Mobile first sketched in Figma, used HTML and CSS (Flexbox and Grid)

Will be more than glad to hear opinions regarding this project. Comparing with template project didn't managed to 'convert' header part to more bold/wide view but still seems good for me, "media" query to change the grid starting from 640px wide Basic prototype prepared in Figma (https://www.figma.com/file/C0hC17jUwmA718PuqotJjj/four-card-feature-section?node-id=0%3A1) - still learning how to use it.
