创建可以使用html，css填充颜色的自定义图形

Question

此自定义图形需要填充三种不同的颜色。每种颜色都将填充1-100％。所以蓝色将从头到脚填充（1-100％），红色将从头部的底部到头顶（1-100％）填充，因此橙色。这可能使用svg / canvas或任何其他方式吗？

Answer 1

CSS动画方法

1. 使用不同的div分割三个不同的颜色部分。根据优先级将其放在HTML中，或者无论标记如何都给它z-index。
2. 对用于创建支架和填充背景的颜色部分进行细分。虽然可以使用:before和:after创建，但我使用了嵌套div。
3. 创建一个从0％高度过渡到100％高度的填充关键帧动画。有关填充动画的更多信息，请参阅以下答案：CSS Wipe up animation
4. 根据您拥有的形状数量，需要先计算animation-delay。如果第一个形状的动画持续时间为2秒，则给出下一个形状动画延迟2秒，这会产生连续效果。

操纵边界半径，位置，宽度和高度值以获得所需的形状和位置。
