恒定的动画速度CSS [英] constant animation speed CSS

问题描述

我有一个动画，我想让动画在所有过渡上都做同样的动作，在我动画开始的很快，而几乎在结尾开始变慢.

i have an animation and i want to make the animation do the same move on all the transition, on what i have the animation begin fast and almost on the end begins to slow down.

#tableNews {
    overflow: hidden;
    margin-right: 5%;
    width:90%;
    position: relative;
    -webkit-animation: mymove 15s infinite; /* Chrome, Safari, Opera */
    animation: mymove 15s infinite;
}    
    /* Chrome, Safari, Opera */
@-webkit-keyframes mymove {
    from {top: 60px;}
    to {top: -200px;}
}

@keyframes mymove {
    from {top: 60px;}
    to {top: -200px;}
}

<table id="tableNews" class="TableList" border="0" width="100%" style="overflow:hidden;">
<tbody>                                                      
  <tr class="new-separator">                                                            
    <td>
      <table>
        <tr>
          <td><a href="#"></a><hr></td>
        </tr>
                                                                   
      </table>
    </td>
  </tr>
</tbody>
</table>

推荐答案

我想它正在使 ease 变得容易.如果您提供选项 linear ，即动画的

I guess it is making an ease. If you give an option linear, which is the animation's timing function, that works with constant speed and no delay. Let's do this way:

#tableNews {
    overflow: hidden;
    margin-right: 5%;
    width:90%;
    position: relative;
    -webkit-animation: mymove 15s linear infinite; /* Chrome, Safari, Opera */
    animation: mymove 15s linear infinite;
}    
    /* Chrome, Safari, Opera */
@-webkit-keyframes mymove {
    from {top: 60px;}
    to {top: -200px;}
}

@keyframes mymove {
    from {top: 60px;}
    to {top: -200px;}
}

<div id="tableNews">Hi</div>
