HTML Structure

This mobile phone APP switches the HTML structure of image effects using nesting

Every picture card is enclosed in p. demo _ card, which contains pictures, descriptions, and some additional layers.

M -- reject is the layer for moving the image to the left, m -- like is the layer for moving the image to the right, and demo _ card _ drag is the drag layer.

JavaScript

In jQuery code, the pullChange () function is used to set the Rotation Angle and transparency of the left and right sliding layers. The release () function is used to determine whether the user slides his finger left or right and adds the corresponding class to the DOM element for these actions.

function pullChange() { animating = true; deg = pullDeltaX / 10; $card.css('transform', 'translateX(' + pullDeltaX + 'px) rotate(' + deg + 'deg)'); var opacity = pullDeltaX / 100; var rejectOpacity = opacity >= 0 ? 0 : Math.abs(opacity); var likeOpacity = opacity <= 0 ? 0 : opacity; $cardReject.css('opacity', rejectOpacity); $cardLike.css('opacity', likeOpacity);};function release() { if (pullDeltaX >= decisionVal) {  $card.addClass('to-right'); } else if (pullDeltaX <= -decisionVal) {  $card.addClass('to-left'); } if (Math.abs(pullDeltaX) >= decisionVal) {  $card.addClass('inactive');  setTimeout(function () {   $card.addClass('below').removeClass('inactive to-left to-right');   cardsCounter++;   if (cardsCounter === numOfCards) {    cardsCounter = 0;    $('.demo__card').removeClass('below');   }  }, 300); } if (Math.abs(pullDeltaX) < decisionVal) {  $card.addClass('reset'); } setTimeout(function () {  $card.attr('style', '').removeClass('reset').find('.demo__card__choice').attr('style', '');  pullDeltaX = 0;  animating = false; }, 300);}; 

Finally, listen to the mousedown and touchstart events, and perform Card Switching for non-. inactive card elements.
