First we’ll start with creating the structure of the Minion Eyes Follow Mouse Cursor project for that as you can see the above code we have used all the necessary elements & attributes to setup the structure. Let us know code the CSS part to add styling and aligned the tags.

CSS Code for Minion Eyes Follow Mouse Cursor

body {
  padding: 0;
  margin: 0;
  background-color: #f5d60e;
}
.container {
  width: 100vw;
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
}
.container:before {
  content: "";
  position: absolute;
  width: 100%;
  height: 4em;
  background-color: #231f1e;
  transform: translate(-50%, -50%);
  top: 50%;
  left: 50%;
  z-index: -1;
}
.eyes-wrapper {
  display: flex;
}
.eyes-wrapper:before {
  content: "";
  position: absolute;
  width: 26em;
  height: 6em;
  background-color: #a8a7ac;
  margin: auto;
  left: 0;
  right: 0;
  top: 0;
  bottom: 0;
  z-index: -1;
}
.eye {
  width: 10em;
  height: 10em;
  border: 15px solid #a6a4ad;
  background-color: #ffffff;
  border-radius: 50%;
}
.eyeball {
  height: 3.2em;
  width: 3.2em;
  background: radial-gradient(#271e1e 35%, #935a29 37%);
  border-radius: 50%;
  margin: 0.2em 3.5em;
  position: relative;
}
.eyeball:before {
  content: "";
  position: absolute;
  background-color: #ffffff;
  height: 0.7em;
  width: 0.5em;
  border-radius: 50%;
  top: 13px;
  left: 13px;
  transform: rotate(45deg);
}

Second comes the CSS code, which is mentioned above in that we have styled for the structure we have padded as well as aligned the Minion Eyes Follow Mouse Cursor project so that it is properly situated and doesn’t get messy with suitable CSS elements. Now we have created the structure using HTML and styled the webpage using CSS its time to add the functionality using JavaScript in this project.

JavaScript Code for Minion Eyes Follow Mouse Cursor

//Selecting the eye div
let eye_ref = document.querySelectorAll(".eye");

//mousemove for devices with mouse aand touchmove for touchcreen devices
let events = ["mousemove", "touchmove"];

//Check for touch screen
function isTouchDevice() {
  try {
    document.createEvent("TouchEvent");
    return true;
  } catch (e) {
    return false;
  }
}

//Same function for both events
events.forEach((eventType) => {
  document.body.addEventListener(eventType, (event) => {
    eye_ref.forEach((eye) => {
      /* getBoundingClientRect() method returns the position relative to the viewport */
      let eyeX = eye.getBoundingClientRect().left + eye.clientWidth / 2;
      let eyeY = eye.getBoundingClientRect().top + eye.clientHeight / 2;

      /* ClientX and ClientY return the position of clients cursor from top left of the screen*/
      var x = !isTouchDevice() ? event.clientX : event.touches[0].clientX;
      var y = !isTouchDevice() ? event.clientY : event.touches[0].clientY;

      /* 
    Subtract x position of mouse from x position of eye and y position of mouse from y position of eye.
    Use atan2(returns angle in radians)
    */

      let radian = Math.atan2(x - eyeX, y - eyeY);
      //Convert Radians to Degrees
      let rotationDegrees = radian * (180 / Math.PI) * -1 + 180;
      //Rotate the eye
      eye.style.transform = "rotate(" + rotationDegrees + "deg)";
    });
  });
});

Last stage of the project the JavaScript in which we have added the logical and coded as per the requirement with some conditions. In this script we have defined the eyes of minion and pass on some functions so that it follows the cursor on the user action and make the project functioning.
