Yes, I included this same website because of its cool features: it’s got authentication, a case studies (blog posts) management dashboard, beautiful responsive behavior, and an images upload system with server-side validation.
I used the most traditional stack to build it: HTML, CSS, JavaScript, MySQL and PHP. Most effects and transitions are written in CSS, tho I added some entrance animations here and there with AOS, a FOSS JavaScript library.
Its development helped me solidify skills (like BEM, SEO, authentication) with which build your next successfull website.
