/* ====================================================================
   aaronhaze.css
   One external stylesheet shared by every page of my portfolio site.
   Author: Aaron M. Haze | CGS 2820C Web Page Development
   Order: 1) tag selectors, body first, then in the order they appear on the page
          2) ID selectors  3) class selectors
          4) media queries (mobile first: phone styles are the default)
   Updated October 12, 2026: table styles for the contact page
   (Assignment 10, Tables and Forms Part 1).
   Updated October 15, 2026: selected nav rule moved to the class section.
   Updated November 2, 2026: form control styles for the working contact form
   (Assignment 11, Tables and Forms Part 2).
   Updated November 2, 2026: code style for commands on the lab report page.
