css - 这是设置具有两个色标的 CSS 渐变的正确方法吗？

Question

一段时间以来，我一直在尝试让我的代码适用于以下所有浏览器前缀。这就是我想出的。有人可以告诉我这是否是使用 Less 对渐变进行编码的正确方法？特别是我对 -webkit-linear-gradient 感到困惑，因为我找不到如何使用规范来做到这一点。

我的 less 代码:

.setTopGradient(@startClr, @endClr, @st1Clr, @st1Pos, @st2Clr, @st2Pos) {
   @st1PosPercent: @st1Pos * 100%;
   @st2PosPercent: @st2Pos * 100%;

   background: -moz-linear-gradient(
        top,
        @startClr,
        @st1Clr @st1PosPercent,
        @st2Clr @st2PosPercent,
        @endClr
   );

   background: -webkit-gradient(
        linear, 
        left @startClr,
        left @endClr, 
        color-stop(@st1Pos, @st1Clr),
        color-stop(@st2Pos, @st2Clr)
   );

   background: -webkit-linear-gradient(
      linear,
      left top,
      left bottom,
      from(@startClr),
      to(@endClr),
      color-stop(@st1Pos, @st1Clr),
      color-stop(@st2Pos, @st2Clr)
   );

    background: -ms-linear-gradient(
        @startClr 0%,
        @st1Clr @st1PosPercent,
        @st2Clr @st2PosPercent,
        @endClr 100%
    );

    background: -o-linear-gradient(
        @startClr 0%,
        @st1Clr @st1PosPercent,
        @st2Clr @st2PosPercent,
        @endClr 100%
    );

    background: linear-gradient(
        to @endClr,
        @st1Clr @st1PosPercent,
        @st2Clr @st2PosPercent,
        @endClr 100%
    );

}

示例输入:

.setTopGradient(#8b8b8b,#bfbfbf,#a9a9a9,0.1,#bdbdbd,0.3);

输出 CSS:

  background: -moz-linear-gradient(top, #8b8b8b, #a9a9a9 10%, #bdbdbd 30%, #bfbfbf);
  background: -webkit-gradient(linear, left #8b8b8b, left #bfbfbf, color-stop(0.1, #a9a9a9), color-stop(0.3, #bdbdbd));
  background: -webkit-linear-gradient(linear, left top, left bottom, from(#8b8b8b), to(#bfbfbf), color-stop(0.1, #a9a9a9), color-stop(0.3, #bdbdbd));
  background: -ms-linear-gradient(#8b8b8b 0%, #a9a9a9 10%, #bdbdbd 30%, #bfbfbf 100%);
  background: -o-linear-gradient(#8b8b8b 0%, #a9a9a9 10%, #bdbdbd 30%, #bfbfbf 100%);
  background: linear-gradient(to #bfbfbf, #a9a9a9 10%, #bdbdbd 30%, #bfbfbf 100%);

在回答这个问题时，让你的止损只是百分比(没有小数)，这样这些线......

  background: -webkit-gradient(linear, left #8b8b8b, left #bfbfbf, color-stop(0.1, #a9a9a9), color-stop(0.3, #bdbdbd));
  background: -webkit-linear-gradient(linear, left top, left bottom, from(#8b8b8b), to(#bfbfbf), color-stop(0.1, #a9a9a9), color-stop(0.3, #bdbdbd))

...成为...

  background: -webkit-gradient(linear, left #8b8b8b, left #bfbfbf, color-stop(10%, #a9a9a9), color-stop(30%, #bdbdbd));
  background: -webkit-linear-gradient(linear, left top, left bottom, from(#8b8b8b), to(#bfbfbf), color-stop(10%, #a9a9a9), color-stop(30%, #bdbdbd))
