@import url("https://fonts.googleapis.com/css2?family=Poppins:wght@300&display=swap");

* {
  margin: 0;
  padding: 0;
}
body {
  background-color: #eec0c6;
  background-image: linear-gradient(315deg, #eec0c6 0%, #7ee8fa 74%);
  color: #002999;
  font-family: "Poppins", sans-serif;
  overflow-x: hidden;
}
html {
  scroll-behavior: smooth;
}
.footer {
  background: #002999;
  color: white;
  display: flex;
  align-items: center;
  justify-content: center;
  cursor: pointer;
}
footer {
  margin: 0;
  text-align: center;
  display: flex;
  align-items: center;
  justify-content: center;
  width: 100vw;
}
/* Custom Scroll Bar */

::-webkit-scrollbar {
  width: 10px;
}

::-webkit-scrollbar-track {
  background-color: #fff;
  border-radius: 5px;
}

::-webkit-scrollbar-thumb {
  background-color: #00d9bf;
  border-radius: 5px;
}
Enter fullscreen mode Exit fullscreen mode

Then, finally add JS
First add the jQuery link
( if you are using a code editor then add into the HTML file in the bottom after your script.js
jQuery Link: https://code.jquery.com/jquery-3.3.1.min.js
Or
If you are using codepen add in is section if you don't know read this post:

//Get the button:
const footer = document.getElementById("footer");

$("#footer").on("click", function () {
  $(window).scrollTop(0);
});
Enter fullscreen mode Exit fullscreen mode

Explanation:
First Getting the Button

//Get the button:
const footer = document.getElementById("footer");
Enter fullscreen mode Exit fullscreen mode

next adding Event Listener (Click Obviously) to it
then reseting the scroll value to 0

//Get the button:
$("#footer").on("click", function () {
  $(window).scrollTop(0);
});
Enter fullscreen mode Exit fullscreen mode

That's it

Happy Coding 😃.
Bye 👋 have a good day 😊

Why use jQuery when there is a pure CSS solution ?

<body id="main">
    <div style="height: 2000px;">
      Scroll down
    </div>
    <a href="#main">Go to top</a>
</body>
Enter fullscreen mode Exit fullscreen mode

if you need smooth scroll

* {
       scroll-behavior: smooth;
  }
Enter fullscreen mode Exit fullscreen mode

I know this but I'm not satisfied with this because when I use this it adds a #idname in the url but in my solution it's not adding anything in my url

Then this is a single line PURE JS solution :D

<a onclick=" window.scrollTo(0,0);">Go to top</a>
Enter fullscreen mode Exit fullscreen mode
