javascript - 如何使用活动菜单项解决此问题
问题描述
我在菜单项上的活动课程有一个小问题。我正在尝试在活动菜单项周围添加边框,例如在此悬停状态下,但是当我尝试将其添加到我的菜单项时,一切都搞砸了。我试图为活动课程实现的是:
.nav-menu {
list-style: none;
margin-top: 18px;
}
ol,
ul {
margin-top: 0;
margin-bottom: 10px;
}
.nav-menu li {
float: left;
border-left: 1px solid #1e3866;
padding: 5px 10px;
}
.snip1189 li {
display: inline-block;
list-style: outside none none;
padding: 0;
}
.snip1189 * {
-webkit-box-sizing: border-box;
box-sizing: border-box;
-webkit-transition: all 0.35s ease;
transition: all 0.35s ease;
}
.nav-menu li a {
color: #1e3866;
font-size: 13px;
}
.snip1189 a {
padding: 0.2em 0.5em;
margin: 0.2em 0;
display: block;
color: rgba(255, 255, 255, 0.5);
position: relative;
text-decoration: none;
}
.snip1189 a:before,
.snip1189 a:after {
height: 14px;
width: 14px;
position: absolute;
content: '';
-webkit-transition: all 0.35s ease;
transition: all 0.35s ease;
opacity: 0;
}
.snip1189 a:before {
left: 0;
top: 0;
border-left: 2px solid #e52b25;
border-top: 2px solid #e52b25;
-webkit-transform: translate(100%, 50%);
transform: translate(100%, 50%);
}
.snip1189 a:after {
right: 0;
bottom: 0;
border-right: 2px solid #1d3768;
border-bottom: 2px solid #1d3768;
-webkit-transform: translate(-100%, -50%);
transform: translate(-100%, -50%);
}
.snip1189 a:hover,
.snip1189 .current a {
color: #4a4949;
font-weight: bold;
}
.snip1189 a:hover:before,
.snip1189 .current a:before,
.snip1189 a:hover:after,
.snip1189 .current a:after {
-webkit-transform: translate(0%, 0%);
transform: translate(0%, 0%);
opacity: 1;
}
.active {
border-left: 2px solid #e52b25;
border-top: 2px solid #e52b25;
-webkit-transform: translate(100%, 50%);
transform: translate(100%, 50%);
}
<div class="pull-right">
<ul class="nav-menu snip1189">
<li><a href="#">Home</a></li>
<li><a href="#" class="active">About</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div>

解决方案
现在,您的.active
规则是将a
per 向下和向右平移transform: translate(100%, 50%);
。它还在左侧和顶部添加了一个纯红色边框,我不确定你是否打算这样做。我已删除您当前的.active
规则,并将以下 2 个选择器添加到当前悬停规则以显示 2 个边框。
.snip1189 a.active:before,
.snip1189 a.active:after,
.nav-menu {
list-style: none;
margin-top: 18px;
}
ol,
ul {
margin-top: 0;
margin-bottom: 10px;
}
.nav-menu li {
float: left;
border-left: 1px solid #1e3866;
padding: 5px 10px;
}
.snip1189 li {
display: inline-block;
list-style: outside none none;
padding: 0;
}
.snip1189 * {
-webkit-box-sizing: border-box;
box-sizing: border-box;
-webkit-transition: all 0.35s ease;
transition: all 0.35s ease;
}
.nav-menu li a {
color: #1e3866;
font-size: 13px;
}
.snip1189 a {
padding: 0.2em 0.5em;
margin: 0.2em 0;
display: block;
color: rgba(255, 255, 255, 0.5);
position: relative;
text-decoration: none;
}
.snip1189 a:before,
.snip1189 a:after {
height: 14px;
width: 14px;
position: absolute;
content: '';
-webkit-transition: all 0.35s ease;
transition: all 0.35s ease;
opacity: 0;
}
.snip1189 a:before {
left: 0;
top: 0;
border-left: 2px solid #e52b25;
border-top: 2px solid #e52b25;
-webkit-transform: translate(100%, 50%);
transform: translate(100%, 50%);
}
.snip1189 a:after {
right: 0;
bottom: 0;
border-right: 2px solid #1d3768;
border-bottom: 2px solid #1d3768;
-webkit-transform: translate(-100%, -50%);
transform: translate(-100%, -50%);
}
.snip1189 a:hover,
.snip1189 .current a {
color: #4a4949;
font-weight: bold;
}
.snip1189 a.active:before, /* added this line */
.snip1189 a.active:after, /* added this line */
.snip1189 a:hover:before,
.snip1189 .current a:before,
.snip1189 a:hover:after,
.snip1189 .current a:after {
-webkit-transform: translate(0%, 0%);
transform: translate(0%, 0%);
opacity: 1;
}
<div class="pull-right">
<ul class="nav-menu snip1189">
<li><a href="#">Home</a></li>
<li><a href="#" class="active">About</a></li>
<li><a href="#">Contact</a></li>
</ul>
</div>
