How to Reduce Banner Image Width(branding) in Knowledge Portal (Service Portal)

FemyM · ‎04-16-2025

Hi Community,

I'm trying to reduce the width of the banner image in the Knowledge Portal (built on Service Portal). When I inspect the element, I see a banner-container.
How can i reduce the width of banner image.

Hi @FemyM

I tried changing the configuration via the portal, but it didn’t work. The point is, this is a standard image used across platforms, and we can only make size changes for one portal. I believe this image is stored in the db_image table. You need to download this image and change size and then upload but it wil be global change.

Even if I use another image with different dimension, the banner width is not reduced
