Help with some finishing touches on my calculator project

I enclosed my calculator in it’s on container div. At some point, (can’t remember when exactly) it disappeared. I’m trying to add a drop shadow to this to make it pop a bit from the page, however my css for this isn’t appearing.

This would be much easier to diagnose if you could provide your code in CodePen, or at least link to your code in a repo.

2. I want to make sure I understood the user story correct for chaining operations. Lets say you wanted to calculate 2+42. With my calc you would enter the 2+4 and when you pressed * it would sum, then allow you to multiply this by 2; for an answer of 12. Is this ok, or are you supposed to be able to enter the entire operation 2+42, and it would then deal with proper order of operations and give an answer of 10?

This sort of implementation detail is entirely up to you. See this post:

Note On Calculator Logic: It should be noted that there are two main schools of thought on calculator input logic: immediate execution and formula logic (our example utilizes formula logic and observes order of operation precedence, immediate execution does not). Either is acceptable, but please note that depending on which you choose, your calculator may yield different results than ours for certain equations (see below example). As long as your math can be verified by another production calculator, please do not consider this a bug.

However if you were to continue multiplying a number up eventually the equation and answer start to run outside of the div. How could I prevent this?

Scientific notation comes to mind. Smaller font size is possible. You could also keep in mind the maximum size of numbers in JavaScript and leave room for up to 16 digits. First option is coolest, IMO, but the second is easiest.
