## Description
|
|||
|
<section id="description">许多人对超过1600万种颜色的可能性感到不知所措。并且很难记住十六进制代码。幸运的是,你可以缩短它。例如,红色的十六进制代码<code>#FF0000</code>可以缩短为<code>#F00</code> 。这个缩短的形式给出一个红色数字,一个数字表示绿色,一个数字表示蓝色。这将可能的颜色总数减少到大约4,000。但浏览器会将<code>#FF0000</code>和<code>#F00</code>解释为完全相同的颜色。 </section>

|
## Instructions
|
|||
|
<section id="instructions">继续,尝试使用缩写的十六进制代码为正确的元素着色。 <table class="table table-striped"><tbody><tr><th>颜色</th><th>短十六进制代码</th></tr><tr><td>青色</td><td> <code>#0FF</code> </td> </tr><tr><td>绿色</td><td> <code>#0F0</code> </td> </tr><tr><td>红</td><td> <code>#F00</code> </td> </tr><tr><td>紫红色</td><td> <code>#F0F</code> </td> </tr></tbody></table></section>
