Dont worry about “not remembering” - you wont remember a lot of stuff in the modules. If you were designing your own projects you would need to search the documentation / google for what parameters you need.
“I never commit to memory anything that can easily be looked up in a book” - Albert Einstein
Practice is the key, if you practice your skills they will be embedded much better than just reading the materials, plus you will have something more to show for it.
you dont need confidence, not really, you just need to keep moving, building projects and aiming to improve. Confidence will come later.
The project looks great, good use of colour and gradients. My image doesnt load, but i have a very poor internet connection. Its also showing an error saying its not centered within its element.
