Recreating UI of popular websites is fun, today we are going to code the Wikipedia's tooltip !

If you prefer to watch the video version it's right here :

But first ...
What is a tooltip ?

A Tooltip is usually some context displayed by hovering a link, a button or an icon.

Let's do it, step by step.

1. Create the tooltip and the links.

The links :

  <span class="tooltip"><a href="#">Tooltip1</a></span>
  <span class="tooltip"><a href="#">Tooltip2</a></span>
  <span class="tooltip"><a href="#">Tooltip3</a></span>

The tooltip :

<div class="tooltip-container">
        Lorem ipsum, dolor sit amet consectetur adipisicing elit. Libero tenetur non laborum dolorem laboriosam quo quibusdam assumenda dolores eveniet. Ipsum?
</div>

Style it, with position absolute, to make it easyer to place.

.tooltip-container {
  width: 425px;
  min-height: 200px;
  padding: 15px;
  font-size: 25px;
  background: white;
  box-shadow: 0 30px 90px -20px rgba(0,0,0,0.3);
  position: absolute;
  z-index: 100;
  display: none;
  opacity: 0;
}
.fade-in {
  display: block;
  animation: fade 0.2s linear forwards;
}
@keyframes fade {
  0% {
    opacity: 0;
  }
  100% {
    opacity: 1;
  }
}

Notice the lovely animation, to display from none to block and then animate from opacity 0 to 1 ! ♥

2 Animate with JavaScript.

Take all the links, and the tooltip container.

const tooltips= Array.from(document.querySelectorAll(".tooltip"));
const tooltipContainer = document.querySelector(".tooltip-container");

Listen to mouseenter and mouseout on every link and place the tooltip where the mouse is.

tooltips.forEach((tooltip) => {
  tooltip.addEventListener("mouseenter", (e) => {

    tooltipContainer.classList.add("fade-in");
    tooltipContainer.style.left = `${e.pageX}px`;
    tooltipContainer.style.top = `${e.pageY}px`;

  });

  tooltip.addEventListener("mouseout", () => {
    tooltipContainer.classList.remove("fade-in");
  });
});

Hurray, we made it !
If you want to add custom text for each link to the tooltip, I'm showing it in the video, I don't want to make too long article.
