i used flexbox and css in vs code

Everything looks perfect but try to maintain the typography, like the heading "Improve your front-end skill.." was actually covered in two-lines. This could be achieved either by decreasing the font-size or increasing the width. And also the background, try to change it to the same color. Rest everything looks perfect. All the best!

It looks fine. But spend some time to refactor the code. For example, implement colors in right way.
