+
+<p>CSS <strong>图像合并</strong>（<strong>Image sprites</strong>） 技术，亦作 CSS 贴图定位、图像精灵（sprite，意为精灵），被运用于众多使用大量小图标的网页应用之上。它可取图像的一部分来使用，使得使用一个图像文件替代多个小文件成为可能。相较于一个小图标一个图像文件，单独一张图片所需的 HTTP 请求更少，对内存和带宽更加友好。</p>
+
+<div class="note">
+<p>备注: 当使用 HTTP/2 时，使用多个小流量请求实际上可能更为带宽友好。</p>
+</div>
+
+<h2 id="实现">实现</h2>
+
+<p>若要为所有类名为 <code>toolbtn</code> 的元素附加上一张图片：</p>
+
+<pre class="brush:css">.toolbtn {
+  background: url(myfile.png);
+  display: inline-block;
+  height: 20px;
+  width: 20px;
+}
+</pre>
+
+<p>为设置 <code>background-position</code> 以使每个按钮得到合并后图片中的正确部分，可以在 <code>background</code> 属性中的 {{cssxref("url()")}} 后添加 x, y 两个坐标值，或直接使用 {{cssxref("background-position")}} 属性。例如：</p>
+
+<pre class="brush:css">#btn1 {background-position: -20px 0px}
+#btn2 {background-position: -40px 0px}
+</pre>
+
+<p>这会将 ID 为 btn1 的元素的背景向左移 20px，ID 为 btn2 的元素的背景向左移40px（假设这两个元素都带有 <code>toolbtn</code> 这个类且应用了上面 <code>background</code> 属性中定义的图片背景）</p>
+
+<p>类似的，你也可以使用下面的代码添加悬停效果：</p>
+
+<pre class="brush:css">#btn:hover {
+  background-position: <var>&lt;pixels shifted right&gt;</var>px <var>&lt;pixels shifted down&gt;</var>px;

+title: 使用 CSS 渐变
+slug: Web/Guide/CSS/Using_CSS_gradients
+translation_of: Web/CSS/CSS_Images/Using_CSS_gradients
+---
+<div>{{CSSRef}}</div>
+
+<p><strong>CSS 渐变</strong> {{cssxref("&lt;image&gt;")}} 类型的一种特殊类型 {{cssxref("&lt;gradient&gt;")}} 表示，由两种或多种颜色之间的渐进过渡组成。您可以选择三种类型的渐变：线性 (由 {{cssxref("linear-gradient")}} 函数创建)，径向(由 {{cssxref("radial-gradient")}} 函数创建) 和圆锥 (由 {{cssxref("conic-gradient")}} 函数创建)。您还可以使用 {{cssxref("repeating-linear-gradient")}} 和 {{cssxref("repeating-radial-gradient")}} 函数创建重复渐变。</p>
+
+<p>渐变可以在任何使用 <code>&lt;image&gt;</code> 的地方使用，例如在背景中。 由于渐变是动态生成的，因此它们可以消除对传统用于实现类似效果的栅格图像文件的需求。 此外，由于渐变是由浏览器生成的，因此在放大时它们看起来比栅格图像更好，并且可以动态调整大小。</p>
+
+<p>我们将从线性渐变开始介绍，然后以线性渐变为例介绍所有渐变类型支持的功能，然后继续介绍径向渐变，圆锥渐变和重复渐变。</p>
+
+<h2 id="使用线性渐变">使用线性渐变</h2>

+
+<p>所有的CSS渐变类型都是一个位置依赖的颜色范围。CSS渐变产生的颜色可以随位置不断变化，从而产生平滑的颜色过渡。也可以创建纯色带和两种颜色之间的硬过渡。以下内容适用于所有渐变函数：</p>

+<h3 id="颜色终止位置">颜色终止位置</h3>
+
+<p>你不需要让你设置的颜色在默认位置终止。 你可以通过给每个颜色设置0，1%或者2%或者其他的绝对数值来调整它们的位置。如果你将位置设置为百分数， <code>0%</code> 表示起始点, 而100%表示终点，但是如果需要的话你也可以设置这个范围之外的其他值来达到你想要的效果。如果有些位置你没有明确设置，那么它将会被自动计算，第一种颜色会在0%处停止，而最后一种颜色是100%，至于其他颜色则是在它邻近的两种颜色的中间停止。 </p>

+
+<p>要在两种颜色之间创建一条硬线，即创建一个条纹而不是逐渐过渡，可以将相邻的颜色停止设置为相同的位置。在此示例中，两种颜色在50%标记处共享一个颜色停止点，即渐变的一半：</p>

+<h3 id="渐变提示">渐变提示</h3>
+
+<p>默认情况下，渐变会平滑地从一种颜色过渡到另一种颜色。你可以通过设置一个值来将渐变的中心点移动到指定位置。 在如下示例中, 我们将渐变的中心点由50%设为10%。</p>

+<h3 id="创建色带和条纹">创建色带和条纹</h3>
+
+<p>要在渐变中包含一个实心的非过渡颜色区域，请包含颜色起止点的两个位置。颜色起止点可以有两个位置，这相当于两个连续颜色在不同位置具有相同的颜色起止点。颜色将在第一个颜色起止点时达到完全饱和，保持该饱和度到第二个颜色起止点，并通过相邻颜色起止点的第一个位置过渡到相邻颜色起止点的颜色。</p>

