For this Lab, build off the existing CSS, including its baseline grid and typographic (modular) scale, and design a mobile-scale form that uses only shades of gray (no solid borders) for the input regions. Favor an open design with plenty of padding and white space.
Then, set up the font-family with a robust font stack made up of commonly available system fonts. You might use a site like https://fonts.google.com to get yourself started.
