/* 
After having problems with CSS, I decided to create a new CSS for each HTML file. 
I know that isn't optimal, but I wanted to keep the styles separate for clarity.
Now that I have a better understanding of CSS, I have at least combined the CSS for the Apache eCharts.

This is a modified, more focused version of the style guide provided to me 
for my official PowerBI reports on KYTC TRAK (https://trak.kytc.ky.gov/) 
I like the clean, modern look and feel of the dashboard 
and wanted to use it as a base for my personal projects.
