悬停后保持下拉菜单打开(CSS)

问题描述

我创建了一个水平菜单，当您将鼠标悬停在某个菜单上时，将显示一个下拉菜单.一切都很好.但是，当您离开菜单项(使用下拉菜单)时，下拉菜单将消失.我了解这是因为您不再将鼠标悬停在上面，但是我该如何解决呢?注意:我不希望下拉菜单位于其正下方，我希望菜单项和下拉菜单之间有合理的距离(因为目前有).谢谢.

I have created a horizontal menu that when you hover an item, a drop down menu appears. This is all fine. However, when you leave the menu item (to use the drop down) the drop down disappears. I understand that this is because you are no longer hovering it, but how do I solve this? Note: I don't want the drop down menu directly below it, I want a reasonable gap between the menu item and drop down (as I have it at the moment). Thanks.

推荐答案

在'a'标记上，悬停时在其上添加高度或填充底部.您的'a'标签可能需要绝对放置，以使其高度不会影响标头的高度.

On the 'a' tag, add a height or padding-bottom to it on hover. Your 'a' tag might need to be positioned absolute so that its height won't affect the height of your header.

类似以下内容

.about-dropdown a:hover {
    padding-bottom: 30px; /*height dependent on the gap you want to fill*/
    position: absolute;
}
