Responsive layout positioning

I have created a page with a slider and text below. http://swoonline.co.uk/wordpress/

So the text sits immediately beneath the slider. Or at least it should. On the desktop version of the site this is exactly what happens, however, when the page reconfigures for an Android smartphone there is an unacceptable vertical gap between the slider and the text. I suspect the solution lies in a css file, but have not located this as yet. Does anyone know how to control this? Thanks.
