grid and eval method

Hello, fajar! 👋

Congrats on finishing another challenge! Your solution responds well and looks good. Kudos for clicking effect on buttons. What I'd suggest you is:

• Your calculator isn't aligned to center. To achive that add these styles to your body since you're familiar with Flexbox:

display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
min-height: 100vh;

Good luck with that, have fun coding! 💪

your color modes are not staying selected I guess that is the first thing to work on

second you need to add in more logic into the calculator to prevent things like multiple ....... entered in a row
