如何在HTML / CSS中删除所选选项卡的边框？
我有用于创建水平选项卡栏的html和css，其中我有一些类和一个javascript函数，该函数根据特定选项卡的选择基本上更改选项卡：
function openPage(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";
}
// Get the element with id="defaultOpen" and click on it
document.getElementById("defaultOpen").click();
body {
font-family: Arial;
}
/* Style the tab */
.tab {
overflow: hidden;
border: 1px solid #ccc;
background-color: #f1f1f1;
}
/* Style the buttons inside the tab */
.tab button {
background-color: inherit;
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 {
background-color: #FFFFFF;
border-bottom-color: #FFFFFF;
}
/* Style the tab content */
.tabcontent {
display: none;
padding: 6px 12px;
border: 1px solid #ccc;
border-top: none;
}
/* Style the close button */
.topright {
float: right;
cursor: pointer;
font-size: 28px;
}
.topright:hover {
color: red;
}
当我运行它时，它工作正常，但是要删除的所选选项卡下方有一个下划线。有没有人有这个想法，如何在所选选项卡下删除它？

唯一的变化是.tab { overflow: hidden; border: 1px solid #ccc; border-bottom-color: transparent; background-color: #f1f1f1;}/* Style the buttons inside the tab */.tab button { background-color: inherit; float: left; border-bottom: 1px solid #ccc; outline: none; cursor: pointer; padding: 14px 16px; transition: 0.3s; font-size: 17px;} -

如果我错了，请告诉我，但你想看起来像这样吗？<html><head> <style> body { font-family: Arial; } /* Style the tab */ .tab { overflow: hidden; border: 1px solid #ccc; border-bottom: none; background-color: #f1f1f1; } /* Style the buttons inside the tab */ .tab button { background-color: inherit; 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 { background-color: #FFFFFF; border-bottom-color: #FFFFFF; } /* Style the tab content */ .tabcontent { display: none; padding: 6px 12px; border: 1px solid #ccc; border-top: none; } /* Style the close button */ .topright { float: right; cursor: pointer; font-size: 28px; } .topright:hover { color: red; } </style></head><body> <h2>Tabs</h2> <p>Click on the x button in the top right corner to close the current tab:</p> <div class="tab"> <button class="tablinks" onclick="openPage(event, 'Home')" id="defaultOpen">Home</button> <button class="tablinks" onclick="openPage(event, 'AboutUs')">AboutUs</button> <button class="tablinks" onclick="openPage(event, 'Careers')">Careers</button> </div> <div id="Home" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Home</h3> <p>Home Page.</p> </div> <div id="AboutUs" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>AboutUs</h3> <p>AboutUs page.</p> </div> <div id="Careers" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Careers</h3> <p>Careers Page.</p> </div> <script> function openPage(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"; } // Get the element with id="defaultOpen" and click on it document.getElementById("defaultOpen").click(); </script></body></html> -

你可以像这样编写代码。elm.style.textDecoration = "none";
