位置：粘性按钮在 IE 11 中不起作用

Question

我需要使包含按钮的 div 具有粘性，以便当用户滚动屏幕时，该 div 中的按钮将保持在底部。

这样用户就不必一直向下滚动来单击按钮。

包含按钮的 div 一直到这里：

 <div class="form-group sticky-button-thing-not-working-on-ie">
    <div class="col-md-offset-2 col-md-10">
        <input type="submit" value="Save" class="btn btn-default" />
    </div>
</div>

 .sticky-button-thing-not-working-on-ie {
  position: sticky;
  bottom: 0;
  right: 0;
  background: rgba(0, 211, 211, 0.6);
}

</div>

使其具有粘性的 CSS 类（在 Firefox 上工作）：

 .sticky-button-thing-not-working-on-ie {
    position: sticky;
    bottom: 0;
    right: 0;
    background: rgba(0, 211, 211, 0.6);
}

但在 Internet Explorer 11 上同样不起作用。关于如何在 IE11 上使用相同的代码有什么帮助吗？

Answer 1

sticky 不适用于 IE11，但幸运的是，在这种情况下，您可以使用 fixed ，它适用于新旧浏览器。

 .sticky-button-thing-not-working-on-ie {
  position: fixed;                          /* added to support older browsers */
  position: sticky;
  bottom: 0;
  right: 0;
  background: rgba(0, 211, 211, 0.6);
}

你实际上可以删除 sticky ，因为它没有按预期使用。 sticky 出色，即当您将它放置在顶部边缘下方时，当向下滚动时它将随页面移动直到到达顶部边缘，它会停止并停留直到再次向上滚动。

旁注：边缘支持 sticky 从版本 16
