+<p> <strong><code>background-repeat</code></strong> <a href="https://developer.mozilla.org/en-US/docs/CSS">CSS</a> 属性定义背景图像的重复方式。背景图像可以沿着水平轴,垂直轴,两个轴重复,或者根本不重复。</p>

+<p>默认情况下,重复的图像被剪裁为元素的大小,但它们可以缩放 (使用 <code>round</code>) 或者均匀地分布 (使用 <code>space</code>).</p>

+ <dd>单值语法是完整的双值语法的简写:</dd>
+ <dd>
+ <table>
+ <tbody>
+ <tr>
+ <td><strong>单值</strong></td>
+ <td><strong>等价于双值</strong></td>
+ </tr>
+ <tr>
+ <td><code>repeat-x</code></td>
+ <td><code>repeat no-repeat</code></td>
+ </tr>

+ <td><code>round round</code></td>
+ </tr>
+ <tr>
+ <td><code>no-repeat</code></td>
+ <td><code>no-repeat no-repeat</code></td>
+ </tr>
+ </tbody>
+ </table>
+ 在双值语法中, 第一个值表示水平重复行为, 第二个值表示垂直重复行为. 下面是关于每一个值是怎么工作的具体说明:</dd>
+ <dd>
+ <table class="standard-table">
+ <tbody>
+ <tr>
+ <td><code>repeat</code></td>
+ <td>
+ <p>图像会按需重复来覆盖整个背景图片所在的区域. 最后一个图像会被裁剪, 如果它的大小不合适的话.</p>
+ </td>
+ </tr>
+ <tr>
+ <td><code>space</code></td>
+ <td>
+ <p>图像会尽可能得重复, 但是不会裁剪. 第一个和最后一个图像会被固定在元素(element)的相应的边上, 同时空白会均匀地分布在图像之间. {{cssxref("background-position")}}属性会被忽视, 除非只有一个图像能被无裁剪地显示. 只在一种情况下裁剪会发生, 那就是图像太大了以至于没有足够的空间来完整显示一个图像.</p>
+ </td>
+ </tr>
+ <tr>
+ <td><code>round</code></td>
+ <td>
+ <p>随着允许的空间在尺寸上的增长, 被重复的图像将会伸展(没有空隙), 直到有足够的空间来添加一个图像. 当下一个图像被添加后, 所有的当前的图像会被压缩来腾出空间. 例如, 一个图像原始大小是260px, 重复三次之后, 可能会被伸展到300px, 直到另一个图像被加进来. 这样他们就可能被压缩到225px.</p>
+
+ <p>译者注: 关键是浏览器怎么计算什么时候应该添加一个图像进来, 而不是继续伸展.</p>
+ </td>
+ </tr>
+ <tr>
+ <td><code>no-repeat</code></td>
+ <td>
+ <p>图像不会被重复(因为背景图像所在的区域将可能没有完全被覆盖). 那个没有被重复的背景图像的位置是由{{cssxref("background-position")}}属性来决定.</p>
+ </td>
+ </tr>
