the "sliker__item--selected" class is optionnal. Without it, the slider will simply start at the first sliker__item

"sliker--safeload" is an option that preserve the aspect of the slider before the initialization of the javascript (window load here). In this example, the call is commented out to show the slider style in this short period of time before loading.

Bullets and arrows are customs. The options are in the data-properties on the root of the slider

With the "liquid" option at 0, the sliker__items don't thake the full with. So, we need to set their width in css to see them.
IMPORTANT: a sliker without liquid should NOT use the "sliker--safeload" option.
