UBB.threads PHP Forum Software Community Forums UBB.threads Bug Reports table.t_outer causes 0.12 CLS on forum listing pages

Summary:

The same #body_col > table.t_outer element causes a layout shift on forum listing pages when the table body renders at 0px height before expanding.

Environment:

URL: https://www.stovebolt.com/ubbthreads/ubbthreads.php/forums/65/1/project-journals
Affected element: #body_col > table.t_outer
CLS impact: P50–P99 = 0.12

Observed behavior:

Initial render: { width: 0, height: 0 }
Post-load: { width: 0, height: 588 }
The outer table container has no intrinsic or reserved height before the forum listing rows are populated, causing a downward shift of ~588px.

Expected behavior:

The outer table should reserve vertical space for the forum listing content before paint.

Suggested fix:

Apply a min-height CSS rule to #body_col > table.t_outer on forum listing templates, or render a placeholder row structure server-side so the table has non-zero height immediately.
