Featured slider is not responsible

The feature slider is a neat content display, but unfortunately is does not work on mobile devices! It is not responsible as the font size is not adjusted. And the header area with the site logo is shown ave the featured slider like on pc layouts. You can check it out at: http://mr-mojo-risin.net a) Will there be a fix for the font size issue? b) Is there a possiblity to set the header with the main menu on fixed or block so the featured slider will scroll or disappear below the site logo and the main navigation (like it does on all the subpages)?
