That’s hard to answer because what’s too hard for one person is easy for another. Please Google “css slider” and keep searching.
Hi, welcome to Sitepoint 
Yes that’s a difficult question to answer without more knowledge of what you are looking for and what you want to achieve. A CSS slider could mean many things so you will need to go into a little more detail or show us something that you have tried or something that you like.
Most sliders will need JS unless they are advanced CSS3 techniques and even then JS is still preferable to get the right behaviour. CSS tricks has an anything slider that is pretty useful.
