我的.tab
周围有一个边框,活动.tab-content {
height:200px;
width:400px;
background-color: #aaa;
border:1px solid #000;
}
.tabs-container {
height:auto;
width:400px;
background-color:#aaabbb;
}
.tabs {
width:360px;
margin-left:20px;
}
.tab {
display:inline-block;
padding:5px 20px;
}
.tab.active {
border-left:1px solid #000;
border-right:1px solid #000;
border-top:1px solid #000;
border-bottom:transparent;
background-color: #aaa;
}
周围有相同的边框。我尝试在底部添加透明边框无济于事。
有没有办法,在两个边界重叠的情况下,有一个覆盖另一个?或者有更好的方法来实现这一目标吗?
这里有jsfiddle来显示我的基本设置。
<div class="tabs-container">
<div class="tabs">
<div class="tab active">This Tab</div>
<div class="tab">That Tab</div>
</div>
</div>
<div class="tab-content">
</div>

您可以使用伪元素创建底部边框,使其与背景颜色相同,并将其定位为覆盖暗线。
.tab.active:after {
content: '';
border-bottom: 10px solid #aaa;
position: absolute;
bottom: -1px;
left: 0;
width: 100%;
}
.tab-content {
height:200px;
width:400px;
background-color: #aaa;
border:1px solid #000;
}
.tabs-container {
height:auto;
width:400px;
background-color:#aaabbb;
}
.tabs {
width:360px;
margin-left:20px;
}
.tab {
display:inline-block;
padding:5px 20px;
}
.tab.active {
border-left:1px solid #000;
border-right:1px solid #000;
border-top:1px solid #000;
background-color: #aaa;
position: relative;
}
.tab.active:after {
content: '';
border-bottom:10px solid #aaa;
position: absolute;
bottom: -1px;
left: 0;
width: 100%;
}
&#13;
<div class="tabs-container">
<div class="tabs">
<div class="tab active">This Tab</div>
<div class="tab">That Tab</div>
</div>
</div>
<div class="tab-content">
</div>

或者只是将整个导航栏向下移动1px。
.tab.active {
border-left:1px solid #000;
border-right:1px solid #000;
border-top:1px solid #000;
background-color: #aaa;
position: relative;
bottom: -1px;
}
.tab-content {
height:200px;
width:400px;
background-color: #aaa;
border:1px solid #000;
}
.tabs-container {
height:auto;
width:400px;
background-color:#aaabbb;
}
.tabs {
width:360px;
margin-left:20px;
}
.tab {
display:inline-block;
padding:5px 20px;
}
.tab.active {
border-left:1px solid #000;
border-right:1px solid #000;
border-top:1px solid #000;
background-color: #aaa;
position: relative;
bottom: -1px;
}
/* .tab.active:after {
content: '';
border-bottom:10px solid #aaa;
position: absolute;
bottom: -1px;
left: 0;
width: 100%;
} */
