Creating a slider that slides items in an arc / upper cricle


I'm attempting to create a carousel that rotates items in a upper circle / arc fashion. This is how it's supposed to roll: https://thumbs.gfycat.com/HastyTemptingBarnswallow-mobile.mp4

My initial thought is to have 1 element in the middle then one previous and next which are slightly rotated. Upon dragging it should move all items along the x-axis and slightly rotate. This is my attempt:

Problem is I can't seem to make the dragging animation very smooth. I might also just be overthinking this and go in the wrong direction. Any advice?


Solution

  • I used the following link to create an effect like the one you want

    https://tympanus.net/codrops/2013/08/09/building-a-circular-navigation-with-css-transforms/

    You will have to adjust the CSS according to your UI.

    $('.opened-nav li').click(function(event) {
      var index = $(".opened-nav li").index(this);
      console.log(index)
      if (index >= 7) {
        return;
      }
    
      let startDeg = 80;
      $('#cn-wrapper').css({
        '-webkit-transform': 'scale(2) rotate(' + (startDeg - (index) * 40) + 'deg)',
        '-moz-transform': 'scale(2) rotate(' + (startDeg - (index) * 40) + 'deg)',
        '-ms-transform': 'scale(2) rotate(' + (startDeg - (index) * 40) + 'deg)',
        '-o-transform': 'scale(2) rotate(' + (startDeg - (index) * 40) + 'deg)',
        'transform': 'scale(2) rotate(' + (startDeg - (index) * 40) + 'deg)'
      });
      /* console.log(event) */
    })
    @import url(http://netdna.bootstrapcdn.com/font-awesome/2.0/css/font-awesome.css);
