Sizing cards/widgets

Hi everybody, thanks very much for your help to date, I'm flying along now making my own dashboard nodes for various sensors using the template.

The problem I'm encountering now is how to control the layout/sizing of each node on the dashboard.

As far as I understand it, if you choose 'auto' for the size of the node, then it looks at the html styling in the template for its size. However, say I have 3 nodes on my dashboard in a line horizontally if I specify a height and width of 200px for one of them, it changes all the nodes to that size, not just the one.

I'm guessing this is so they all fit into a grid, but is there any way to get more control over this.

Kind regards

Paul
