Cover image for Explore 'Gardens of the World': Interactive Web App Showcase
Gardens of the World: Full-Stack Web App I've always enjoyed gardens, and gardening too. There's this quote by Audrey Hepburn that says: “To plant a garden is to believe in tomorrow.". And, honestly, her 90s series has been such a great inspiration for this project. This Web App consists of four sections: Home, Gardens, Tips, and Seasons. I've included 9 popular gardens, from the UK to Mexico. If you click on a garden, you'll get a pop-up with some interesting facts about it. I'll leave you this video of the Seasons section. By pressing the button corresponding to a season, the background of the section changes color, along with the information. You can read the details here (https://contra.com/p/MFYcqO6q-gardens-of-the-world-full-stack-web-app?referralExperimentNid=DEFAULT_REFERRAL_PROGRAM&referrerUsername=ciro_8_390dd5gp).
