This is my initial solution

I had a issue with the button. My button size doesn't remain the same despite me setting its width using grid-template-column to be static. Any sugestion on how to create the input and button. Should i use float, grid or flex. Any advice would be apreciated

I also struggled a bit with JavaScript. Do i use queryselector or getelementbyID. Which one is better or which one do you guys prefer?
