Question

目前，当我将鼠标悬停在父母身上时，我网站上的子菜单会消失（请参阅www.fitnessdelicious.com上的导航菜单）。我已尝试过其他线程的几个解决方案，但到目前为止似乎没有任何工作。我知道我正在做什么html-和CSS-wise，但现在老老实实地不知道如何继续。请帮忙？下面的CSS片段。谢谢！

我添加了css类......它有效。

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

Answer 2

我没有为你回答，而是指出你可以在这里找到你的答案。在Mac上打开Chrome（Command Shift I）中的开发人员面板，然后右键单击您感到困惑的菜单栏并选择＆＃34; Inspect Element＆＃34;。

您将看到页面上的元素，并且对于每个选定的元素，您将在样式选项卡中看到应用于它的样式。

举个例子：只需快速浏览一下，我就会看到一种颜色应用于导航图标类白色。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，现在你需要找到红色的设置位置。查看元素列表和样式选项卡，您就可以找到它。

Answer 4

您还可以使用一个伪元素之前或之后创建一些透明的填充。这样，您可以延长商品的长度。
