Here's My Css Code

@import url('https://fonts.googleapis.com/css?family=Ubuntu');


*{
    box-sizing: border-box;
}

body {
    background-color: #efedd6;
    font-family:'Ubuntu', sans-serif;
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;
    margin: 0;
    overflow-x: hidden;
}
h1 {
    margin: 10px;
}

.box {
    background-color: steelblue;
    color: #fff;
    display: flex;
    align-items: center;
    justify-content: center;
    width: 400px;
    height: 200px;
    margin: 10px;
    border-radius: 10px;
    box-shadow: 2px 4px 5px rgba(0, 0, 0, 0.3);
    transform: translateX(200%);
    transition: transform 0.4s ease;
}

.box:nth-of-type(even) {
    transform: translateX(-200%);  
}
.box.show {
    transform: translateX(0);
}

.box h2 {
    font-size: 45px;
}

Here's JavaScript

const boxes = document.querySelectorAll('.box')

window.addEventListener('scroll', checkBoxes)

checkBoxes()

function checkBoxes() {
   const triggerBottom = window.innerHeight / 5 * 4 

   boxes.forEach(box => { 
       const boxTop = box.getBoundingClientRect().top

       if(boxTop < triggerBottom) {
           box.classList.add('show')
       } else {
           box.classList.remove('show')
       }
   })
}
