如何创建悬停效果并带来 2 个不同的 <a href> 标签？

如何解决如何创建悬停效果并带来 2 个不同的 <a href> 标签？

就我而言，我想实现完全相同的目标，但不知道该怎么做。

.apply-button {
    position: absolute;
    margin-top: 8rem;
    border-radius: 5em;
    Box-shadow: 0 8px 4px 0 rgba(0,0.25);
    border-style: solid;
    border-width: 0.275rem;
    border-image-slice: 0;
    border-image-source: linear-gradient(to top,#0270bb,#c6e357,rgba(255,153,0.9));
    background-origin: border-Box;
    background-clip: content-Box,border-Box;
    background-image: linear-gradient(to bottom,#ffffff,#ffffff),linear-gradient(to top,0.9));
}

<a role="button" class="apply-button" href="#"><p>apply</p></a>

解决方法

试图理解你的问题，但没有得到你真正想要的：

这是实现悬停效果的示例代码。
