Horizontal stack card size issue [Solved]

I added a horizontal stack card with three picture glances card and each one contains a feed from a camera.
While the cards are aligning perfectly, I wish if I could make the default larger than the current postage stamp!!

The documentation for Hosrizontal-stack card did not say anything about defining size so not sure if there is a fix available but would welcome comments if I missed some details.
Thanks.

The horizontal stack only fills a column width. Try panel mode (view options) and it should use the width of the screen.

Yes that did help increasing the size to let all three cards cover full width available!
Thanks.

I have the same issue, where can I find this view option >

Kind regard Frank

I think he’s talking about this part in red. I’m not really sure either. I’ve been looking for this panel view for the last hour.
