Question

I have the following CSS:-

a.btn.white-grad {
    background: $lgrey;
    color: #313149 !important;
    border: 1px solid #000;
    border-image-source: linear-gradient(to right, #9c20aa, #fb3570);
    border-image-slice: 20;
    float: left;
    @include font-size(26);
    margin: 75px 0;
}

Adding border-radius: 5px doesn't seem to do anything, I figured it's because I'm using border gradient, is there a way for me to achieve the desired 5px border radius at all?

Answer 1

您不能将border-radius用于渐变。这是另一个您可以依赖多个背景并调整background-clip的想法：

.white-grad {
    background: 
     linear-gradient(#ccc,#ccc) padding-box, /*this is your grey background*/
     linear-gradient(to right, #9c20aa, #fb3570) border-box;
    color: #313149;
    padding:10px;
    border: 5px solid transparent;
    border-radius:15px;
    display:inline-block;
    margin: 75px 0;
}

<div class="white-grad"> Some text here</div>

如果要透明，可以考虑使用SVG，如下所示：

svg {
  width:200px;
  height:100px;
  margin:10px;
}

<svg xmlns="http://www.w3.org/2000/svg">
<defs>
      <linearGradient id="Gradient" x1="0" x2="100" y1="0" y2="0" gradientUnits="userSpaceOnUse">
         <stop stop-color="#9c20aa" offset="0"/>
         <stop stop-color="#fb3570" offset="1"/>
      </linearGradient>
   </defs>
  <rect x="5" y="5" height="100%" width="100%" style="width:calc(100% - 10px);height:calc(100% - 10px)" rx="20" ry="20" stroke-width="10" fill="transparent" stroke="url(#Gradient)"/>
</svg>

您可以申请作为背景：

.white-grad {
    background:url('data:image/svg+xml;utf8,<svg   xmlns="http://www.w3.org/2000/svg" ><defs><linearGradient id="Gradient" x1="0" x2="100" y1="0" y2="0" gradientUnits="userSpaceOnUse"><stop stop-color="%239c20aa" offset="0"/><stop stop-color="%23fb3570" offset="1"/></linearGradient></defs><rect x="5" y="5" width="100%" height="100%" style="height:calc(100% - 10px);width:calc(100% - 10px)" rx="20" ry="20" stroke-width="10" fill="transparent" stroke="url(%23Gradient)"/></svg>');
    color: #313149;
    padding:25px;
    border-radius:15px;
    display:inline-block;
    margin: 75px 0;
}

body {
  background:yellow;
}

<div class="white-grad"> Some text here</div>

<div class="white-grad"> text very loooooooooooong here</div>

由于calc()的支持，以上内容似乎只能在Chrome上正常运行。我们可以稍微调整代码以使其在Firefox上运行：

svg {
  width:200px;
  height:100px;
  margin:10px;
  overflow:visible;
}

<svg xmlns="http://www.w3.org/2000/svg">
<defs>
      <linearGradient id="Gradient" x1="0" x2="100" y1="0" y2="0" gradientUnits="userSpaceOnUse">
         <stop stop-color="#9c20aa" offset="0"/>
         <stop stop-color="#fb3570" offset="1"/>
      </linearGradient>
   </defs>
  <rect x="5" y="5" height="100%" width="100%"  rx="20" ry="20" stroke-width="10" fill="transparent" stroke="url(#Gradient)"/>
</svg>

和背景版本：

.white-grad {
    background:url('data:image/svg+xml;utf8,<svg   xmlns="http://www.w3.org/2000/svg" ><defs><linearGradient id="Gradient" x1="0" x2="100" y1="0" y2="0" gradientUnits="userSpaceOnUse"><stop stop-color="%239c20aa" offset="0"/><stop stop-color="%23fb3570" offset="1"/></linearGradient></defs><rect x="5" y="5" width="100%" height="100%" rx="20" ry="20" transform="scale(0.93,0.88)" stroke-width="10" fill="transparent" stroke="url(%23Gradient)"/></svg>');
    color: #313149;
    padding:25px;
    border-radius:15px;
    display:inline-block;
    margin: 75px 0;
}

body {
  background:yellow;
}

<div class="white-grad"> Some text here</div>

<div class="white-grad"> text very loooooooooooong here</div>

Answer 2

您需要将按钮包装在div中，然后在该父div上设置$(".table tr td:nth-child(3)").each(function(){。为了工作，您还必须将border-radius设置为该父div。像这样：

overflow:hidden

.btn-wrap {
    border-radius: 5px;
    overflow: hidden;
    margin: 20px;
    width: 60px;
}
a.btn.white-grad {
    background: #eee;
    color: #313149 !important;
    border: 20px solid #000;
    border-image-source: linear-gradient(to right, #9c20aa, #fb3570);
    border-image-slice: 20;
    line-height: 2;
}
