Create a random color toast notification

Nowadays, Pop-up or Toast notifications are used in almost all apps. A toast notification shows information that appears on some action performed and disappears after some time.

Let's start with a button to show a toast message

 <div id="container"></div>
 <button id="btn">Show Notification</button>

and put the style for the button

button {
  background-color: lightblue;
  padding: 1rem;
  border-radius: 5px;
  color: darkblue;
  border: none;
  font-family: inherit;
  cursor: pointer;
}

Now get the button element and attach the click function to it

const btn = document.getElementById("btn");
const container = document.getElementById("container");

btn.addEventListener("click", () => {
  generateToast();
});

let's write the actual toast code now

function generateToast() {
  //creating toast element and adding styling class
  const toast = document.createElement("div");
  toast.classList.add("toast");

  //assigning random background color to each toast
  var randomColor = Math.floor(Math.random() * 16777215).toString(16);
  toast.style.backgroundColor = "#" + randomColor;

  //assigning text to toast
  toast.innerText = "Hello there 👋🏼";
  container.appendChild(toast);

  //making toast disappear after 2s
  setTimeout(() => {
    toast.remove();
  }, 2000);
}

Also, add some nice styling to toast with animation

#container {
  position: fixed;
  bottom: 10px;
  right: 10px;
}
.toast {
  padding: 1rem;
  border-radius: 5px;
  margin: 10px;
  color: rgb(0, 0, 58);
  animation: fadein 0.5s, fadeout 0.5s 2.5s;
}
@keyframes fadein {
  from {
    bottom: 0;
    opacity: 0;
  }
  to {
    bottom: 30px;
    opacity: 1;
  }
}
@keyframes fadeout {
  from {
    bottom: 30px;
    opacity: 1;
  }
  to {
    bottom: 0;
    opacity: 0;
  }
}
