In general, I made a slider, it works normally (slick slider), I put the whole thing in tabs and when switching on them, it seems to be there (but it does not seem to be there). What is interesting, if you open the console on f12 - it appears. Who faced this? How to fix? 
$(document).ready(function () { $('.tab-content').hide(); $('.tab-content:first').show(); $('.tabs li:first').addClass('active'); $('.tabs li').click(function () { $('.tabs li').removeClass('active'); $(this).addClass('active'); $('.tab-content').hide(); var selectTab = $(this).find('a').attr("href"); $(selectTab).fadeIn(); return false; }); $('.sl').slick({ cssEase: 'ease-in', asNavFor: '.sl2', initialSlide: 1, autoplaySpeed: 2000, fade: true, infinite: false, draggable: true }); $('.sl2').slick({ slidesToShow: 5, slidesToScroll: 1, asNavFor: '.sl', focusOnSelect: true, arrows: false, infinite: false, draggable: true, accessibility: false }); $('.sl3').slick({ arrows: true }); });
