[Feat] Adding new projects and fixing typos

[c4dr-me]

Description

I'd like to add more projects like tip calculator app, four card section which are made using HTML, CSS, JS with proper semantic use and aria labels for screen reader with user friendly interface. Also, there is a typo in card 5 and further UI improvements
