I would like to use a content search webpart slideshow mode as the banner across the top of my share point page. When I add in the webpart, it is aligned to the left and only half of the size of the webpart container. I have not been able to reconfigure the size of the WebPart. Any hints?
I have managed to change the size of the slide show by following the guide in this link
This person explains how to modify the internal template (so it is not done using CSS on top of the page).
Further documentation (but not on the slideshow)
