Product Preview Card Component Using Flexbox - Front End Mentor

I think everyone might be different. I start with the mobile format first then work my way up the different sizes. I usually work on the structure of the HTML as much as I can at first. Then move to the CSS. I think I start with global changes, like fonts and colors. Then I kind of work from top to bottom based on the HTML. So I style my body first, then header, divs and so on. Usually once I get to the CSS I may have to modify the HTML a little, so it becomes a bit back and forth sometimes. Overall, I think it may just be about finding a system for yourself and being consistent so that it doesn't feel random.
