Calculator

About

This is a simple calculator app, written in JavaScript, and using FlexBox and CSS Grid for layout. I coded logic for the following:

Basic calculations.
Making sure successive decimal points can't be added.
Enabling calculations to be chained rather than just having a simple calculation using one operator (addition, subtraction, multiplication or division).
If operator buttons are pressed in succession, only the last one pressed is used in the calculation.
