JavaScript Code: script.js

var onlinecheckplatform;
var agent = navigator.userAgent.match(/(opera|chrome|safari|firefox|msie)/?s*(.?d+(.d+)*)/i);
if (navigator.userAgent.match(/Edge/i) || navigator.userAgent.match(/Trident.*rv[ :]*11./i)) {
    onlinecheckplatform = "msie";
}
else {
    onlinecheckplatform = agent[1].toLowerCase();
}
if (document.getElementsByClassName(onlinecheckplatform).length > 0)
    document.getElementsByClassName(onlinecheckplatform)[0].classList.add('active');

jQuery Detect Browser

$(document).ready(function() {
    var onlinecheckplatform;
    var agent = navigator.userAgent.match(/(opera|chrome|safari|firefox|msie)/?s*(.?d+(.d+)*)/i);
    if (navigator.userAgent.match(/Edge/i) || navigator.userAgent.match(/Trident.*rv[ :]*11./i)) {
        onlinecheckplatform = "edge";
    }
    else {
        onlinecheckplatform = agent[1].toLowerCase();
