I have added a 960×300 image to the ‘before content’ widget and have since tried a few other image sizes but am getting white space around it, whereas we want it to fill all available space as it does on your Verbosa screenshots. I’m sure it is a simple setting/change but can you point me in the right direction?
The theme’s screenshot uses the new Landing Page feature (introduced in update 1.0.0) which features a static slider location (replaceable with an actual slider).
