Useful resources

• CSS Filter Generator - This tool calculates the correct values of CSS filter property functions to generate a desired color. It helped me to change the color of svg icons on hover state.
• Autoprefixer - It saved a lot of time by generating browser prefixes.
• flip-clock - This repository helped me to get a hint on how to create animated flip cards and how to add a countdown to it. I just adapted the code to fit my needs on this challenge.
