Need help from a UI/UX designer for the COVID weekend project

I have developed a web app as a weekend challenge. I have completed the backend and front end ( react component-wise ) but need a bit of help in HTML CSS design. I already have a layout and design figured need some help in implementing it using HTML, CSS , Bootstrap. (1-2 hours max someone with experience )

-> this App is basically a Web App for improving your speed reading skills. I love to give you credit for UI/UX side
