修复CSS导航栏按钮的浮动和方向

时间：2019-02-15 11:54:32

标签： html css drop-down-menu css-float submenu

我在使用此导航栏时遇到麻烦：https://jsfiddle.net/d6a7b3Ly/1/

1 -栏中有许多链接，悬停效果使下面的其他链接移到侧面，但是我不确定哪个填充效果在起作用以及如何解决它。

将RewriteRule .* page [QSD,R=301,L] 更改为0px可以解决此问题，但会使子菜单不起作用：

border-top

2 -我正在尝试使菜单的#nav .current a, #nav li:hover > a { background: #d1d1d1; /* for non-css3 browsers */ filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ebebeb', endColorstr='#a1a1a1'); /* for IE */ background: -webkit-gradient(linear, left top, left bottom, from(#ebebeb), to(#a1a1a1)); /* for webkit browsers */ background: -moz-linear-gradient(top, #ebebeb, #a1a1a1); /* for firefox 3.6+ */ color: #444; border-top: solid 1px #f8f8f8; -webkit-box-shadow: 0 1px 1px rgba(0, 0, 0, .2); -moz-box-shadow: 0 1px 1px rgba(0, 0, 0, .2); box-shadow: 0 1px 1px rgba(0, 0, 0, .2); text-shadow: 0 1px 0 rgba(255, 255, 255, .8); } 选项。我在csss中的right to left下更改了float: right;，并在#nav li {中添加了整个html，但是2级子菜单仍然朝左打开，应该是对的。我测试了CSS的一些更改，但没有任何改变。

这里是<div dir="RTL">的链接：https://jsfiddle.net/ct8kp6eo/1/

这是CSS中的浮动更改：

rtl navbar

要解决 问题，请添加padding-top: 7px以调整border-top，使版图损坏为#nav ul li:hover a, #nav li:hover li a。

您有重叠的 labels ，并要解决该问题，将z-index的{​​{1}}属性调整为1。

#nav li:hover > ul
body {
	font: normal .8em/1.5em Arial, Helvetica, sans-serif;
	background: #ebebeb;

}

答案 1 :(得分：0)

您正在悬停时添加边框顶部的实心1px。悬停时将其更改为0px即可正常工作。

#nav .current a, #nav li:hover > a {
	background: #d1d1d1; /* for non-css3 browsers */
	filter:  progid:DXImageTransform.Microsoft.gradient(startColorstr='#ebebeb', endColorstr='#a1a1a1'); /* for IE */
	background: -webkit-gradient(linear, left top, left bottom, from(#ebebeb), to(#a1a1a1)); /* for webkit browsers */
	background: -moz-linear-gradient(top,  #ebebeb,  #a1a1a1); /* for firefox 3.6+ */

	color: #444;
	/*border-top: solid 1px #f8f8f8;*/
    border-top: solid 0px #f8f8f8;      
	-webkit-box-shadow: 0 1px 1px rgba(0, 0, 0, .2);
	-moz-box-shadow: 0 1px 1px rgba(0, 0, 0, .2);
	box-shadow: 0 1px 1px rgba(0, 0, 0, .2);
	text-shadow: 0 1px 0 rgba(255, 255, 255, .8);
}

在悬停顶部添加1px会变得太多，这会使您的物品移动
