four-card-feature-section-master using flexbox & grid

Hi every body😊

welcome to my new solution

I added some animation for appearing cards using jquery-appear and isInViewport plugins. when cards are on viewport isInViewport recognizes and helps them appear, when scrolling down and reaching to other cards jquery-appear is useful to make them show. I used grid for the layout of web.

It would be kind of you if check my codes and see if they are readable and easy to understand and did I use article tag in a right place?🌷🌷🌷

what is difference between section tag and article tag and their usage?
