Refactor site colors: grey background, white content frame, remove CSS variables and emojis

[Copilot]

Complete visual redesign: grey outer background (#a6a6a6), white centered content frame (#ffffff), unified text color (#4a4a4a), and removal of all CSS variables and emoji icons.

Changes

Colors & Layout

• Body background: #a6a6a6, site frame: #ffffff (1000px max-width centered)
• Unified text color #4a4a4a for body, links, nav, tables; headings use #333333
• Header background transparent so grey shows through outside content frame

Section Navigation

• Constrained to content width—white background only within centered container
• Sticky nav with transparency on scroll (rgba(255,255,255,0.9) + backdrop-filter)

CSS Refactor

• Removed all :root variables and var() usage—hardcoded values throughout
• Added -webkit-backdrop-filter prefix for Safari support
• Fixed overflow handling to target specific containers instead of html/body

Emoji/Logo Removal

• Removed .logo-icon from header, .footer-logo from footer
• Removed 📅📍🎥 icons from hero info items (replaced with text labels)
• Removed ✓ checkmarks from dropdown menus

You are editing a Jekyll (GitHub Pages) site. Apply the changes below. Follow instructions exactly.

IMPORTANT CONSTRAINTS

• Hardcode colors as literal hex values in CSS. Do NOT use CSS variables and do NOT define color profiles/tokens.
• Remove logos and emojis from header/footer/hero and anywhere else they appear (including icon spans like .logo-icon, emoji bullets, and footer “logo” glyphs).
• All body text (paragraphs, lists, tables, and nav links) must use ONE single text color (same hex everywhere). Headings can be slightly darker if needed, but keep them consistent too.

================================================================================

1. BACKGROUND / FOREGROUND COLORS (HARD-CODED)
   ================================================================================
   Goal: outside area (page background) is #a6a6a6 and the website foreground/content area is white.

• Set body background to #a6a6a6.
• The “site frame” (header container, hero inner, section nav container, content wrapper, footer container) must have white background (#ffffff) and be visually centered.
• Ensure there is no full-width white band across the entire screen behind the fixed header. Only the centered site frame should be white.

================================================================================
2) SINGLE UNIFIED TEXT COLOR

• Choose one text color hex (e.g. #4a4a4a) and apply it to:
  • body, p, li, td, th, links, nav links, dropdown items, buttons text, footer text
• Make sure links and nav items still look like links (underline on hover is fine), but keep the same text color.

================================================================================
3) HORIZONTAL NAVIGATION MUST NOT RENDER INTO BACKGROUND

Problem: section horizontal navigation appears wider than content and “spills” into the grey background.

Fix:

• The horizontal nav bar must be constrained to the exact content width (same width as .content-wrapper).
• The nav background must remain white, but ONLY inside the site frame width.
• If the sticky nav is position: fixed, create a centered wrapper so the fixed element does not stretch full width visually.
  • Example approach:
    • Keep an outer fixed wrapper full width for positioning,
    • Inside it, place a centered inner container with max-width identical to content,
    • Only the inner container has white background.

Also:

• Prevent horizontal overflow:
  • Ensure no element causes page-level horizontal scroll.

================================================================================
4) SCROLL TRANSPARENCY FOR HORIZONTAL NAV

• While scrolling, the horizontal nav should become slightly transparent (still readable) and remain within the content width.
• Keep transparency subtle (e.g. opacity ~0.9) and use minimal JS to add a class.
• Ensure transparency affects only the nav area inside the site frame (not full-width background).

================================================================================
5) REMOVE LOGOS AND EMOJIS

• Remove any logo icon/emoji from header:
  • Remove the logo icon element (.logo-icon) or any emoji characters used as branding.
• Remove footer logo emoji/icon (e.g. .footer-logo).
• Remove emojis used in info items (calendar/location icons, bullets, etc.) and replace with plain text.

================================================================================
6) REMOVE CSS VARIABLES AND REPLACE WITH HARDCODED VALUES

• Refactor the current CSS to remove :root and all var(--...) usage.
• Replace every var(...) with literal values already present in the file.
• Keep typography (Roboto stack) and spacing, but use hardcoded rem/px values.

================================================================================
7) SHOW AND VERIFY SCREENSHOTS

After implementing:

• Build/serve locally (Jekyll serve or the repo’s existing workflow).
• Take screenshots of:
  1. Home page at top (show header + hero + background edges)
  2. A workshop page showing the sticky horizontal nav within content width
  3. The same workshop page after scrolling (show nav transparency + no spill)
• Screenshots must clearly show:
  • grey background outside (#a6a6a6)
  • white foreground site frame
  • section nav constrained to content width
  • no emoji/logo icons

OUTPUT REQUIREMENT

• Provide a short list of files changed.
• Confirm the exact hex used for:
  • body background (#a6a6a6)
  • site foreground (#ffffff)
  • unified body text color (single hex)
• Include the screensh...

Thanks — direction looks close, but one key layout issue:

Right now the site-frame shows the grey page background (#a6a6a6) inside the main website area (between sections/cards). The entire “website area” (the centered container: header/hero/nav/content/footer) should be a single continuous foreground color (white), with the grey background visible only outside that fixed-width container.

Concretely:

• Keep body/page background = #a6a6a6.
• Make the full site container (same width everywhere) have background = #ffffff, so there are no grey bands/gaps appearing within the site frame.
• Ensure hero + content wrapper + footer all share the same white parent background, instead of separate white boxes floating on grey.

Once that’s done, the grey should only appear as the outer margin around the centered site frame, not inside it.
