Problem with slideshow

[szczemat]

Hi!

Firstly i'm sorry for my english. I'm from Poland and i'm still learning :-).

 

I'm asking you for help. I nedd to build gallery like this: http://thecodeplayer.com/walkthrough/css3-image-slider-with-stylized-thumbnails (it's free to use).

 

Slide will be placed in one of cms pages.

I edited CSS file and add necessary code in cms editor. Slider is on, but i can't change photo.

 

I have extended-rich-text-editor in presta shop and nothing is changed.

 

Any ideas what went wrong? I will appreciate any help. Big THX!
