Walkthrough

The CSS file was updated to introduce new color variables for light and dark themes, targeting secondary backgrounds and active breadcrumb items. Additional styles were added for video containers, markdown content, and breadcrumb navigation, enhancing appearance and layout without altering or removing existing styles.

Changes

File Change Summary
src/css/custom.css Added new color variables, enhanced .video-container styling, and introduced new styles for markdown and breadcrumbs.

Poem

In fields of code where styles bloom bright,
New colors and breadcrumbs take their flight.
Videos framed with gentle grace,
Markdown lines with extra space.
A rabbit hops through CSS delight—
Scrollable trails and borders light,
All is styled just right!

109-111: Consider exploiting aspect-ratio & box-sizing for cleaner video wrapper

The classic padding-hack works, but most evergreen browsers now support the modern aspect-ratio property, which eliminates the need for magic padding and greatly simplifies maintenance.

 .video-container { @@ max-width: 100%; background: #000; + box-sizing: border-box; /* avoid accidental overflow with the new border */ + aspect-ratio: 16 / 9; /* modern, self-documenting replacement */ border-radius: 1rem; border: 4px solid var(--ifm-background-color-secondary); }

Keeps legacy behaviour while modern browsers pick the simpler path.


313-337: Hide-scrollbar helper only covers WebKit – add Firefox/legacy equivalents

::-webkit-scrollbar handles Chrome/Safari but leaves the scrollbar visible in Firefox/old Edge. A couple of compact properties plug the gap and keep UX consistent.

 .breadcrumbs { display: flex; gap: 0.5rem; overflow-x: auto; white-space: nowrap; + scrollbar-width: none; /* Firefox */ + -ms-overflow-style: none; /* old Edge/IE */ } .breadcrumbs::-webkit-scrollbar { display: none; }

Optionally, -webkit-overflow-scrolling: touch; can be added for smoother iOS momentum scrolling.

42-44: New CSS-custom-props look good

The additional theme-agnostic variables are well-named and scoped alongside existing palette tokens. Nice incremental extension.


56-58: Dark-theme counterparts correctly mirror the light-theme tokens

Parity between light and dark palettes is preserved—good attention to detail.


307-310: Typography tweak is harmless

Bumping default line-height improves readability without side-effects. 👍

What's the motivation for adding capsule background to the breadcrumbs? I have a concern that they look more like buttons or active links now, but none of them are actually links, other than the leftmost "Home" icon.

What's the motivation for adding capsule background to the breadcrumbs? I have a concern that they look more like buttons or active links now, but none of them are actually links, other than the leftmost "Home" icon.

  • The capsule design is intended to maintain visual consistency within the breadcrumb elements.
  • Without this design treatment, the breadcrumb text would blend in with the rest of the page content, reducing clarity and hierarchy.
  • While breadcrumbs are typically clickable for navigation, in our case they do not redirect anywhere.
  • The design choice helps differentiate these static breadcrumbs from other text elements, preserving their intended role as contextual indicators.
