Problem
Thumbnail split-screen dividers consume too much width and shrink both subjects below readable scale.
Solution
Root Cause / Diagnostic:
Overly thick decorative borders, lightning bolts, or gradient separator bars consume valuable canvas real estate. This compresses the active image areas on either side, forcing subjects into squashed aspect ratios that fail to resolve on mobile viewports.
Actionable Fix:
1. Reduce split-screen divider thickness to a razor-thin 2 px to 6 px line, or replace solid borders with a clean 1 px white stroke featuring a subtle drop shadow (distance 3, spread 0, size 8).
2. Maximize horizontal area by allocating at least 48% canvas width to each comparative half.
3. Verify that main subjects occupy at least 80% vertical height within their respective halves at mobile preview dimensions.
Pro Tip:
A clean 2 px stroke with high contrast cuts the canvas cleanly without stealing pixel territory from your narrative subjects.
