Refactor CSS structure and implement responsive two-column layout

[deepdevjose]

Summary

• Split styles.css into 4 partials under css/partials/:
  • base.css (imports, variables, resets, global styles)
  • layout.css (page wrapper, sidebar/article, separator, icon-box, fade animation, two-column flex)
  • components.css (UI modules: cards, buttons, sidebar-info, navbar, sections…)
  • utilities.css (helpers, custom scrollbars, keyframes, media queries)
• Updated layout.css to:
  • Wrap all <article> in a .main-content container
  • At @media (min-width:1024px), turn main into flex:
    • Sidebar: fixed 300 px width, sticky below navbar
    • .main-content: flex:1 to occupy remaining space
    • Navbar: absolutely positioned at top-right of content
  • Switched justify-content to flex-start so sidebar stays flush left
• Kept all existing CSS rules intact, only reorganized under /* BASE */, /* LAYOUT */, etc.
• Adjusted breakpoints for consistency (1024px layout, 1250px scrollbar tweaks)

Checklist

• CSS partials imported correctly in HTML (or via @import in a single entry file)
• Manual tests pass on desktop (>=1024px) and mobile (<1024px)
• No visual regressions in existing sections

Code Review: Responsive Two-Column Layout & CSS Refactor

What’s working well 👏

• Splitting CSS into partials (base.css, layout.css, components.css, utilities.css) greatly improves maintainability.
• Using flex + media queries at 1024px matches the intended design.
• All original styles are preserved with no duplicates or omissions.

Suggestions for improvement 💡

• Rename .main-content to a more semantic class (e.g. .content-wrapper) to avoid confusion.
• Extract the sidebar’s fixed width (300px) into a CSS variable in base.css for easier future adjustments.
• Add a comment above the breakpoint, for example:

  /* Two-column layout from 1024px up */