+      lime 25%, red 25% 50%, cyan 50% 75%, yellow 75% );
+}
+</pre>
+
+<p>{{ EmbedLiveSample('Creating_color_bands_stripes', 120, 120) }}</p>
+
+<p>In the first example above, the lime goes from the 0% mark, which is implied, to the 20% mark, transitions from lime to red over the next 10% of the width of the gradient, reach solid red at the 30% mark, and staying solid red up until 45% through the gradient, where it fades to cyan, being fully cyan for 15% of the gradient, and so on.</p>
+
+<p>In the second example, the second color stop for each color is at the same location as the first color stop for the adjacent color, creating a striped effect.</p>
+
+<p>In both examples, the gradient is written twice: the first is the CSS Images Level 3 method of repeating the color for each stop and the second example is the CSS Images Level 4 multiple color stop method of including two color-stop-lengths in a linear-color-stop declaration.</p>
+</div>
+
+<div>
+<h3 id="Controlling_the_progression_of_a_gradient">Controlling the progression of a gradient</h3>
+
+<p>By default, a gradient evenly progresses between the colors of two adjacent color stops, with the midpoint between those two color stops being the midpoint color value. You can control the interpolation, or progression, between two color stops by including a color hint location. In this example, the color reaches the midpoint between lime and cyan 20% of the way through the gradient rather than 50% of the way through. The second example does not contain the hint to hilight the difference the color hint can make:</p>

+
+<h3 id="Overlaying_gradients">Overlaying gradients</h3>
+
+<p>Gradients support transparency, so you can stack multiple backgrounds to achieve some pretty fancy effects. The backgrounds are stacked from top to bottom, with the first specified being on top.</p>

+<h2 id="Using_radial_gradients">Using radial gradients</h2>
+
+<p>Radial gradients are similar to linear gradients, except that they radiate out from a central point. You can dictate where that central point is. You can also make them circular or elliptical.</p>
+
+<h3 id="A_basic_radial_gradient">A basic radial gradient</h3>
+
+<p>As with linear gradients, all you need to create a radial gradient are two colors. By default, the center of the gradient is at the 50% 50% mark, and the gradient is elliptical matching the aspect ratio of it's box:</p>
+
+<div class="hidden">

+
+<h3 id="Positioning_radial_color_stops">Positioning radial color stops</h3>
+
+<p>Again like linear gradients, you can position each radial color stop with a percentage or absolute length.</p>

+
+<h3 id="Positioning_the_center_of_the_gradient">Positioning the center of the gradient</h3>
+
+<p>You can position the center of the gradient with keyterms, percentage, or absolute lengths, length and percentage values repeating if only one is present, otherwise in the order of position from the left and position from the top.</p>
+
+<div class="hidden">
+<pre class="brush: html notranslate">&lt;div class="radial-gradient"&gt;&lt;/div&gt;

+<h3 id="Sizing_radial_gradients">Sizing radial gradients</h3>
+
+<p>Unlike linear gradients, you can specify the size of radial gradients. Possible values include closest-corner, closest-side, farthest-corner, and farthest-side, with farthest-corner being the default.</p>
+
+<h4 id="Example_closest-side_for_ellipses">Example: closest-side for ellipses</h4>
+
+<p>This example uses the <code>closest-side</code> size value, which means the size is set by the distance from the starting point (the center) to the closest side of the enclosing box.</p>

+
+<h4 id="Example_farthest-corner_for_ellipses">Example: farthest-corner for ellipses</h4>
+
+<p>This example is similar to the previous one, except that its size is specified as <code>farthest-corner</code>, which sets the size of the gradient by the distance from the starting point to the farthest corner of the enclosing box from the starting point.</p>

+
+<h4 id="Example_closest-side_for_circles">Example: closest-side for circles</h4>
+
+<p>This example uses <code>closest-side</code>, which makes the circle's size to be the distance between the starting point (the center) and the closest side. The circle's radius is the distance between the center of the gradient and the closest edge, which due to the positioning of the 25% from the top and 25% from the bottom, is closest to the bottom, since the height in this case is narrower than the width.</p>

+<p>The {{cssxref("linear-gradient")}} and {{cssxref("radial-gradient")}} properties don't support automatically repeated color stops. However, the {{cssxref("repeating-linear-gradient")}} and {{cssxref("repeating-radial-gradient")}} properties are available to offer this functionality.</p>
+
+<p>The size of the gradient line that repeats is the length between the first color stop value and the last color stop length value. If the last color stop has just a color and no color stop length, the value defaults to 0, meaning the linear gradient will not repeat and the radial gradient will only repeat if the radius of the gradient is smaller than the length between the center of the gradient and the farthest corner.</p>

+<h3 id="Repeating_linear_gradients">Repeating linear gradients</h3>
+
+<p>This example uses {{cssxref("repeating-linear-gradient")}} to create a gradient that progresses repeatedly in a straight line. The colors get cycled over again as the gradient repeats. In this case the gradient line is 10px long.</p>

+<h3 id="Multiple_repeating_linear_gradients">Multiple repeating linear gradients</h3>
+
+<p>Similar to regular linear and radial gradients, you can include multiple gradients, one on top of the other. This only makes sense if the gradients are partially transparent allowing subsequent gradients to show through the transparent areas, or if you include different <a href="/en-US/docs/Web/CSS/background-size">background-sizes</a>, optionally with different <a href="/en-US/docs/Web/CSS/background-position">background-position</a> property values, for each gradient image. We are using transparency.</p>
+
+<p>In this case the gradient lines are 300px, 230px, and 300px long.</p>
