固定位置不适用于 Modal Window

Question

我有 HTML 个 "Modal" 和 CSS。在 CSS 中，我定义了 modal-footer 和 modal-fixed-footer classes。 modal-fixed-footer class 不会导致项目 "stick" 到屏幕，它仍然滚动。

<div class="body-blackout"></div>
<button class="btn-big ripple ripple-effect popup-trigger" data-popup-trigger="one">
    Popup Trigger Two
</button>
<button class="btn-big ripple ripple-effect popup-trigger" data-popup-trigger="two">
    Popup Trigger Two
</button>
<div class="popup-modal" data-popup-modal="one">
    <div class="popup-modal-close"></div>
    <h5>Modal One Title</h5>
    <p>

Answer 1

也许你需要用到这个CSS:

.modal-fixed-footer {
    position: sticky;
    bottom: -45px !important;
}

但是考虑到您没有 post 您的 CSS 很难理解什么不起作用。

此外，我无法想象 class modal-fixed-footer 应该出现在哪里以及如何出现。
