This JavaScript code snippet helps you to show a tooltip on the mouse position on a webpage. It uses clientX and clientY properties of the mouse event to get the x and y coordinates of the cursor then sets the top and left CSS properties of the tooltip element.

The tooltip comes with a simple box that appears when the user hovers over an element. You can integrate this snippet to display additional information about the element, such as a description or a link. Moreover, you can customize the tooltip element with additional CSS according to your needs.

How to Show Tooltip On Mouse Position in JavaScript

1. First, create a container for your image and tooltip. Use the following HTML structure as a starting point:

<div class="container">
    <div class="img-block shadow-effect">
        <img class="image" src="">
        <span id="tooltip">❤ Coffee</span>

2. Apply the necessary CSS styles to ensure the proper layout and appearance. You can customize the styles according to your website’s design:

@import url(;

.container {
    display: flex;
    flex-direction: column;
    justify-content: center;
    align-items: center;
    height: 95vh;
    width: 100%;

.img-block {
    max-height: 80%;
    width: auto;
    cursor: pointer;
    display: flex;
    justify-content: center;
    position: relative;

.image {
    max-height: 100%;
    width: auto;
    max-width: 100%

#tooltip {
    position: fixed;
    height: fit-content;
    width: fit-content;
    background-color: white;
    padding: 5px 12px;
    box-shadow: 0 0 2px rgba(0,0,0,0.2);
    border-radius: 5px;
    font-family: 'Open Sans';
    display: none;

.img-block:hover #tooltip {
    display: block;

.shadow-effect {
    -webkit-box-shadow:0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
       -moz-box-shadow:0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
            box-shadow:0 1px 4px rgba(0, 0, 0, 0.3), 0 0 40px rgba(0, 0, 0, 0.1) inset;
.shadow-effect:before, .shadow-effect:after {
    -webkit-box-shadow:0 0 20px rgba(0,0,0,0.8);
    -moz-box-shadow:0 0 20px rgba(0,0,0,0.8);
    box-shadow:0 0 20px rgba(0,0,0,0.8);
    -moz-border-radius:100px / 10px;
    border-radius:100px / 10px;
.shadow-effect:after {
    -webkit-transform:skew(8deg) rotate(3deg);
       -moz-transform:skew(8deg) rotate(3deg);
        -ms-transform:skew(8deg) rotate(3deg);
         -o-transform:skew(8deg) rotate(3deg);
            transform:skew(8deg) rotate(3deg);

3. Finally, integrate the following JavaScript code to enable the dynamic positioning of the tooltip based on the mouse cursor:

let toolTip = document.getElementById('tooltip');

window.addEventListener('mousemove', toolTipXY);

function toolTipXY(e) {
    let x = e.clientX,
        y = e.clientY; = (y + 20) + 'px'; = (x + 20) + 'px';

That’s all! hopefully, you have successfully created a functionality to display the tooltip on the cursor position using JavaScript. If you have any questions or suggestions, feel free to comment below.
