What did you find difficult while building the project?
One of the biggest challenges was creating number-only inputs. I wasn't too familiar with Regex, but with a bit of trial and error, I believe the expressions I implemented work well enough.
Which areas of your code are you unsure of?
My implementation for responsive styling could use a bit of work. I think I was trying to account for too many viewports, and I ended up getting lost in my own code. What is currently there seems OK, but I think I could have found better solutions.
The other area I'm not sure of is displaying the values for the total and tip values per person. Large numbers will lead to overflow, and I wasn't sure if I wanted to decrease the font size in accordance to the amount of numbers in the string, or just add trailing ellipses.
Do you have any questions about best practices?
How would you tackle responsive layouts? Would you consider display width only, or display height as well?
