2. The necessary styles for the toast popup.

.toast {
  cursor: pointer;
  box-sizing: border-box;
  display: none;
  width: 100%;
  max-width: 640px;
  font-size: 0.825em;
  border-top-right-radius: 5px;
  border-top-left-radius: 5px;
  background: #ffffff;
  box-shadow: 0 2.8px 2.2px rgba(0, 0, 0, 0.02), 0 6.7px 5.3px rgba(0, 0, 0, 0.028), 0 12.5px 10px rgba(0, 0, 0, 0.035), 0 22.3px 17.9px rgba(0, 0, 0, 0.042), 0 41.8px 33.4px rgba(0, 0, 0, 0.05), 0 100px 80px rgba(0, 0, 0, 0.07);
  -webkit-transition: 0.2s ease-in;
  transition: 0.2s ease-in;
}
@media (min-width: 640px) {
  .toast {
    border-radius: 5px;
    margin-bottom: 0.5em;
  }
}
.toast--active {
  display: -webkit-box;
  display: flex;
  -webkit-animation: slidein--bottom 0.5s cubic-bezier(0.68, -0.55, 0.265, 1.55) forwards;
          animation: slidein--bottom 0.5s cubic-bezier(0.68, -0.55, 0.265, 1.55) forwards;
}
.toast__container {
  box-sizing: border-box;
  padding: 0em 1em;
  position: fixed;
  width: 100%;
  max-width: 640px;
  margin: 0 auto;
  display: -webkit-box;
  display: flex;
  -webkit-box-orient: vertical;
  -webkit-box-direction: normal;
          flex-flow: column;
  bottom: 0;
  left: 0;
  right: 0;
  -webkit-box-align: center;
          align-items: center;
  -webkit-box-pack: center;
          justify-content: center;
}
@media (min-width: 640px) {
  .toast__container {
    padding: 0 1em;
  }
}
@media (min-width: 1024px) {
  .toast__container {
    left: initial;
    right: 0;
  }
}
.toast__icon {
  height: 60px;
  width: 60px;
  box-sizing: border-box;
  padding: 1em;
  display: none;
  -webkit-box-align: center;
          align-items: center;
  -webkit-box-pack: center;
          justify-content: center;
}
.toast__icon svg {
  height: 100%;
}
@media (min-width: 640px) {
  .toast__icon {
    display: -webkit-box;
    display: flex;
  }
}
.toast__icon ~ .toast__content {
  padding: 1em;
}
@media (min-width: 640px) {
  .toast__icon ~ .toast__content {
    padding: 1em 1em 1em 0;
  }
}
.toast__content {
  box-sizing: border-box;
  padding: 1em;
}
.toast__content h2 {
  margin: 0 0 0.25em 0;
  padding: 0;
  font-size: 1.2em;
}
.toast__content p {
  margin: 0;
  padding: 0;
  font-size: 1em;
}
@-webkit-keyframes slidein--bottom {
  0% {
    opacity: 0;
    -webkit-transform: translateY(100%);
            transform: translateY(100%);
  }
  100% {
    opacity: 1;
    -webkit-transform: translateY(0);
            transform: translateY(0);
  }
}
@keyframes slidein--bottom {
  0% {
    opacity: 0;
    -webkit-transform: translateY(100%);
            transform: translateY(100%);
  }
  100% {
    opacity: 1;
    -webkit-transform: translateY(0);
            transform: translateY(0);
  }
}

3. Create a trigger to display the toast notification.

<button class="toast__trigger">Info Toast</button>

4. Enable the trigger button to toggle the toast notification.

const toasts = document.querySelectorAll(".toast");
const toastTriggers = document.querySelectorAll(".toast__trigger");
toastTriggers.forEach((trigger, index) => {
  let toastTimeout;
  trigger.addEventListener("click", () => {
    toasts[index].classList.add("toast--active");
    toastTimeout = setTimeout(() => {
      toasts[index].classList.remove("toast--active");
    }, 3500);
  });
  toasts[index].addEventListener("click", () => {
    toasts[index].classList.remove("toast--active");
    clearTimeout(toastTimeout);
  });
});

5. Create your own notification types:

<div class="toast toast--warning" role="alert" aria-live="assertive" aria-atomic="true">
  <div class="toast__icon">
    <svg aria-hidden="true" focusable="false" data-prefix="fas" data-icon="exclamation-circle" class="svg-inline--fa fa-exclamation-circle fa-w-16" role="img" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512">
