Change active class when a menu item is clicked

Question

I'm trying to change the active class when I click one of the items in the menu , but how do I change the color on selected tab to another active tab and then remove the old one?

 .wdc-table-menu ul { list-style-type: none; margin: 0; padding: 0; overflow: hidden; background-color: #484A51; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li { float: left; }.wdc-table-menu li a { display: block; color: white; text-align: center; padding: 14px 16px; text-decoration: none; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li a:hover { background-color: #3A3B41; }.wdc-table-menu.active { background-color: #3A3B41; }.wdc-table-title { text-align: center; }.wdc-table-title p { color: #D3D3D9; font-size: 2rem;important: font-weight; bold; }

 <div class="wdc-table-menu"> <ul id="menu_wdc"> <li><a class="wdc_btn active" href="#">WDC</a></li> <li><a class="wdc-btn" href="#">History</a></li> <li><a class="wdc-btn" href="#">Components</a></li> </ul> </div>

Answer 1

You would wanna use JavaScript to achieve this. Like so:

 const links =document.querySelectorAll(".wdc-btn "); links.forEach(btn => btn.addEventListener("click",(e)=>{ e.preventDefault(); document.querySelector(".wdc-btn.active").classList.remove("active"); btn.classList.add("active") }));

 .wdc-table-menu ul { list-style-type: none; margin: 0; padding: 0; overflow: hidden; background-color: #484A51; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li { float: left; }.wdc-table-menu li a { display: block; color: white; text-align: center; padding: 14px 16px; text-decoration: none; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li a:hover { background-color: #3A3B41; }.wdc-table-menu.active { background-color: #3A3B41; }.wdc-table-title { text-align: center; }.wdc-table-title p { color: #D3D3D9; font-size: 2rem;important: font-weight; bold; }

 <div class="wdc-table-menu"> <ul id="menu_wdc"> <li><a class="wdc-btn active" href="#">WDC</a></li> <li><a class="wdc-btn" href="#">History</a></li> <li><a class="wdc-btn" href="#">Components</a></li> </ul> </div>

You can use pseudo-class :focus . Also an event onclick for remove .active :

 function myfunction(){ document.getElementById("active").classList.remove("active"); }

 .wdc-table-menu ul { list-style-type: none; margin: 0; padding: 0; overflow: hidden; background-color: #484A51; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li { float: left; }.wdc-table-menu li a { display: block; color: white; text-align: center; padding: 14px 16px; text-decoration: none; border-top-right-radius: 0.938rem; border-top-left-radius: 0.938rem; }.wdc-table-menu li a:hover { background-color: #3A3B41; }.wdc-table-menu li.active{ background-color: #ff0000; }.wdc-table-menu li a:focus{ /*here*/ background-color: #ff0000; }.wdc-table-title { text-align: center; }.wdc-table-title p { color: #D3D3D9; font-size: 2rem;important: font-weight; bold; }

 <div class="wdc-table-menu"> <ul id="menu_wdc" onclick="myfunction()"> <li><a id="active" class="wdc_btn active" href="#">WDC</a></li> <li><a class="wdc-btn" href="#">History</a></li> <li><a class="wdc-btn" href="#">Components</a></li> </ul> </div>
