this project is about to open new tabs and learn something new or study using flash cards, but with the syntax of JavaScript, you can modify everything that you can need to improve your studies or just make a little change in your way of learning something cool!
I found inspirations from the extension of Codeacademy, you can download and installed from here: Codecademy extension
Make some variations or making a new one like mine using some intermediate skills of CSS and very simple of HTML but I have to say, you need have to know an intermediate level of JavaScript to finish your extension of tips tab.
In a few days, I am gonna upload the extension such that you can download and install in your browser, and maybe find some inspirations to make your own! and become a developer like me LOL.
