/* ==================== GIF Background Enhancements ==================== */

/*
 * HOW TO CUSTOMIZE GIF SIZE AND SPEED:
 * 
 * 1. GIF SIZE CUSTOMIZATION:
 *    Change the values after the last "/" in background property:
 *    - "300px 300px" = 300px width, 300px height
 *    - "200px 200px" = smaller size
 *    - "500px 500px" = larger size
 *    - "50% 50%" = 50% of modal size
 *    - "contain" = fit entire GIF maintaining aspect ratio
 *    - "cover" = fill entire modal
 *    - "auto" = original GIF size
 * 
 * 2. GIF SPEED CUSTOMIZATION:
 *    GIF speed cannot be controlled by CSS. To change speed:
 *    - Edit the GIF file using tools like:
 *      * Online: ezgif.com, giphy.com
 *      * Software: Photoshop, GIMP, After Effects
 *    - Or replace with a different speed version of the same GIF
 *    - Speed is controlled by frame delay in the GIF file itself
 * 
 * 3. ALTERNATIVE SPEED CONTROL (using CSS animation):
 *    If you convert GIF to sprite sheet, you can control speed with CSS
