将鼠标悬停在远离父项时子菜单消失 (css)

Question

目前，当我将鼠标悬停在父菜单上时，我网站上的子菜单会消失（请参阅 www.fitnessdelicious.com 处的导航菜单）。我已经尝试了其他线程中的几种既定解决方案，但到目前为止似乎没有任何效果。我对我正在做的 html- 和 CSS- 有一些想法，但现在老实说我不知道如何继续。请帮忙？ CSS 下面的片段。谢谢！

Answer 1

我不会为您解答，而是会指出您以后可以在哪里找到您的答案。在 mac 上 Chrome（Command Shift I）打开开发人员面板，然后右键单击您感到困惑的菜单栏和 select "Inspect Element".

您会看到页面上的元素，对于每个 selected 元素，您会在样式选项卡中看到应用到它的样式。

举个例子：快速浏览一下你的，我看到一种颜色被应用于白色的导航图标 class。当我单击以禁用它时，我看到其余文本显示为黑色。所以它就在那里，现在您需要找到设置红色的位置。查看元素列表和样式选项卡，您会找到它。

我添加了 css class ...有效。

#mainnav-menu a:link, #mainnav-menu a:visited{
display:inline-block !important;
}

您还可以使用 before 或 after 伪元素来创建一些透明填充。这样你就可以延长项目的长度。
