线性渐变边界修改

Question

您好，我这里的每个人都想更改，我们需要将删除线更新为相同的对角线-居中45度。请在下面找到代码...

.Product__widths__button {
    background: #FFFFFF;
    border: 1px solid #333333;
    color: #333333;
    display: block;
    font-size: 16px;
    line-height: 42px;
    height: 42px;
    text-align: center;
    padding-left: 20px;
    padding-right: 20px;
}
.Product__widths__button.disabled {
    color: #D1D1D1;
    background: linear-gradient(to top left, #fff 38px, #D1D1D1, #fff 40px);
    border-color: #D1D1D1;
}

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)</a>

这里要显示如下图

如果我还有其他需要，请让我。谢谢!!!

如果高度是固定的，则可以将背景尺寸设置为尺寸等于高度的正方形（在您的情况下为42px），并使其居中，如下所示：

.Product__widths__button {
  background: #FFFFFF;
  border: 1px solid #333333;
  color: #333333;
  display: block;
  font-size: 16px;
  line-height: 42px;
  height: 42px;
  text-align: center;
  padding-left: 20px;
  padding-right: 20px;
}

.Product__widths__button.disabled {
  color: #D1D1D1;
  background: 
    linear-gradient(to top left, 
      /*the center is 42px*cos(45deg) = 29.7px, we remove/add pixel around*/
      transparent 28px,#D1D1D1,transparent 31px) 
      center/42px 100% /*background-position/background-size  (100% is your height)*/
      no-repeat;
  border-color: #D1D1D1;
}

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)</a>

另一种想法是在您不知道确切高度的情况下将渐变做成一个大正方形，并且可以在动态高度下使用。

.Product__widths__button {
  background: #FFFFFF;
  border: 1px solid #333333;
  color: #333333;
  display: block;
  font-size: 16px;
  line-height: 42px;
  text-align: center;
  padding-left: 20px;
  padding-right: 20px;
}

.Product__widths__button.disabled {
  color: #D1D1D1;
  background: 
    linear-gradient(to top left, 
      /* the center is 500px*cos(45deg) = 353.5px*/
      transparent 351px,#D1D1D1,transparent 355px) 
      center/500px 500px /*background-position/background-size */
      no-repeat;
  border-color: #D1D1D1;
}

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)</a>

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)<br>another line</a>

没有background-size和background-position的另一种方法是简单地将度数设置为-45deg，您需要使用calc()和50%组合来找到中心

.Product__widths__button {
  background: #FFFFFF;
  border: 1px solid #333333;
  color: #333333;
  display: block;
  font-size: 16px;
  line-height: 42px;
  text-align: center;
  padding-left: 20px;
  padding-right: 20px;
}

.Product__widths__button.disabled {
  color: #D1D1D1;
  background: 
    linear-gradient(-45deg,transparent calc(50% - 2px),#D1D1D1,transparent calc(50% + 2px));
  border-color: #D1D1D1;
}

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)</a>

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)<br>another line</a>

您也可以使用倾斜元素作为背景进行尝试，以防万一您无法使用calc()

.Product__widths__button {
  background: #FFFFFF;
  border: 1px solid #333333;
  color: #333333;
  display: block;
  font-size: 16px;
  line-height: 42px;
  text-align: center;
  padding-left: 20px;
  padding-right: 20px;
  position:relative;
  z-index:0;
}

.Product__widths__button.disabled {
  color: #D1D1D1;
  border-color: #D1D1D1;
}
.Product__widths__button.disabled::before {
  content:"";
  position:absolute;
  z-index:-1;
  left:0;
  top:0;
  bottom:0;
  width:calc(50% - 2px); /*we remove half the border-width to have a perfect centring*/
  border-right:4px solid #D1D1D1;
  transform:skewX(-45deg);
}

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)</a>

<a id="width_1_1" class="Product__widths__button disabled"><span>W</span> (Wide)<br>another line</a>
