How to change the selected tab color when clicked in HTML-CodePudding

From this method I could implement a hover that change the color when mouse over at some tab. But I need to change the color permanently when someone clicked tab.

Ex: If someone clicked Page 1, the tab should change color, if someone clicked page 2 then the tab should change color and page 1 tab should change to the color it was..

Can someone suggest a method to implement this?

.wrapper {
  display: flex;
  position: relative;
  display: flex;
  width: 100%;
  height: 100%
}

.wrapper .sidebar {
  width: 220px;
  height: 100%;
  background: #4b4276;
  padding: 30px 0px;
  position: fixed;
  font-size: 15px;
  display: block;
  height: 100%;
  flex-shrink: 0;
}

.wrapper .sidebar h2 {
  color: #fff;
  text-transform: uppercase;
  text-align: center;
  margin-bottom: 30px;
  font-family: Helvetica;
}

.wrapper .sidebar ul li {
  padding: 15px;
  border-bottom: 1px solid #bdb8d7;
  border-bottom: 1px solid rgba(0, 0, 0, 0.05);
  border-top: 1px solid rgba(255, 255, 255, 0.05);
}

.wrapper .sidebar ul li a {
  color: #bdb8d7;
  display: block;
}

.wrapper .sidebar ul li a .fas {
  width: 25px;
}

.wrapper .sidebar ul li:hover {
  background-color: #594f8d;
}

.wrapper .sidebar ul li:hover a {
  color: #fff;
}

.wrapper .main_content {
  margin-left: 220px;
  width: calc(100% - 200px);
  display: block;
}

<div >
  <div >
    <h2 style="font-family: Verdana;"> Dashboard</h2>
    <ul>
      <li><a href="#"><i ></i> Home</a></li>
      <li><a href="page1.php"><i ></i> Page 1</a></li>
      <li><a href="page2.php"><i ></i> Page 2</a></li>
      <li><a href="page3.php"><i ></i>Page 3</a></li>
      <li><a href="page4.php"><i ></i> Page 4</a></li>
      <li><a href="page5.php"><i ></i> Page 5</a></li>>
    </ul>
  </div>
</div>

Thank in Advance!

This should be done on the backend but incase you don't want to alter your markup or simply wants a lazy approach, you can try something like this.

Get the current page using window.location.pathname
Select the li a element with the href value from point 1 above
Add a class like active to the matched element

let currentPage = window.location.pathname === '/' ? '/' : window.location.pathname.substring(1)
let pageLink = document.querySelector('.sidebar>ul>li>a[href="' currentPage '"]');
if(pageLink) pageLink.parentElement.classList.add('active')
