Hi all,
I have a web page that contains an entity list. I have a custom theme.css file applied to it via its parent page. I can adjust the height of containers within the page but am struggling to work out how to adjust the height of the form / entity list.
So, using chrome dev tools i can see as below that the form 'content_form' is 439.6px high.

Via the elements tab i can see this is set here:

And looking at the styles it seems it is using the user agent stylesheet for the form.

in not sure what I need to add to theme.css to stop this being used. I'm new to CSS and have tried .form{height:800px} but this made no difference.
Any advice appreciated.
Thanks
