text-decoration-color

该text-decoration-color CSS属性设置由text-decoration-line属性所指定的线条的颜色。该颜色会应用于所有指定的线条。当一次设置多个线条装饰属性时，使用text-decoration简写属性可能会更方便。

/* <color> values */
text-decoration-color: currentColor;
text-decoration-color: red;
text-decoration-color: #00ff00;
text-decoration-color: rgba(255, 128, 128, 0.5
text-decoration-color: transparent;

/* Global values */
text-decoration-color: inherit;
text-decoration-color: initial;
text-decoration-color: unset;

CSS不提供为每种线类型指定唯一颜色的直接机制。然而，这种效果可以通过嵌套元素实现：即对每个元素应用不同的线条类型（通过text-decoration-line属性），并以每个元素为基础指定线条颜色（通过text-decoration-color属性）来实现。
