无法将CSS动画限制在特定部分或div上

Question

以某种方式，我不能使此动画仅限于网页的一个特定部分。我不希望它显示在整个背景上，只想将其固定为一个div。

这是html代码

<div class="sp-container">
<div class="sp-content">
    <div class="sp-globe"></div>
    <h2 class="frame-1">Reliable</h2>
    <h2 class="frame-2">Fast</h2>
    <h2 class="frame-3">Responsive</h2>
    <h2 class="frame-4">Beautiful</h2>
    <h2 class="frame-5">
        <span>bla</span>
        <span>bla</span>
        <span>bla</span>
    </h2>
    <a class="sp-circle-link" > Merry go round</a>
</div>

这是CSS

此动画不是我制作的。我知道这很愚蠢。

Answer 1

它固定为一格。它固定在sp容器上。

如果您只想使一个部分具有动画效果，则可以将该部分包装在sp-container中，然后从其余内容中删除sp-container。如果将sp-container用于动画以外的其他内容，则可以仅从sp-container中删除动画元素，然后将其重新添加。

这是您的代码，其中动画已从sp容器中删除，并已添加到特定元素中，如果您希望在特定内容上使用动画，则可以使用以下任一方法：

<div class="animation-fade"></div>
<div class="animation-blur"></div>

还请注意，将h2包装在sp容器中时，某些元素（例如h2）会有动画延迟。因此，如果您不打算将动画与h2标签一起使用，则建议您消除动画延迟。
