3 Column using HTML & CSS

I agree with the previous comment. This project looks really good, but I'd just add the media query in CSS and use the 'flexbox-direction' property with the attribute of 'column (https://developer.mozilla.org/en-US/docs/Web/CSS/flex-direction). Afterward, adjust margins and gaps as needed. I had this same issue, but with the desktop layout, so I had to use the media query and 'flex-direction' property with the attribute of 'row'. You can find good information on media queries here: https://www.w3schools.com/css/css_rwd_mediaqueries.asp

Happy coding :)

what i would do here is create a media query for mobile screen and with your .card-box you can flex-direction: column.. it should position your boxes in column. just adjust the gaps on it and its good. hope this helps :)
