填充一半的svg多边形形状 - 星形

时间：2018-02-07 20:51:35

标签： css css3 svg polygon

我正在使用它，并希望在星级选定的类中添加一个新的css类'half'，只用背景颜色填充一半的星形：＃e54800

https://foundation.zurb.com/building-blocks/blocks/star-rating.html

所以它会是：<xsl:template match="Box[@ury != preceding-sibling::Box/@ury]/Text"> <xsl:copy><xsl:apply-templates/></xsl:copy> </xsl:template> 

<div class="star selected half">

CSS：

<div class="rating-block">
    <div class="rating-block-rating" data-rating>
        <div class="star selected">

您可以使用另一个svg定义渐变（以避免在每个svg中重复它）并使用带有fill的渐变。如果您想要不同的其他fill

，则可以轻松调整％值或创建更多渐变 

.rating-block {
  padding: 2px 5px;
  display: flex;
  align-items: center;
  justify-content: space-between;
}

.rating-block .ratings-type {
  margin-right: 1rem;
  margin-bottom: 0;
}

.rating-block .rating-block {
  display: flex;
  align-items: center;
  margin-bottom: 2rem;
}

.rating-block .rating-block-rating {
  display: flex;
}

.rating-block .star {
  cursor: pointer;
  stroke: #cc4b37;
}

.rating-block .rating-block-rating .star.selected polygon {
  fill: #cc4b37;
}
.rating-block .rating-block-rating .star.half polygon {
  fill: url(#grad);
}

.rating-block .rating-block-rating.is-voted .star polygon {
  fill: #cc4b37;
}

.rating-block .rating-block-rating.is-voted .star.selected~.star polygon {
  fill: transparent;
}
<svg height="0" width="0">
  <defs>
    <linearGradient id="grad" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:#cc4b37;stop-opacity:1" />
      <stop offset="50%" style="stop-color:#cc4b37;stop-opacity:1" />
      <stop offset="50%" style="stop-color:transparent;stop-opacity:1" />
      <stop offset="100%" style="stop-color:transparent;stop-opacity:1" />

顺便说一下，这是一种处理评级的简单方法，无需多次使用svg并为填充定义渐变。您可以使用svg作为背景并简单地控制宽度来控制评级：

.rating{
  width: calc(45px * 5);
  height: 45px;
  background: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" width="45" height="45" viewBox="-40 -40 80 80"><path fill="%23cc4b37" stroke="%23cc4b37" stroke-width="2"  d="M 0.000 20.000 L 23.511 32.361 L 19.021 6.180 L 38.042 -12.361 L 11.756 -16.180 L 0.000 -40.000 L -11.756 -16.180 L -38.042 -12.361 L -19.021 6.180 L -23.511 32.361 L 0.000 20.000 "/></svg>');
  position:relative;
}
.rating:before {
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  width: calc(45px * 5);
  z-index:-1;
  background: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" width="45" height="45" viewBox="-40 -40 80 80"><path fill="transparent" stroke="%23cc4b37" stroke-width="2"  d="M 0.000 20.000 L 23.511 32.361 L 19.021 6.180 L 38.042 -12.361 L 11.756 -16.180 L 0.000 -40.000 L -11.756 -16.180 L -38.042 -12.361 L -19.021 6.180 L -23.511 32.361 L 0.000 20.000 "/></svg>');
}
<div class="rating">
</div>
<div class="rating" style="width:calc(45px * 2)">
</div>
<div class="rating" style="width:calc(45px * 2.5)">
</div>
<div class="rating" style="width:calc(45px * 4.75)">
</div>
<div class="rating" style="width:calc(45px * 1.75)">
</div>

还可以使用CSS变量进行改进：

.rating{
  width: calc(45px * 5);
  height: 45px;
  background: 
    url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" width="45" height="45" viewBox="-40 -40 80 80"><path fill="transparent" stroke="%23cc4b37" stroke-width="2"  d="M 0.000 20.000 L 23.511 32.361 L 19.021 6.180 L 38.042 -12.361 L 11.756 -16.180 L 0.000 -40.000 L -11.756 -16.180 L -38.042 -12.361 L -19.021 6.180 L -23.511 32.361 L 0.000 20.000 "/></svg>');
  position:relative;
}
.rating:before {
  content:"";
  position:absolute;
  top:0;
  bottom:0;
  left:0;
  width: calc(45px * var(--r,1));
  background: url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" width="45" height="45" viewBox="-40 -40 80 80"><path fill="%23cc4b37" stroke="%23cc4b37" stroke-width="2"  d="M 0.000 20.000 L 23.511 32.361 L 19.021 6.180 L 38.042 -12.361 L 11.756 -16.180 L 0.000 -40.000 L -11.756 -16.180 L -38.042 -12.361 L -19.021 6.180 L -23.511 32.361 L 0.000 20.000 "/></svg>');
}
<div class="rating">
</div>
<div class="rating" style="--r:2">
</div>
<div class="rating" style="--r:2.5">
</div>
<div class="rating" style="--r:4.75">
</div>
<div class="rating" style="--r:1.75">
</div>
