When you start your web design journey, it's common to feel intimidated. You're scrolling your favorite website and see a feature - perhaps it's a carousel of testimonials or CSS animations on scroll. Then you think, "I wish my site had that!" And it can. All you have to know is how to clone content.
Trust me, I've been there. While building a project, I saw an image gallery on another site that I wanted to use. Instead of starting from scratch, I took a look at the website's code and cloned it to better understand how it works. From there, I used an updated, customized version in my project.
