问题:

I'm trying to re-create the bouncing arrow animation like on: http://www.codecomputerlove.com/ but it's not going well...

The closest I've got with trying to use the built in animations in Layerslider is available here: dev.themarketcreative dot com

I've decided that trying to figure this out with Layerslider is taking to long, does anyone know how to do this?

The furthest I discovered is this: http://www.tutorialspoint.com/cgi-bin/practice.cgi?file=jquery_149 but I need it do do this animation onload and on a continuous loop.

Thanks

PURE CSS way to do this bounce

Do like this.

.bounce {
      position:fixed;
      left:50%;
      bottom:0;
      margin-top:-25px;
      margin-left:-25px;
      height:50px;
      width:50px;
      background:red;
      -webkit-animation:bounce 1s infinite;
    }
    
    @-webkit-keyframes bounce {
      0%       { bottom:5px; }
      25%, 75% { bottom:15px; }
      50%      { bottom:20px; }
      100%     {bottom:0;}
    }

<div class="bounce"></div>

You can do it manually, frame-by-frame using CSS or you can probably automate it with SCSS with a bit of math and iteration.

body{ overflow:hidden; } 

.ball{
	width: 50px;
	height: 50px;
	margin: auto;
	background-color: red;
	border-radius: 50%;
	position: absolute;
	top: 10px; 
	left: 0;
	right: 0;
	animation: bounce 1s infinite; 
}

@keyframes bounce {
    0%   { transform: translateY(6px); }
    5%   { transform: translateY(8px); }
    10%  { transform: translateY(12px); }
    15%  { transform: translateY(20px); }
    20%  { transform: translateY(38px); }
    25%  { transform: translateY(72px); }
    30%  { transform: translateY(100px); }
    35%  { transform: translateY(152px); }
    40%  { transform: translateY(154px) scale(1.1, .9); }
    50%  { transform: translateY(176px) scale(1.4, .6); }
    55%  { transform: translateY(162px) scale(1.2, .8); }
    60%  { transform: translateY(138px) scale(1.05, .95); }
    65%  { transform: translateY(110px); }
    70%  { transform: translateY(72px); }
    75%  { transform: translateY(38px); }
    80%  { transform: translateY(20px); }
    85%  { transform: translateY(12px); }
    90%  { transform: translateY(8px); }
    95%  { transform: translateY(5px); }
    100% { transform: translateY(5px); }
}

<div class="ball"></div>

Use following

<html lang="en">
<head>
 <style>
      p {
           background-color:#bca;
           width:200px; 
           border:1px solid green; 
        }
     div{ width:100px; 
            height:100px; 
            background:red;  
        }
  </style>

<script src="http://www.tutorialspoint.com/jquery/jquery-1.3.2.min.js"></script> 
<script src="http://www.tutorialspoint.com/jquery/jquery-ui-1.7.2.custom.min.js"></script>

<title>Birman Cats</title>
</head>

<body>

   <p>Click the button</p>
   <button id="button"> Bounce </button>

   <div class="target">
   </div>

<script>

   $(document).ready(function() {


         $(".target").effect( "bounce", 
          {times:3}, 300 );

         function bouncee(){

                $(".target").effect( "bounce",{times:3}, 300 );
   setTimeout(bouncee(),1000);
             }

     setTimeout(bouncee(),1000);


   });

</script>
</body>
</html>

回答5:

With the same code you provided, just replace the javascript with this js code.

    $(document).ready(function() {



      function doAnimation()
{
         $(".target").effect( "bounce", {times:3}, 300, doAnimation);
}

doAnimation();

   });
   </script>

回答6:

You can use pure css to solve it Simple one.

<div class="image"></div>

.image {
  margin-top: 50px;
  width: 50px;
  height: 50px;
  background-color: gold;
  border: 1px solid #999;
  animation: bounce 5s infinite alternate;
  -webkit-animation: bounce 5s infinite alternate;
}
@keyframes bounce {
  from {
    transform: translateY(0px);
  }
  to {
    transform: translateY(-55px);
  }
}
@-webkit-keyframes image {
  from {
    transform: translateY(0px);
  }
  to {
    transform: translateY(-55px);
  }
}
