Hello, i am currently trying to complete the responsive web design project : build a product landing page. My usual method of working is copy and paste the already working sample, make changes here and there to fit my need, and complete the challenge.
This time, however, this doesn’t seems to work. The sample source here uses some display:flex within it’s CSS, but when i copied the CSS to my personal codepen it just doesn’t seem to work : the elements are still displayed as block element, despite of the display:flex within the CSS code.
I also tried to copy to my laptop, still doesn’t work. Why? Do i miss something?
