  • <gradient> CSS 数据类型 是 <image> 的一种特殊类型，包含两种或多种颜色的过渡转变。
  • 渐变可以在任何使用 <image> 的地方使用，例如在背景中。
  • 渐变没有内在尺寸，实际大小取决于所应用的元素的大小。

线性渐变 🔗

由 linear-gradient()函数创建，在一个假想的直线上进行线性过渡的图像。

  • 💠 语法：linear-gradient( <angle>｜ to <side-or-corner> (可选) , <color-stop-list>);

    • background-image: linear-gradient(#8A2387, #E94057, #F27121);

  • 🤖 值详解

    • ✋🏻 <angle>｜ to <side-or-corner> (可选)

      👉🏻 默认情况下，线性渐变的方向是从上到下,可以指定一个值来改变渐变的方向。

      • <side-or-corner> ：渐变线的起始点位置。

        • 如果指定了，则包含 to 和两个关键字：

          • 一个指定水平位置（left 或 right） ，另一个指定竖直位置（top 或 bottom）。
          • 关键词的先后顺序无影响。

        • 如果没有指定，则默认为 to bottom。

          • to top、to bottom、to left 和 to right 分别等价于
          • 0deg、180deg、270deg 和 90deg。其余值会被转换为角度。

      • <angle> 🔗：渐变线的方向的角度。

        • 0deg 等价于 to top，增加值相当于顺时针旋转。

    • ✋🏻 <color-stop-list>:
      <color-stop-list> = <linear-color-stop> , [ <linear-color-hint>? , <linear-color-stop> ]#

      • <linear-color-stop> : 色标的 <color> 值，然后是一个或两个可选的色标位置（沿渐变轴的 百分比 或 绝对长度值）。
        • 💛 色标（color stop）: 要创建最基本的渐变类型，你只需指定两种颜色即可。这些被称为色标。
        • 至少指定两个色标，也可以指定任意数量。
        • 色标位置 ：可以为径向和线性渐变设置 0、1 或 2 个百分比值 或者绝对长度值 来调整它们的位置。
          • 如果将位置设置为百分数，0% 表示起始点，而 100% 表示终点。
          • 如果有些位置不需要明确设置，那么将会自动计算，第一个色标在 0% 处，最后一个色标在 100%，其他的色标则位于其相邻的两个色标中间。
      • linear-color-hint : <length-percentage> 百分比（percentage）或长度（length）值。

        • 插值提示，定义渐变色在相邻色标之间的渐变过程。

        • 其中的长度定义了渐变色应在两个色标之间的哪个点到达颜色过渡的中点。

          • 如果省略该值，颜色过渡的中点就是两个色标之间的中点。
          css 复制代码

❤️‍🔥 线性重复渐变 repeating-linear-gradient() 🔗

💚 repeating-linear-gradient() 创建一个能够重复填满容器的线性渐变。

  • 重复渐变的长度是第一个色标和最后一个色标之间的距离

  • 如果第一种颜色没有色标长度，则色标长度默认为 0。

  • 每次重复时，色标的位置都会以基本线性渐变长度的倍数移动。

  • 因此，每个结束色标的位置都会与起始色标的位置重合；

    • 如果色值不同，就会产生鲜明的视觉过渡。

      • 可以通过重复第一种颜色值作为最后一种颜色值来改变这种情况。

径向渐变 🔗

由 radial-gradient() 函数创建，该图像由从原点辐射的两种或多种颜色之间的渐进过渡组成，其形状可以是圆形或椭圆形。

🔸 径向渐变没有内在尺寸，也就是说，它没有固有或首选的尺寸，也没有首选的比例，其实际大小取决于所应用的元素的大小。

😶‍🌫️ radial-gradient(circle at center, red 0, blue, green 100%) 表示在容器中心的渐变，从红色开始，变成蓝色，最后变成绿色

  • 💠 语法 : radial-gradient( [ <radial-gradient-syntax> ] )

    • radial-gradient() 函数接收一个 <radial-gradient-syntax> 参数。

    • <radial-gradient-syntax> = [ <rg-ending-shape> || <rg-size> ]? [ at <position> ]? ,<color-stop-list>

      • [ <结束形状> || <大小> ]？[at <位置>]？,<色标列表>

径向渐变通过指定渐变的中心（0% 椭圆所在的位置）和结束形状（100% 椭圆）的大小和形状来指定。

  • 🤖 值详解：

    • <ending-shape> : 渐变结束时的形状。

      • 两个值 circle | ellipse
      • circle: 圆形，渐变的形状是一个半径不变的正圆
      • ellipse 椭圆，渐变形状是轴对称椭圆。
        -如果没有指定，默认为ellipse。

