中心比例动画css3

Question

如何将中心应用于此比例动画？
正如您在下一个示例中看到的那样，div消失在右侧，我需要将中心应用于缩放动画：

＆＃13;

＆＃13;

$(document).ready(function() {
    $("button").click(function() {
        $(".container:first").addClass("remove")
    });
});

＆＃13;

.container {
  width: 200px;
  height: 260px;
  position: relative;
  margin: 0 auto 40px;
  -webkit-perspective: 800px;
  -moz-perspective: 800px;
  -o-perspective: 800px;
  perspective: 800px;
  display: inline-block;
}

#main {
  border: 1px solid black;
}

.card {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transition: -webkit-transform 1s;
  -moz-transition: -moz-transform 1s;
  -o-transition: -o-transform 1s;
  transition: transform 1s;
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  -o-transform-style: preserve-3d;
  transform-style: preserve-3d;
  -webkit-transform-origin: right center;
  -moz-transform-origin: right center;
  -o-transform-origin: right center;
  transform-origin: right center;
}

.card.flipped {
  -webkit-transform: translateX( -100%) rotateY( -180deg);
  -moz-transform: translateX( -100%) rotateY( -180deg);
  -o-transform: translateX( -100%) rotateY( -180deg);
  transform: translateX( -100%) rotateY( -180deg);
}

.card div {
  height: 100%;
  width: 100%;
  color: white;
  text-align: center;
  font-weight: bold;
  position: absolute;
  -webkit-backface-visibility: hidden;
  -moz-backface-visibility: hidden;
  -o-backface-visibility: hidden;
  backface-visibility: hidden;
  cursor: pointer;
}

.card .front {
  background: red;
  display: flex;
  justify-content: center;
  align-items: center;
}

.card .back p {
  margin: auto;
}

.card .back {
  background: blue;
  -webkit-transform: rotateY( 180deg);
  -moz-transform: rotateY( 180deg);
  -o-transform: rotateY( 180deg);
  transform: rotateY( 180deg);
  display: flex;
  justify-content: center;
  align-items: center;
}
.remove{
    -webkit-transition: -webkit-transform 1s;
    -moz-transition: -moz-transform 1s;
    -o-transition: -o-transform 1s;
    transition: transform 1s;
    -webkit-transform-style: preserve-3d;
    -moz-transform-style: preserve-3d;
    -o-transform-style: preserve-3d;
    transform-style: preserve-3d;
    -webkit-transform-origin: right center;
    -moz-transform-origin: right center;
    -o-transform-origin: right center;
    transform-origin: right center;
    animation: removeAnim 0.5s ease,
    otherAnimation 0.5s ease;
}
@keyframes otherAnimation {
    0%   {
        transform: scale(1.0);
    }
    25%  {
        transform: scale(0.75);
    }
    50%  {
        transform: scale(0.50);
    }
    75%  {
        transform: scale(0.25);
    }
    100%{
        transform: scale(0);
    }
}

Answer 1

将CSS中的.remove类编辑为：

transform-origin: center;

或者只删除此类中对transform-origin的所有引用，因为默认为中心。

$(document).ready(function() {
    $("button").click(function() {
        $(".container:first").addClass("remove")
    });
});

.container {
  width: 200px;
  height: 260px;
  position: relative;
  margin: 0 auto 40px;
  -webkit-perspective: 800px;
  -moz-perspective: 800px;
  -o-perspective: 800px;
  perspective: 800px;
  display: inline-block;
}

#main {
  border: 1px solid black;
}

.card {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transition: -webkit-transform 1s;
  -moz-transition: -moz-transform 1s;
  -o-transition: -o-transform 1s;
  transition: transform 1s;
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  -o-transform-style: preserve-3d;
  transform-style: preserve-3d;
  -webkit-transform-origin: right center;
  -moz-transform-origin: right center;
  -o-transform-origin: right center;
  transform-origin: right center;
}

.card.flipped {
  -webkit-transform: translateX( -100%) rotateY( -180deg);
  -moz-transform: translateX( -100%) rotateY( -180deg);
  -o-transform: translateX( -100%) rotateY( -180deg);
  transform: translateX( -100%) rotateY( -180deg);
}

.card div {
  height: 100%;
  width: 100%;
  color: white;
  text-align: center;
  font-weight: bold;
  position: absolute;
  -webkit-backface-visibility: hidden;
  -moz-backface-visibility: hidden;
  -o-backface-visibility: hidden;
  backface-visibility: hidden;
  cursor: pointer;
}

.card .front {
  background: red;
  display: flex;
  justify-content: center;
  align-items: center;
}

.card .back p {
  margin: auto;
}

.card .back {
  background: blue;
  -webkit-transform: rotateY( 180deg);
  -moz-transform: rotateY( 180deg);
  -o-transform: rotateY( 180deg);
  transform: rotateY( 180deg);
  display: flex;
  justify-content: center;
  align-items: center;
}
.remove{
    -webkit-transition: -webkit-transform 1s;
    -moz-transition: -moz-transform 1s;
    -o-transition: -o-transform 1s;
    transition: transform 1s;
    -webkit-transform-style: preserve-3d;
    -moz-transform-style: preserve-3d;
    -o-transform-style: preserve-3d;
    transform-style: preserve-3d;
    -webkit-transform-origin: center;
    -moz-transform-origin: center;
    -o-transform-origin: center;
    transform-origin: center;
    animation: removeAnim 0.5s ease,
    otherAnimation 0.5s ease;
}
@keyframes otherAnimation {
    0%   {
        transform: scale(1.0);
    }
    25%  {
        transform: scale(0.75);
    }
    50%  {
        transform: scale(0.50);
    }
    75%  {
        transform: scale(0.25);
    }
    100%{
        transform: scale(0);
    }
}

</div>

Answer 2

从CSS中的.remove类中删除以下行。

-webkit-transform-origin: right center;
-moz-transform-origin: right center;
-o-transform-origin: right center;
transform-origin: right center;

Answer 3

您在 .remove 类中指定了transform-origin: right center：

.remove{
    -webkit-transition: -webkit-transform 1s;
    -moz-transition: -moz-transform 1s;
    -o-transition: -o-transform 1s;
    transition: transform 1s;
    -webkit-transform-style: preserve-3d;
    -moz-transform-style: preserve-3d;
    -o-transform-style: preserve-3d;
    transform-style: preserve-3d;
    -webkit-transform-origin: right center;  // Remove this line
    -moz-transform-origin: right center;     // Remove this line
    -o-transform-origin: right center;       // Remove this line
    transform-origin: right center;          // Remove this line
    animation: removeAnim 0.5s ease,
    otherAnimation 0.5s ease;
}

您可以删除这些行，因为center center是默认行为
