I think the way to approach the challenge is good, I mean that the mobile-first workflow helps a lot of in gradually adding just the necessary styles and preventing it from becoming a huge css file. For the next time I will try to declare more utilities classes because I think they are useful for larger projects.
What challenges did you encounter, and how did you overcome them?The naming of the classes for HTML tags is always a problem for me, because I feel like I need to return to HTML file a lot of times just to remember the names, so I just declared the names based of what I see on the card.
What specific areas of your project would you like help with?I think that I need help on the images, because the document is always loading both, the desktop and the mobile images, I just declare a media query to display the desktop image and hide the mobile image on larger screens, but I don't think this is the right approach.
