</html>i want this code to onclick toggle class and when i refresh the page those toggled class remain same as they were before reloading the page with localstorage. so can someone check what's wrong with this code. help me with something similar/alternative to this one. thanks for reading this.
Details:-
i want this code to work as (onclick class change + saved with cokies/localstorage/or anything) so whenever i refresh or reopen the page it would be same class as it was when i left. or some alternative code that works same.
I fixed your code
if( localStorage.getItem("color") == "black" ) {
{
let element = document.getElementsByTagName("body");
element.classList.toggle("bdark");
}
{
let element = document.getElementById("theader");
element.classList.toggle("hdark");
}
{
let element = document.getElementById("sh");
element.classList.toggle("shh");
}
}
function myFunction() {
{
let element = document.getElementsByTagName("body");
element.classList="bdark";
}
{
let element = document.getElementById("theader");
element.classList="hdark";
}
{
let element = document.getElementById("sh");
element.classList="shh";
}
{
let hs = document.getElementById("hs");
}
let color;
if(localStorage.getItem("color") != "black") {
color = "black";
localStorage.setItem("color", color)
}
}.bdark {
background-color: #333;
color: white;
}
.hdark {
background-color: black;

}
.shh {
