These are some templates which I learnt to build through some amazing YouTube videos
DesignCourse: This uses pure Vanilla JS and makes a scrolling effect of elements and not the whole screen
Filip: This uses only HTML and SCSS and makes a scrolling effect for the whole screen and a 3D effect
DevEd: This uses a variety of JS libraries and makes the image scrolling effect with that fade-in thing for elements, I am yet to complete this.
