在我的水平菜单上非常奇怪的CSS问题

Question

我在顶部菜单栏上的prestashop网站上有一个非常奇怪的响应问题。你能帮我解决一下吗？

仅在介质宽度为600px时发生，问题是菜单子类别会自动降低。我不知道为什么，也不知道如何解决它......

这是代码

Answer 1

当浏览器的宽度增加时，会在某处运行一些JavaScript，将display：none作为内联CSS添加到元素中。问题是该脚本仅在浏览器宽度大于600px时才有效。要解决此问题，您必须将以下css应用于子菜单：

.sf-menu li ul {
    display: none;
}

.sf-menu li a:hover + ul {
    display: block !important;
}

在javascript中进行了一些修改，并且由于代码是混淆/优化的，因此很难说出你需要纠正的内容。 设置上面的CSS规则是一种橡胶补丁，您应该首先在源代码中找到发生修改的位置。也许你可以在你的问题中附上这段代码。

您的子菜单的生成方式也存在问题。那个＆＃34; novedades＆＃34;是＆＃34; Washi Tape＆＃34;中的一个ul元素。 li

我快速浏览了一下网站。我怀疑显示：没有人在那时消失。所以，这是你的css问题。它们现在对我来说太复杂了。建议将display：none！important放在其他规则上。
