创建可以使用 html、css 填充颜色的自定义图形

Question

这个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%。所以蓝色将从腿部填充到头部（1-100%），红色将从头部底部填充到头顶（1-100%），所以橙色。这可以使用 svg / canvas 或任何其他方式吗？

Answer 1

CSS动画方法

1. 用不同的 div 分割三个不同颜色的部分。根据优先级将其放置在 HTML 中，或者将其设置为 z-index，而不管标记如何。
2. 细分用于创建支架和填充背景的颜色部分。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可以在这些答案中找到：CSS Wipe up animation
4. animation-delay 之前需要根据你拥有的形状数量来计算。如果第一个形状的动画持续时间为 2 秒，则将下一个形状的动画延迟设置为 2 秒，以创建顺序效果。

操作边框半径、位置、宽度和高度值以获得所需的形状和位置。
