Hi everyone. I finished my calculator. You can look at codepen.io. I would appreciate anyone who will test and evaluate my work.
wow that’s awesome nice try i really like what you’ve done back there thumb’s up
Here you go then:
injashkin your calculator:
I think its better if you change the color of the equal sine.
When you make an account, the calculator shows the final value twice.
About the division by 0 I say you the same thing that I said to stel: When you divide by 0 you can’t say is infinite, because currently its not defined if is infinite or other thing, so my advice is when you divide something by 0 put “Its not possible to divide by 0”.
Thanks for feedback! I was doing a project functionally similar to the https://codepen.io/freeCodeCamp/full/wgGVVX. There is also repeated twice the final value. As for zero, I agree, it needs to be changed. Although on the link the result is - infinity. I don’t bother with color. The main thing is functionality.
Nice job! 
- For mobile stuff, please go to pen settings -> html -> insert viewport meta tag -> save & close.
- On the display with what you typed, IMO the background should be a bit lighter:
- On the buttons, what about a different border?
Maybe 1px solid white? - Great job!
Thank You Steffan153.
As far as I understand, I have to enter the following: <meta name="viewport" content="width=device-width, initial-scale=1">?.
How about this background?
With the boundaries of the buttons I have not yet figured out, as they automatically sets Bootstrap. Can someone tell me?
Wow! Impressive functionality and style!
I love how you space you calculator’s buttons. Your colors are really great, too.
If you could put a green space at the top of the calculator’s screen to hide the previous step, that’d be great.
Sorry, forgot to update the code. How now?
Yes. 
Actually bootstrap does not set the button styles, since you didn’t use Bootstrap classes on it. Simply set border: 1px solid white on buttons.
Nice. 
When I do so, disappears the effect of pressing.
Anyone tell me why on the website http://projects.jinv.ru/projects/calculator/index.html this calculator has large numbers and buttons
and here codepen.io labels on buttons small
