## Description
|
||
|
<section id="description">这很好,但它还不能正常工作。注意动画在<code>500ms</code>过后如何重置,导致按钮恢复为原始颜色。您希望按钮保持突出显示。这可以通过设置来完成<code>animation-fill-mode</code>属性<code>forwards</code> 。 <code>animation-fill-mode</code>指定动画完成时应用于元素的样式。您可以这样设置: <code>animation-fill-mode: forwards;</code> </section>
|
||
|
|
||
|
## Instructions
|
||
|
<section id="instructions">设置<code>button:hover</code>的<code>animation-fill-mode</code>属性<code>button:hover</code> to <code>forwards</code>以便当用户将鼠标悬停在按钮上时按钮保持突出显示。 </section>
