填充一半的svg多边形形状-星形 [英] fill half of svg polygon shape - star
问题描述
我正在使用此函数,并希望将新的css类"half"添加到选定的星形类中,以仅用背景颜色填充星形的一半:#e54800
I am using this and was looking to add a new css class 'half' to the star selected class, to only fill half the star shape with the background color: #e54800
https://foundation.zurb.com/building-blocks /blocks/star-rating.html
因此它将是:<div class="star selected half">
<div class="rating-block">
<div class="rating-block-rating" data-rating>
<div class="star selected">

推荐答案
您可以使用另一个svg定义渐变(以避免在每个svg中重复该渐变),并将渐变与fill
结合使用.如果需要其他fill
You can define a gradient using another svg (to avoid repeating it inside each one) and use the gradient with fill
. You can easily adjust the % values or create more gradient if you want different other fill

padding: 2px 5px;

通过这种方式,可以轻松处理等级,而无需多次使用svg并为填充定义渐变.您可以使用svg作为背景,只需控制宽度即可控制评分:
By the way here is an easier way to handle the rating without having to use the svg multiple time and define a gradient for the fill. You can use svg as background and simply control the width to control the rating:
.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>
也可以通过CSS变量进行改进:
Can also be improved with CSS variable:
.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>
