My solution of a take home assignment for landing page development.
Implemented using TailwindCSS, Vanilla JavaScript, HTML, created CI/CD pipeline.
All elements are responsive including the carousel and tabs/accordion. Navbar mobile implementation was not required.
Requirements Specification:
“Convert the PSD to HTML that is provided below. The carousel should be responsive. On mobile, the tabs should be converted to an accordion. History, team - these are internal links in the page to their respective sections.”
