<strong>指定动画名称和动画效果。</strong>
<ul>
<li><a href="@keyframes.htm">@keyframes</a>定义的动画名称用来被<a href="../properties/animation/animation-name.htm">animation-name</a>所使用。</li>
<li>
<strong>定义动画时，简单的动画可以直接使用关键字from和to，即从一种状态过渡到另一种状态：</strong>
<div class="gquote">
<p class="gquote-tit"><strong>示例代码：</strong></p>
<blockquote class="gquote-cont"><code><xmp>@keyframes testanimations {
from { opacity: 1; }
to { opacity: 0; }
}</xmp></code></blockquote>
<p class="gquote-info">其中testanimations是该动画的名字，该动画表示某个东西将逐渐消失。</p>
</div>
</li>
<li>
<strong>如果复杂的动画，可以混合<a href="../values/numeric/percentage.htm"><percentage></a>去设置某个时间段内的任意时间点的样式：</strong>
<div class="gquote">
<p class="gquote-tit"><strong>示例代码：</strong></p>
<blockquote class="gquote-cont"><code><xmp>@keyframes testanimations {
from { transform: translate(0, 0); }
20% { transform: translate(20px, 20px); }
40% { transform: translate(40px, 0); }
60% { transform: translate(60px, 20); }
80% { transform: translate(80px, 0); }
to { transform: translate(100px, 20px); }
}</xmp></code></blockquote>
</div>
</li>
<li>
<strong>当然，也可以不使用关键字from和to，而都使用<a href="../values/numeric/percentage.htm"><percentage></a>：</strong>
<div class="gquote">
<p class="gquote-tit"><strong>示例代码：</strong></p>
<blockquote class="gquote-cont"><code><xmp>@keyframes testanimations{
0% { transform: translate(0, 0); }
20% { transform: translate(20px, 20px); }
40% { transform: translate(40px, 0); }
60% { transform: translate(60px, 20px); }
80% { transform: translate(80px, 0); }
100% { transform: translate(100px, 20px); }
}</xmp></code></blockquote>
<p class="gquote-info">注意，这里的0%不能简写成0，0是非标准语法（虽然被某些浏览器所支持）。</p>
