css - 计算 IE11 中的百分比

Question

有没有办法让 css calc 函数在 IE11 中使用如下所示的偏移量？

这在 IE11 中不起作用:

div:nth-child(1) {
  background: hsl(114.54545, 44%, calc(55.88235% * 1.1));
}

静态百分比可以:

div:nth-child(2) {
  background: hsl(114.54545, 44%, 55.88235%);
}

Answer 1

您可以尝试使用额外的白色层来近似它以增加亮度，而不需要 calc()

div:nth-child(1) {
  background: hsl(114.54545, 44%, calc(55.88235% * 1.1));
}

div:nth-child(2) {
  background: hsl(114.54545, 44%, 55.88235%);
  position:relative;
  z-index:0;
}
div:nth-child(2):before {
 content:"";
 position:absolute;
 z-index:-1;
 top:0;
 left:0;
 right:0;
 bottom:0;
 background:rgba(255,255,255,0.1); 
}

<div>calc</div>
<div>static</div>

您还可以使用多个背景来实现:

div:nth-child(1) {
  background: hsl(114.54545, 44%, calc(55.88235% * 1.1));
}

div:nth-child(2) {
  background: 
    linear-gradient(rgba(255,255,255,0.1),rgba(255,255,255,0.1)),
    hsl(114.54545, 44%, 55.88235%); 
}

<div>calc</div>
<div>static</div>
