[英]How do I draw a specific border in CSS?
我想做一个这样的边界:
“标签”是一个li
标签,例如:
<ul>
<li>one</li>
<li>two</li>
<li>three</li>
</ul>
下面的框是这样的div
元素:
<div class="main-container">
</div>
我这样尝试过:
li{
border-top: 1px solid red;
border-left: 1px solid red;
border-right: 1px solid red;
}
div{
border: 1px solid red;
}
但是,这两个边界重叠并且令人作呕。
我想避免使用table-cell
方法,因为不可能通过错误地计算面积来设计反应型。
套用border-bottom:1px white solid;
到您的活动标签并增加其padding-bottom
。 现在,使用z-index
对其进行调整。 而已 :)

这可能会有所帮助
function openCity(evt, cityName) { var i, tabcontent, tablinks; tabcontent = document.getElementsByClassName("tabcontent"); for (i = 0; i < tabcontent.length; i++) { tabcontent[i].style.display = "none"; } tablinks = document.getElementsByClassName("tablinks"); for (i = 0; i < tablinks.length; i++) { tablinks[i].className = tablinks[i].className.replace(" active", ""); } document.getElementById(cityName).style.display = "block"; evt.currentTarget.className += " active"; }
/* Style the tab */ .tab { overflow: hidden; } /* Style the buttons inside the tab */ .tab button { background-color: white; float: left; border: none; outline: none; cursor: pointer; padding: 14px 16px; transition: 0.3s; font-size: 17px; } /* Change background color of buttons on hover */ .tab button:hover { background-color: #ddd; } /* Create an active/current tablink class */ .tab button.active { border-left:1px solid red; border-top:1px solid red; border-right:1px solid red; border-bottom:1px solid white; } /* Style the tab content */ .tabcontent { display: none; padding: 6px 12px; border: 1px solid red; margin-top:-1px; }
<p>Click on the buttons inside the tabbed menu:</p> <div class="tab"> <button class="tablinks active" onclick="openCity(event, 'London')">London</button> <button class="tablinks" onclick="openCity(event, 'Paris')">Paris</button> <button class="tablinks" onclick="openCity(event, 'Tokyo')">Tokyo</button> </div> <div id="London" class="tabcontent" style="display:block"> <h3>London</h3> <p>London is the capital city of England.</p> </div> <div id="Paris" class="tabcontent"> <h3>Paris</h3> <p>Paris is the capital of France.</p> </div> <div id="Tokyo" class="tabcontent"> <h3>Tokyo</h3> <p>Tokyo is the capital of Japan.</p> </div>
<div class="main-container">
<ul>
<li class="list-item active">one</li>
<li class="list-item ">two</li>
<li class="list-item ">three</li>
</ul>
</div>
<script>
$('ul li.list-item').click(function(){
$('ul li.list-item').removeClass('active');
$(this).addClass('active');
});
</script>
