I absolutely love image or text sliders written using pure css code. Likewise, i always hated slow loading sliders using jquery or javascript to use in my wordpress themes or html websites. I have compiled some cool css sliders from codepen/github for use in your website or in themes, many are responsive too :)). A word of advise: Please make sure to test all sliders in Safari, Chrome and FF before deployment.
