient(#fff,#fff),
    #000;
  background-position:center;
  background-size: 50% 2px,2px 50%; /*thickness = 2px, length = 50% (25px)*/
  background-repeat:no-repeat;
}

.alt {
  background:
    linear-gradient(#000,#000),
    linear-gradient(#000,#000);
  background-position:center;
  background-size: 50% 2px,2px 50%; /*thickness = 2px, length = 50% (25px)*/
  background-repeat:no-repeat;
}
.radius {
  border-radius:50%;
}

<div class="plus">
</div>

<div class="plus alt">
</div>

<div class="plus radius">
</div>

这是透明的:

.plus {
  width:50px;
  height:50px;
  display:inline-block;
  
  background:
    linear-gradient(#000,#000) top left,
    linear-gradient(#000,#000) top right,
    linear-gradient(#000,#000) bottom left,
    linear-gradient(#000,#000) bottom right;
  background-size: calc(50% - 1px) calc(50% - 1px); /*thickness = 2px (2*1px) */
  background-repeat:no-repeat;
  border:10px solid #000; /*length = 30px (50px - 2x10px) */
  box-sizing:border-box;
}

.radius {
  border-radius:50%;
}

body {
 background:pink;
}

<div class="plus">
</div>

<div class="plus radius">
</div>

我们可以添加CSS变量来轻松控制总体形状:

We can add CSS variable to easily control the overal shape:

.plus {
  --t:2px;   /* Thickness */
  --l:40px;  /* size of the symbol */
  --s:10px;  /* space around the symbol */
  --c1:#fff; /* Plus color*/
  --c2:#000; /* background color*/

  display:inline-block;
  width:var(--l);
  height:var(--l);
  padding:var(--s);
  box-sizing:border-box; /*Remove this if you don't want space to be included in the size*/
  
  background:
    linear-gradient(var(--c1),var(--c1)) content-box,
    linear-gradient(var(--c1),var(--c1)) content-box,
    var(--c2);
  background-position:center;
  background-size: 100% var(--t),var(--t) 100%;
  background-repeat:no-repeat;
}

.radius {
  border-radius:50%;
}

<div class="plus"></div>
<div class="plus" style="--l:35px;--t:3px;--c2:green"></div>
<div class="plus" style="--l:50px;--t:1px;--s:5px;--c1:red;"></div>
<div class="plus" style="--l:35px;--t:5px;--s:0px;--c1:blue;--c2:orange;"></div>

<br>
<div class="plus radius"></div>
<div class="plus radius" style="--l:35px;--t:3px;--c2:green"></div>
<div class="plus radius" style="--l:50px;--t:1px;--s:5px;--c1:red;"></div>
<div class="plus radius" style="--l:35px;--t:5px;--s:0px;--c1:blue;--c2:orange;"></div>
