Make mobile browser view full width

[Copilot]

• Explore repository structure and understand the CSS layout
• Identify the .site-frame class that controls width across desktop/mobile
• Add mobile media query to make .site-frame full width on mobile devices
• Take screenshots verifying both dropdowns visible
• Run code review
• Run CodeQL security scan (no issues - CSS only change)

Changes Made

Added CSS rule in the responsive design media query (@media (max-width: 768px)) to make .site-frame use width: 100% on mobile devices, ensuring the content spans the full width of the screen on mobile browsers while keeping the desktop view unchanged.

Screenshots

Desktop (unchanged - both dropdowns visible, centered with margins):

Mobile (now full width):

Original prompt

Change only the mobile brwoser view so it is full width of the screen, keep the web brower view as it is

In the screenshot it seems the web view is missing the seminar dropdown list. Cross check with full screen screenshots

You're right, my original test file was incomplete. Here are updated screenshots showing both "Workshop Year" and "AIEPS Seminar" dropdowns in the header:

Desktop (both dropdowns visible):

Mobile (full width, hamburger menu):

The CSS change only affects the mobile width - both dropdowns are present and functional.
