将内角曲线边框添加到活动菜单 [英] Add inner corner curved border to active menu
问题描述
我试图为活动/选择菜单创建内部弯曲边框。下面的片段是到目前为止我能做的最好的,方角不应该可见。来自google的解决方案似乎不帮助...请帮助我玩它。多谢你们!
body {background:#eee; width:90%; margin:20px auto} ul {margin:0; padding:0;} ul li {display:inline-block; list-style:none;位置:相对; vertical-align:bottom;} ul li a {padding:10px 15px;显示:block; line-height:25px; margin-bottom:-1px;} ul li.active a {background:#fff; border:1px solid #aaa; border-bottom:0; border-radius:5px 5px 0 0;} ul li.active:before,ul li.active:after {content:; position:absolute; bottom:-1px; width:10px; height:10px; border:solid #aaa;} ul li.active:before {left:-10px; border-radius:8px 0; border-width:0 1px 1px 0} ul li.active:after {right:-10px; border-radius:0 8px; border-width:0 0 1px 1px;}。content {border:1px solid #aaa; background:#fff; height:200px} < ul> < li>< a href =#>标签1< / a>< / li> < li class =active>< a href =#> tab2< / a>< / li> < li>< a href =#> tab3< / a>< / li> < li>< a href =#> tab4< / a>< / li>< / ul>< div class =content>< / div>
但我希望有一个更好的解决方案在那里...我使用活动 a的伪元素
创建一个白色边框隐藏尖角。
body {background:#eee; width:90%; margin:20px auto} ul {margin:0; padding:0;} ul li {display:inline-block; list-style:none;位置:相对; vertical-align:bottom;} ul li a {padding:10px 15px;显示:block; line-height:25px; margin-bottom:-1px;} ul li.active a {background:#fff; border:1px solid #aaa; border-bottom:0; border-radius:5px 5px 0 0;} ul li.active:before,ul li.active:after {content:; position:absolute; bottom:-1px; width:10px; height:10px; border:solid #aaa;} ul li.active:before {left:-10px; border-radius:50%0; border-width:0 1px 1px 0; box-shadow:1px 1px white;} ul li.active:after {right:-10px; border-radius:0 50%; border-width:0 0 1px 1px; box-shadow:-1px 1px white;}。content {border:1px solid #aaa; background:#fff; height:200px}
< ul> < li>< a href =#>标签1< / a>< / li> < li class =active>< a href =#> tab2< / a>< / li> < li>< a href =#> tab3< / a>< / li> < li>< a href =#> tab4< / a>< / li>< / ul> < div class =content>< / div>
UPDATE:我以前的答案需要更多的CSS,所以我编辑它。基于jbutler的答案,我想到添加 box-shadow
来隐藏角落。没有什么改变在原来的css我在这里,我只是添加了盒子阴影。更新了小提示这里。
I am trying to create an inner curved border for active/selected menu. Below snippet is so far the best I can do, the square corner shouldn't be visible. Solutions from google doesn't seem to help... Please help me play with it. Thanks guys!
body {
background:#eee;width:90%;margin:20px auto
}
ul {
margin: 0;
padding: 0;
}
ul li {
display: inline-block;
list-style: none;
position: relative;
vertical-align:bottom;
}
ul li a {
padding: 10px 15px;
display: block;
line-height: 25px;
margin-bottom:-1px;
}
ul li.active a {
background:#fff;
border:1px solid #aaa;
border-bottom:0;
border-radius:5px 5px 0 0;
}
ul li.active:before,
ul li.active:after {
content:"";
position:absolute;
bottom:-1px;
width:10px;
height:10px;
border:solid #aaa;
}
ul li.active:before {
left:-10px;
border-radius:8px 0;
border-width:0 1px 1px 0
}
ul li.active:after {
right:-10px;
border-radius: 0 8px;
border-width:0 0 1px 1px;
}
.content {
border:1px solid #aaa;background:#fff;height:200px
}
<ul>
<li><a href="#">tab 1</a></li>
<li class="active"><a href="#">tab2</a></li>
<li><a href="#">tab3</a></li>
<li><a href="#">tab4</a></li>
</ul>
<div class="content"></div>
This is my solution so far. But I am hoping there is a better solution out there... I use the pseudo element of active a
to create a white border to hide the sharp corner.
body {
background:#eee;width:90%;margin:20px auto
}
ul {
margin: 0;
padding: 0;
}
ul li {
display: inline-block;
list-style: none;
position: relative;
vertical-align:bottom;
}
ul li a {
padding: 10px 15px;
display: block;
line-height: 25px;
margin-bottom:-1px;
}
ul li.active a {
background:#fff;
border:1px solid #aaa;
border-bottom:0;
border-radius:5px 5px 0 0;
}
ul li.active:before,
ul li.active:after {
content:"";
position:absolute;
bottom:-1px;
width:10px;
height:10px;
border:solid #aaa;
}
ul li.active:before {
left:-10px;
border-radius:50% 0;
border-width:0 1px 1px 0;
box-shadow: 1px 1px white;
}
ul li.active:after {
right:-10px;
border-radius: 0 50%;
border-width:0 0 1px 1px;
box-shadow: -1px 1px white;
}
.content {
border:1px solid #aaa;background:#fff;height:200px
}
<ul>
<li><a href="#">tab 1</a></li>
<li class="active"><a href="#">tab2</a></li>
<li><a href="#">tab3</a></li>
<li><a href="#">tab4</a></li>
</ul>
<div class="content"></div>
UPDATE: My previous answer requires more css so I edited it. Based on the answer of jbutler, I got the idea about adding box-shadow
to hide the corners. Nothing much changed on the original css I presented here, I just added the box-shadow. Updated fiddle HERE.
