All solutions

It took much time from me due to some personal reason and some issue that I faced using (Toggle device toolbar ) that you can open it by clicking ( Ctrl + Shift + M ), you can't see the effect of 'overflow : hidden ' in CSS because it doesn't work using this tool (Toggle device toolbar) so I was thinking there is a problem in my code. It took much time from me to realize that I need to close the tool.

I think I have some issue in CSS file (media.css) like duplicated styles, I know must correct it but I'm very tired.

I will do better in my next challenges by avoiding my mistakes.

I made some changes like there is no warning message will show if "Number of People" field is equal to zero, you can't make it zero.

Any suggestion to make the design better ?

Are there any tips to improve the design ?
