If so, please edit your post to include it in the Tell us what’s happening section.
Learning to describe problems is an important part of learning how to code.
Also, the more information you give us, the more likely we are to be able to help.
Fulfill each user story one at a time. If there’s something you don’t recall it’s fine to review the appropriate lesson or search the web.
When you’ve finished with the user stories style your page using CSS.
No one can remember everything.
If you didn’t race through the lessons, just answering to get to the next one, then you did learn something and you know how to look it up when you need it again.
Everyone has doubts when starting the first project. The projects are not just another challenge. Each one is meant to be a significant step in your progress. Every project you do will require research, planning, trial and error, and strengthening your skills beyond what you gained from the incremental challenges.
If you feel you need to go through the lessons again then by all means, do it. Take your time. Satisfy each challenge. Make some changes and see what happens. That will help you to understand what the lessons are teaching.
If you need help then please clarify “need some assistance” and “forgot everything I learned”. What don’t you understand about fulfilling the requirement for the first user story?
