A simple js calculator project feedback

hello everybody ,
i created this little bit of a project , but i couldn’t think about or find any good ideas for what’s related to css , so i ended up with this simple layout .

i would appreciate any feedback , especially about the layout part .
here’s the link to the live App

as well as the git hub repo

The calculator is beautiful but as mentioned l0609890 about the background.

I want to pay your attention to the operations with zero:
you’ve for example 9*0 = 9 and 5/0 = 5 try to fix it.
Also sqrt doesn’t work

Good luck

alright i changed things , how does it look and behaves now ?

well it works fine but for me the look of the previous calculator was better, my suggestion is to keep the previous calculator look and change the background.
