Why does the slick-slider sometimes collapse?

Question

css

Hello everyone
Site
Sometimes, and it is impossible to track the pattern, the slick collapses. Initialization passes, pictures are loaded, but at the output I get a narrow strip of a couple of pixels. After refreshing the page, everything falls into place
. What could be the problem?

Answer 1

Maybe the pictures are not loaded before the slick is initialized?

Answer 2

Do you reload when you make changes? Maybe something is being cached?
Sergei is correct. Initialize slider in

$(document).ready( function(){
 ...
})
