1. Understanding Basics

First things first, let's understand basics. Parallax scrolling is when background of a webpage moves at a different speed than content. It's like background is furr away and content is closer, so when you scroll, background seems to move slower. It's a cool effect that can make your website look really professional, if you do it right.

    height: 100vh;
    overflow-x: hidden;
    perspective: 1000px;
}
.parallax-back {
    background-image: url;
    background-attachment: fixed;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
    position: relative;
    height: 100%;
    transform: translateZ scale;
    z-index: -1;
}
.parallax-content {
    position: relative;
    z-index: 2;
    color: white;
    text-align: center;
    padding-top: 20%;
    background-color: rgba;
}