    • <size> :定义了渐变的尺寸。确定渐变结束形状的大小，它决定了渐变的大小如何相对于其容器。

      • 如果省略，则默认为最远角（farthest-corner）。

      • 它可以显式给出，也可以通过关键字给出。

        • 就关键字定义而言，渐变框边缘应视为向两个方向无限延伸，而不是有限线段。

      • 🍑 关键字

        关键字 描述
        closest-side 渐变结束形状如果是 圆形，与容器距离渐变中心点最近的一边相切，如果是椭圆，则与距离渐变中心点最近的垂直和水平边相切。
        closest-corner 渐变结束形状与容器距离渐变中心点最近的一个角相交。
        farthest-side 类似于 closest-side，但是结束形状与容器距离渐变中心点最远的一边（或最远的垂直和水平边）相切。
        farthest-corner 默认值，渐变的结束形状与容器距离渐变中心点最远的一个角相交。

      • 🍑 长度值和百分比

        • 🙌🏻 如果 ending-shape 被指定为 circle，则可以为大小指定一个长度值，它明确了圆的半径。负值是无效的。
        • 🙌🏻 如果 ending-shape 被指定为 ellipse，则可以使用带有两个值的长度或百分比来指定椭圆的大小 。
          • 第一个值表示水平半径，第二个值表示垂直半径。
          • 百分比值是相对于渐变框在相应维度上的大小的。负值是无效的。
          • 🙌🏻 如果 ending-shape 关键词被省略，渐变形状会由给定的大小决定。
            • 一个 长度值 产生圆
            • 两个 长度或者百分比 单位的值产生椭圆。
            • 一个 百分比 值是无效的。

锥形渐变 🔗

由 conic-gradient() 函数创建，创建一个由渐变组成的图像，渐变的颜色围绕一个中心点旋转（而不是从中心辐射）进行过渡。

😶‍🌫️ 锥形渐变的例子包括饼图和色轮 ，但是也可以用于创建棋盘格和其他有趣的效果。

🔸 锥形渐变的语法和径向渐变的语法类似，但是色标是围绕渐变弧（圆的圆周）进行的 ，而不是从渐变中心出现的渐变线上，并且色标是百分比或度数：绝对长度无效。

🔸 默认情况下，渐变的中心位于 50% 50% 的位置，渐变的开始点是朝上的。
conic-gradient(#8A2387, #E94057, #F27121)

  • 💠 语法 : conic-gradient( [ <conic-gradient-syntax> ] )

    • conic-gradient()函数接受一个 <conic-gradient-syntax>参数

    • <conic-gradient-syntax> :

      [ [ [ from <angle> ]? [ at <position> ]? ] || <color-interpolation-method> ]? , <angular-color-stop-list>

  • 🤖 值详解：

    • from <angle> : 定义了锥形渐变的角度起点，以角度作为单位（0 到 360）。

      • 默认值为 0，定义顺时针方向的渐变旋转。
      • <angle>的取值 🔗
        • deg : 度。一个完整的圆是 360deg。
        • grad : 百分度。一个完整的圆是 400grad。
        • rad : 弧度。一个完整的圆是 2π 弧度，约等于 6.2832rad。1rad 是 180/π 度 => 180 deg = 1rad * π 。
        • turn : 圈数。一个完整的圆是 1turn。
          45deg = 50grad = 1/4π = 6.2832rad/8 = 1/8 turn

    • angular-color-stop-list : 定义了一系列颜色及其在渐变中的位置。每个颜色后面跟着一个百分比或长度值来指定该颜色在渐变中出现的位置。

      • <angular-color-stop-list> = <angular-color-stop> , [ <angular-color-hint>? , <angular-color-stop> ]#

      • <angular-color-stop> : 色标（color stop）的 <color> 值，然后是一个或两个可选的色标位置（沿着渐变圆周轴的 <angle>）。

      • <color-hint> : 插值提示，定义了在相邻色标之间的渐变如何进行。

        • 这个长度定义了渐变色应在两个色标之间的哪一点到达颜色过渡的中点。
        • 如果省略，颜色过渡的中点是两个色标之间的中点。

❤️‍🔥 重复锥形渐变 repeating-conic-gradient() 🔗

💚 repeating-conic-gradient 是 CSS3 中的一个函数，用于创建重复的圆锥渐变。这种类型的渐变可以用于创建环状、螺旋状或其他基于角度的颜色过渡效果。

  • 与线性渐变和径向渐变不同，圆锥渐变是沿着一个角度或方向进行的，并且颜色在每个 360 度周期内都会重复。
