HTML,CSS, Figma

Just some more practice using Figma specs. Feels frustrating sometimes in that, doesn't always feels consistent to CSS conventions?? and in making changes with the responsiveness I found a few instances where it felt they just change the parent-child container relationship entirely and in a manner that doesn't feel reasonable/necessary. Invariably I'm almost finding the entire thing to be an absolute/left/top game and in some ways container/divs be damned, which doesn't really feel right. Would appreciate advice with anyone experienced in the design conversion process, or just any feedback/suggestions in general!
