T3BS3 Template: How to add a background image to part of the frontpage

Hi everyone,

Using the great new T3BS3 template, I would like to add a background image to the part of the frontpage that (in the demo) says: “Welcome to T3 The all new, modern and flexible framework from JoomlArt.”. So the image should NOT cover the whole background. It should only fill the width of the page on that part or box on the frontpage.

I’ve tried re-defining the jumbotron masthead class in a custom.css file (with the line “background-image: url(‘myimage.jpg’);” in it), but this has no effect.

I am not sure how to do this. Any help would be much appreciated!
