如何在背景速记规则上使用线性渐变

Question

为什么我会得到不同的结果：

body {
  background: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black), 
  linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black) 0 0, 30px 30px/60px 60px  #eee;
}

在尝试获得结果时，我得到了这个：

body {
  width: 100px;
  height: 100px;
  background-color: #eee;
  background-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black), 
  linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black);
  background-size: 60px 60px;
  background-position:0 0, 30px 30px;
}

？

代码笔

Answer 1

它的简写是：

body {
  background: 
    0 0/60px 60px linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black), 
    30px 30px/60px 60px linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black) #eee;
}

您需要设置每个背景图像的位置和大小

Answer 2

你只是在这里得到了稍微错误的语法：

background: linear-gradient(45deg, black 25%, transparent 25%,
              transparent 75%, black 75%, black),
            linear-gradient(45deg, black 25%, transparent 25%,
              transparent 75%, black 75%, black) 0 0, 30px 30px/60px 60px  #eee;
                                                   ^^^

这里的逗号是错误的 - 它需要结束

              transparent 75%, black 75%, black) 0 0 30px 30px/60px 60px  #eee;
