Question

我试图让这个按钮与CSS3反弹

＆＃13;

.order {
  position: absolute;
  top: 50px;
  left: 50px;
  width: 75px;
  line-height: 75px;
  text-align:center;
  opacity: 1;
  background: green;
  color:#fff;
  border-radius:50%;
}

＆＃13;

<div class="order">Order</div>

＆＃13;

我希望它能够在屏幕上（在Z轴上）向上和向下反弹。

Answer 1

您可以使用关键帧动画来设置按钮缩放比例的动画并使其反弹：

＆＃13;

.order {
  position: absolute;
  top: 50px;
  left: 50px;
  width: 75px;
  line-height: 75px;
  text-align:center;
  opacity: 1;
  background: green;
  color:#fff;
  border-radius:50%;
  -webkit-animation: bounce .3s infinite alternate;
  -moz-animation: bounce .3s infinite alternate;
  animation: bounce .3s infinite alternate;
}
@-webkit-keyframes bounce {
  to { -webkit-transform: scale(1.2); }
}
@-moz-keyframes bounce {
  to { -moz-transform: scale(1.2); }
}
@keyframes bounce {
  to { transform: scale(1.2); }
}

＆＃13;

<div class="order">Order</div>

＆＃13;

迭代次数：

如果你想在一些＆＃34;反弹＆＃34;之后停止动画，你可以使用animation-iteration-count（使用偶数次迭代，否则动画将在结尾处捕捉）：

＆＃13;

.order {
  position: absolute;
  top: 50px;
  left: 50px;
  width: 75px;
  line-height: 75px;
  text-align:center;
  opacity: 1;
  background: green;
  color:#fff;
  border-radius:50%;
  -webkit-animation: bounce .3s infinite alternate;
  -moz-animation: bounce .3s infinite alternate;
  animation: bounce .3s infinite alternate;
  -webkit-animation-iteration-count: 8;
  -moz-animation-iteration-count: 8;
  animation-iteration-count: 8;
}
@-webkit-keyframes bounce {
  to { -webkit-transform: scale(1.2); }
}
@-moz-keyframes bounce {
  to { -moz-transform: scale(1.2); }
}
@keyframes bounce {
  to { transform: scale(1.2); }
}

＆＃13;

<div class="order">Order</div>

＆＃13;

Answer 2

web-tiki发布的答案是最好用的，我仍然采用不同的方法becoz你已经使用position:absolute。

见FIDDLE 你需要使用关键帧为按钮设置高度和宽度的动画。

＆＃13;

.order {
  background: url("http://onestudio.id-staging.com/_BUILD/Dominos/BANNERS/C3%20Digital%20Midweek%20Rescue/Wide%20Skyscraper/images/order.png") no-repeat;
  position: absolute;
  background-size: cover;
  top: 50px;
  left: 50px;
  width: 75px;
  height: 75px;
  z-index: 1;
  opacity: 1;
  -webkit-animation: mymove 1s infinite;
  /* Chrome, Safari, Opera */
  animation: mymove 1s infinite;
}
/* Chrome, Safari, Opera */

@-webkit-keyframes mymove {
  0% {
    height: 75px;
    width: 75px;
  }
  50% {
    height: 100px;
    width: 100px;
  }
  100% {
    height: 75px;
    width: 75px;
  }
}
/* Standard syntax */

@keyframes mymove {
  0% {
    height: 75px;
    width: 75px;
  }
  50% {
    height: 100px;
    width: 100px;
  }
  100% {
    height: 75px;
    width: 75px;
  }
}

＆＃13;

<div class="order"></div>

＆＃13;

修改

要进一步添加，您还可以将left和top设置为38px，以便将其设置为按钮看起来不像原来的位置看到这个 Fiddle

＆＃13;
＆＃13;
.order { background: url("http://onestudio.id-staging.com/_BUILD/Dominos/BANNERS/C3%20Digital%20Midweek%20Rescue/Wide%20Skyscraper/images/order.png") no-repeat; position: absolute; background-size: cover; top: 50px; left: 50px; width: 75px; height: 75px; z-index: 1; opacity: 1; -webkit-animation: mymove 1s infinite; /* Chrome, Safari, Opera */ animation: mymove 0.5s 2; } /* Standard syntax */ @keyframes mymove { 0% { height: 75px; width: 75px; left: 50px; top: 50px; } 50% { height: 100px; width: 100px; left: 38px; top: 38px; } 100% { height: 75px; width: 75px; left: 50px; top: 50px; } }
＆＃13;
<div class="order"></div>

Answer 3

试试这个css

.order {
    background:url("http://onestudio.id-staging.com/_BUILD/Dominos/BANNERS/C3%20Digital%20Midweek%20Rescue/Wide%20Skyscraper/images/order.png");
      background-size: cover;
      position: absolute;
      top:50px;
      left:50px;
      width: 75px;
      height: 75px;
      z-index:1;
      opacity:1;

}

@keyframes fade {
    from { top:40px;
      left:40px;
      width: 100px;
      height: 100px; }
    50% { top:50px;
      left:50px;
      width: 75px;
      height: 75px; }
    to { top:40px;
      left:40px;
      width: 100px;
      height: 100px; }
}

@-webkit-keyframes fade {
    from { top:40px;
      left:40px;
      width: 100px;
      height: 100px; }
    50% { top:50px;
      left:50px;
      width: 75px;
      height: 75px; }
    to { top:40px;
      left:40px;
      width: 100px;
      height: 100px; }
}

.blink {
    animation:fade 1000ms infinite;
    -webkit-animation:fade 1000ms infinite;
}

试试这个html

<div class="order blink"></div>

Answer 4

您可以像以下一样制作动画（反弹）：

<强> CSS：

.order {
    background:url("http://onestudio.id-staging.com/_BUILD/Dominos/BANNERS/C3%20Digital%20Midweek%20Rescue/Wide%20Skyscraper/images/order.png");
      position: absolute;
      top:50px;
      left:50px;
      width: 75px;
      height: 75px;
      z-index:1;
      opacity:1;
      animation: myfirst 2s infinite;
      -webkit-animation: myfirst 2s infinite; 
}

    @-webkit-@keyframes myfirst {

    0% {
    transform: scale(1);
  }
  50% {
   transform: scale(1.5);
  }
  100% {
   transform: scale(1);
  }
}

@keyframes myfirst {

    0% {
    transform: scale(1);
  }
  50% {
   transform: scale(1.5);
  }
  100% {
   transform: scale(1);
  }
}
