渐变 CSS 箭头

Question

pos如何将 CSS 箭头设为渐变而不是 os 纯色？

这是我的 CSS"

.breadcrumbDivider .arrow-right {
  width: 0; 
  height: 0; 
  border-top: 25px solid transparent;
  border-bottom: 25px solid transparent;
  border-left: 25px solid gold; 
  position: relative;
  margin-left: 360px;
}

我尝试使用 CSS 渐变背景图像渐变，但它需要边框参数，但不确定如何克服这个问题？

这是我尝试使用的渐变...

  background-color: #c9bc9e;
  background-image: -webkit-gradient(linear, left top, left bottom, from(#c9bc9e), to(#a89464));
  background-image: -webkit-linear-gradient(top, #c9bc9e, #a89464);
  background-image: -moz-linear-gradient(top, #c9bc9e, #a89464);
  background-image: -ms-linear-gradient(top, #c9bc9e, #a89464);
  background-image: -o-linear-gradient(top, #c9bc9e, #a89464);
  background-image: linear-gradient(top, #c9bc9e,#a89464);
  filter: progid:DXImageTransform.Microsoft.gradient(startColorStr='#c9bc9e', endColorStr='#a89464');

Answer 1

我用 'cutting out' 正方形 div 的箭头而不是 'generating' 箭头来做这个。它甚至还有悬停效果：

.arrow {
  height: 200px;
  width: 300px;
  background: rgb(169, 3, 41);
  background: -moz-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(169, 3, 41, 1)), color-stop(44%, rgba(143, 2, 34, 1)), color-stop(100%, rgba(109, 0, 25, 1)));
  background: -webkit-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -o-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -ms-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: linear-gradient(to bottom, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#a90329', endColorstr='#6d0019', GradientType=0);
  position: relative;
  overflow: hidden;
  transition: all 0.8s;
}
.arrow:before {
  content: "";
  position: absolute;
  top: 0;
  width: 70%;
  height: calc(100% - 80px);
  border-top: 40px solid white;
  border-bottom: 40px solid white;
  z-index: 10;
}
.arrow:after {
  content: "";
  position: absolute;
  right: 0;
  border-top: 100px solid white;
  border-bottom: 100px solid white;
  border-left: 100px solid transparent;
  z-index: 10;
}
.perc {
  position: absolute;
  top: 0;
  width: 0%;
  height: 100%;
  background: rgb(30, 87, 153);
  background: -moz-linear-gradient(top, rgba(30, 87, 153, 1) 0%, rgba(41, 137, 216, 1) 50%, rgba(32, 124, 202, 1) 51%, rgba(125, 185, 232, 1) 100%);
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(30, 87, 153, 1)), color-stop(50%, rgba(41, 137, 216, 1)), color-stop(51%, rgba(32, 124, 202, 1)), color-stop(100%, rgba(125, 185, 232, 1)));
  background: -webkit-linear-gradient(top, rgba(30, 87, 153, 1) 0%, rgba(41, 137, 216, 1) 50%, rgba(32, 124, 202, 1) 51%, rgba(125, 185, 232, 1) 100%);
  background: -o-linear-gradient(top, rgba(30, 87, 153, 1) 0%, rgba(41, 137, 216, 1) 50%, rgba(32, 124, 202, 1) 51%, rgba(125, 185, 232, 1) 100%);
  background: -ms-linear-gradient(top, rgba(30, 87, 153, 1) 0%, rgba(41, 137, 216, 1) 50%, rgba(32, 124, 202, 1) 51%, rgba(125, 185, 232, 1) 100%);
  background: linear-gradient(to bottom, rgba(30, 87, 153, 1) 0%, rgba(41, 137, 216, 1) 50%, rgba(32, 124, 202, 1) 51%, rgba(125, 185, 232, 1) 100%);
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#1e5799', endColorstr='#7db9e8', GradientType=0);
  z-index: 5;
  transition: all 0.8s;
}
.arrow:hover .perc {
  width: 100%;
}

<div class="arrow">
  <div class="perc"></div>
</div>

备注

原本是为进度条设计的，但如果需要可以去掉悬停效果。
仅适用于色块背景

所以，如果我剪下 'fancy stuff' 并向您展示它是如何工作的：

将鼠标悬停在下方以查看魔术：

.arrow {
  height: 200px;
  width: 300px;
  background: rgb(169, 3, 41);
  background: -moz-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -webkit-gradient(linear, left top, left bottom, color-stop(0%, rgba(169, 3, 41, 1)), color-stop(44%, rgba(143, 2, 34, 1)), color-stop(100%, rgba(109, 0, 25, 1)));
  background: -webkit-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -o-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: -ms-linear-gradient(top, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  background: linear-gradient(to bottom, rgba(169, 3, 41, 1) 0%, rgba(143, 2, 34, 1) 44%, rgba(109, 0, 25, 1) 100%);
  filter: progid: DXImageTransform.Microsoft.gradient(startColorstr='#a90329', endColorstr='#6d0019', GradientType=0);
  position: relative;
  overflow: hidden;
  transition: all 0.8s;
}
.arrow:before {
  content: "";
  position: absolute;
  top: 0;
  width: 100%;
  height: calc(100% - 80px);
  border-top: 40px solid white;
  border-bottom: 40px solid white;
  z-index: 10;
}
.arrow:after {
  content: "";
  position: absolute;
  right: 0px;
  border-top: 100px solid white;
  border-bottom: 100px solid white;
  border-left: 100px solid transparent;
  z-index: 10;
}
.arrow:hover:before {
  border-top: 40px solid tomato;
  border-bottom: 40px solid tomato;
}
.arrow:hover:after {
  border-top: 100px solid yellow;
  border-bottom: 100px solid blue;
}
