我尝试构建一种进度条,类似于Chris Coyier在这里所做的:https://css-tricks.com/css3-progress-bars/,除了我想将SVG剪切路径应用于周围的div元素。
例如,我想将SVG剪切路径应用于.rating-stars
:
<div class="rating-stars">
<span class="rating"></span>
</div>
您可以在此处查看我目前所拥有的内容:http://codepen.io/rleichty/pen/GrWmRR
由于某些原因,它在Safari中不起作用,我也不确定如何调整SVG剪切路径的大小(如果可能的话)。
有谁知道如何实现这一目标,或者可能有更好的解决方案?

你可以通过调整这个SCSS变量来调整星星的高度$ratingHeight: 100px;
你不需要使用变量,但它只是调整一个值就更简单了(你也可以翻转它以便宽度优先)。
我在https://sarasoueidan.com/blog/css-svg-clipping/找到了很多帮助,因为她注意到了:
此处需要注意的一件重要事项是当您使用
objectBoundingBox
值时,为<clipPath>
<的内容指定的坐标strong>必须在[0,1] 范围内 - 坐标系变为单位系统,clipPath
内的形状坐标必须是该范围内的分数。
所以我不得不将SVG坐标调整为分数。
为了保持基于百分比的剪切路径的宽高比,我在How do I keep the aspect ratio of a percentage based clipping path?找到了帮助,只使用了padding-bottom
技巧。
现在您需要做的就是使用jQuery动态设置.rating
元素的宽度来表示星级。就我而言,我将从Goodreads中提取数据。
我个人喜欢这种方法,而不是每个评级都有单独的星形图像。它更简单,更轻巧,并且基于矢量和响应。
