## Description
|
|||
|
<section id="description">在HTML元素上应用颜色不仅限于一个平面色调。 CSS提供了在元素上使用颜色过渡(也称为渐变)的功能。这可以通过<code>background</code>属性的<code>linear-gradient()</code>函数访问。这是一般语法: <code>background: linear-gradient(gradient_direction, color 1, color 2, color 3, ...);</code>第一个参数指定颜色过渡开始的方向 - 它可以表示为度,其中90deg为垂直渐变,45deg的角度为反斜杠。以下参数指定渐变中使用的颜色顺序。示例: <code>background: linear-gradient(90deg, red, yellow, rgb(204, 204, 255));</code> </section>

|
|||
|
## Instructions
|
|||
|
<section id="instructions">对<code>div</code>元素的<code>background</code>使用<code>linear-gradient()</code> ,并从35度的方向设置它以将颜色从<code>#CCFFFF</code>更改为<code>#FFCCCC</code> 。 <strong>注意</strong> <br>虽然还有其他方法可以指定颜色值,例如<code>rgb()</code>或<code>hsl()</code> ,但请为此挑战使用十六进制值。 </section>

testString: 'assert(code.match(/background:\s*?linear-gradient\(35deg,\s*?(#CCFFFF|#CFF),\s*?(#FFCCCC|#FCC)\);/gi), "The <code>div</code> element should have a <code>linear-gradient</code> <code>background</code> with the specified direction and colors.");'
