Warning::
https://hessen.de/sites/hessen.hessen.de/files/hes... is missing width/height — may cause layout shift
Set explicit width and height to prevent CLS.
7 images 441 KB
0 oversized -0 KB
7 legacy format
1 missing dimensions CLS risk

Set explicit width and height to prevent CLS.

Why this matters

Image without explicit width/height — browser can't reserve space; CLS jumps when image loads.
