I just finished displaying the numbers, adding if statement to not concatenate the 0, and using the parseFloat function to return a floating-point number. I'm taking a break, but once I finish this i'm planning to do the tic tac toe tutorial. Thank you for the help!

Hi bro thank you so much for your video. Could you limmi know how to make styles in CSS in alphabetic order? You have used some extinction. Is it possible in VS code

Hey Justin, I’ve been trying to figure out how to get the font to get smaller after 6 digits and stop at 9 digits. I know with <input> its easy to set maxlength to 9. Any tips how I could go about it the way you have coded the calculator? Thank you

Pls how can u turn the app into an offline app, or it can't?

[shloimesimchenager]

Why aren't you using id's in html?

[hrantsahakyan]

With your code I can not fix the problem, there you can not write more than 4 numbers

[javierbermudez]

which programing are you using? I been trying to build this with Visual Studio code and the grid wont come up for me

[frank]

I am not sure if I can make this by myself. It wasn't easy for me....
Honestly, I made some React and JavaScript clone projects and figured my programming skills weren't improving. I was only learning the technology not the programming skills.
Any advice please?
