Slideshow not displaying properly on smartphone

sorry, my brain is still in holidays

check in your file, the code is still there
www.batcsoftball.nl/templates/batc_templ...plate.responsive.css

may be that your css file is generated automatically each time you load the page ? or a cache problem

use a custom css and add this

Thank you for your help. I added the code you suggested and cleared the cache on my phone. The slide show is now centering properly! Many thanks!
