   MIS 2201 PHASE 1: PERSONAL WEBSITE STYLESHEET
   ==================================================================================
   
   FILE: style.css
   PURPOSE: Main stylesheet for your personal portfolio website
   
   WHAT THIS FILE DOES:
   - Controls all visual styling (colors, fonts, layouts, spacing)
   - Makes your website responsive (looks good on phones, tablets, desktops)
   - Creates animations and interactive effects
   - Ensures consistent design across all pages
   
   ================================================================================== 
   
   CSS BASICS FOR STUDENTS
   ==================================================================================
   
   CSS (Cascading Style Sheets) controls how your HTML looks. It uses "selectors"
   to target HTML elements and apply styles to them.
   
   ANATOMY OF A CSS RULE:
   ```
   selector {
       property: value;
       another-property: another-value;
   }
   ```
   
   EXAMPLE:
   ```
   h1 {
       color: red;
       font-size: 24px;
   }
   ```
   This makes all <h1> headings red and 24 pixels tall.
   
   ================================================================================== 
   
   CUSTOMIZING THIS STYLESHEET
   ==================================================================================
   
   YOU DON'T NEED TO MODIFY THIS FILE TO COMPLETE THE PROJECT!
   
   However, if you want to customize your website's appearance, here are the
   easiest ways to do it:
   
   1. CHANGE COLORS (See CSS Variables section below)
      - Scroll down to :root { } section
      - Change the color values
      - Example: Change --primary-color from #7a0019 to #ff0000 for red
   
   2. CHANGE FONTS
      - Find the --font-primary and --font-heading variables
      - Replace with different font families
      - Example: --font-primary: 'Arial', sans-serif;
   
   3. ADJUST SPACING
      - Modify the --spacing variables to make things closer or further apart
   
   4. CHANGE BORDER RADIUS
      - Adjust --radius variables to make corners more or less rounded
   
   Make changes carefully and test in your browser after each change!
   
   ================================================================================== 
   
   CSS VARIABLES (Custom Properties)
   ==================================================================================
   
   CSS Variables let you define values once and reuse them throughout the file.
   This makes it easy to change colors, fonts, or spacing in one place.
   
   HOW TO USE:
   - Define: --variable-name: value; (in :root)
   - Use: var(--variable-name) anywhere in the file
   
   EXAMPLE:
   ```
   :root {
       --my-color: blue;
   }
   
   h1 {
       color: var(--my-color);  (h1 will be blue)
   }
   ```
   
   TIP: Change the values below to customize your entire website's look!
