Mobile Warning: Code Block Horizontal Overflow
All 4 mobile viewports (360–428px wide) show a code block overflow issue on the landing page:
- The Expressive Code YAML workflow example block contains lines whose rendered width reaches ~554px (
white-space: pre) body.scrollWidth(554px) exceedsbody.clientWidth(344–412px) on all mobile viewportsbody, html { overflow-x: hidden }clips the overflow — no horizontal scrollbar appears, so mobile users cannot scroll to see truncated content- The
<pre>element hasoverflow-x: autovia EC CSS, but the body-level hidden overflow suppresses this at narrow viewports - Breakpoint: overflow resolves at ~600px viewport width (550px overflows, 600px does not)

Recommendations
- Fix mobile code block overflow — The landing page YAML example is clipped on all mobile viewports < ~560px. Options:
- Add
overflow-x: auto(nothidden) on the code block's container at mobile breakpoints, or - Shorten the longest YAML lines in the example to fit within ~360px rendered width, or
- Add a media query to allow horizontal scroll within the code block wrapper while keeping page-level overflow hidden
- Add
