Use media queries… don't use media queries… whatever. Cycle2 doesn't care ; it's the honeybadger of slideshows plugins. Most of the demos on this site use fluid slideshow designs where the slideshow size adjusts as the window is resized. This is accompolished by a simple style rule like this : .cycle-slideshow width : 45% . Your slideshows can be fixed-width or fluid-width, or they can adapt to media query breakpoints. You decide !
