IS it possible, I know all the following shapes are possible in this link:

but cross must be possible too. When I say cross I mean like this:

但交叉也必须是可能的。当我说十字架时，我的意思是这样的：

You could achieve something like this with pseudoelements only:

你可以只用伪元素来实现这样的事情：

http://jsbin.com/upiyoc/1/edit

#cross {
   width: 100px;
   height: 100px;
   position: relative;
}

#cross:before, #cross:after {
  content: "";
  position: absolute;
  z-index: -1;
  background: #d00;
}

#cross:before {
  left: 50%;
  width: 30%;
  margin-left: -15%;
  height: 100%;
}

#cross:after {
  top: 50%;
  height: 30%;
  margin-top: -15%;
  width: 100%;
}

The size of the cross will proportionally scale, according to the widthand heightof the #crosselement

根据元素的width和height，十字的大小将按比例缩放#cross

Update: another solution (using less code) could simply involve multiple linear-gradients (without pseudolements) e.g.

更新：另一个解决方案（使用更少的代码）可以简单地涉及多个线性梯度（没有伪元素）例如

#cross {
  width: 100px;
  height: 100px;

  background: linear-gradient(to bottom, transparent 35%, 
                                         #d00 35%, 
                                         #d00 65%,  
                                         transparent 65%),

              linear-gradient(to right, transparent 35%, 
                                         #d00 35%, 
                                         #d00 65%,  
                                         transparent 65%),
}

Of course it is. You just have to use two elements : See http://jsfiddle.net/92XTx/2/

当然是这样。你只需要使用两个元素：见http://jsfiddle.net/92XTx/2/

The enclosing div is relatively positioned so that both children can be absolutely positioned.

封闭的 div 被relative定位，以便两个孩子都可以绝对定位。

#cross {
    position: relative;
    width: 150px;
    height: 150px;
}

Here they are both absolutely positioned:

在这里，它们都是绝对定位的：

#cross div {
    position: absolute;
    background: red;
}

to make them superpose.

使它们重叠。

And then create your shapes:

然后创建你的形状：

.cross-vertical {
    left: 33%;
    width: 33%;
    height: 100%;
}

.cross-horizontal {
    top: 33%;   
    width: 100%;
    height: 33%;
}

Because all the answers I see here look either lengthy or vendor-prefix-dependent,

因为我在这里看到的所有答案看起来都很冗长或依赖于供应商前缀，

#cross { 
  background: red; 
  height: 100px; 
  position: relative; 
  left: 50px;
  width: 20px; 
} 
#cross:after { 
  background: red; 
  content: ""; 
  height: 20px; 
  left: -40px; 
  position: absolute; 
  top: 40px; 
  width: 100px; 
}

<div id="cross"></div>

回答by Danield

This can be done with a regular '+' plus character together with a text-stroke

这可以通过常规的“+”加号字符和 text-stroke

DEMO(Webkit,Android only)

演示（Webkit，仅限Android）

div {
  font-size: 80px;
  -webkit-text-stroke: 20px red;
  display: inline-block;
  padding: 0 20px;
}

<div>+</div>

CSS Transform can be easily used to achieve plus shape

CSS Transform 可以轻松实现加号形状

.close {
  position: absolute;
  right: 10px;
  top: 6px;
  width: 20px;
  height: 20px;
  opacity: 0.3;
}
.cross:before, .cross:after {
  position: absolute;
  left: 15px;
  content: ' ';
  height: 21px;
  width: 2px;
  background-color: #333;
}
.cross:before {
  transform: rotate(0deg);
}
.cross:after {
  transform: rotate(-90deg);
}
