html - 使用自定义动画使模态变大

Question

所以基本上我正在尝试从这个 website 复制“果冻”动画.在我的 HTML 中，我有来自 bootstrap 的 bootstrap modal 的基本示例。这:

.animation-target {
  animation: animation 1000ms linear both;
}

@keyframes animation {
  0% {
    transform: matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
  }
  3.4% {
    transform: matrix3d(1.316, 0, 0, 0, 0, 1.407, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
  }
  4.7% {
    transform: matrix3d(1.45, 0, 0, 0, 0, 1.599, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1);
  }
  6.81% {

  10.21% {

当我添加动画时，模态和文本似乎非常大，我不明白为什么会这样。这是 JSFiddle 上的重现.

Answer 1

bouncejs 的果冻动画将使元素的大小加倍，因此您会看到模态和文本看起来非常大。

一种方法是修改 matrix3d 以将大小减小一半。 https://jsfiddle.net/0nyL9dc7/

@keyframes animation { 
  0% { transform: matrix3d(.5, 0, 0, 0, 0, .5, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  3.4% { transform: matrix3d(0.658, 0, 0, 0, 0, 0.703, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  4.7% { transform: matrix3d(0.72, 0, 0, 0, 0, 0.8, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  6.81% { transform: matrix3d(0.83, 0, 0, 0, 0, 0.946, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  9.41% { transform: matrix3d(0.941, 0, 0, 0, 0, 1.084, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  10.21% { transform: matrix3d(0.971, 0, 0, 0, 0, 1.113, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  13.61% { transform: matrix3d(1.061, 0, 0, 0, 0, 1.166, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  14.11% { transform: matrix3d(1.070, 0, 0, 0, 0, 1.165, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  17.52% { transform: matrix3d(1.104, 0, 0, 0, 0, 1.12, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  18.72% { transform: matrix3d(1.106, 0, 0, 0, 0, 1.093, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  21.32% { transform: matrix3d(1.098, 0, 0, 0, 0, 1.034, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  24.32% { transform: matrix3d(1.075, 0, 0, 0, 0, 0.98, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  25.23% { transform: matrix3d(1.067, 0, 0, 0, 0, 0.969, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  29.03% { transform: matrix3d(1.031, 0, 0, 0, 0, 0.948, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  29.93% { transform: matrix3d(1.024, 0, 0, 0, 0, 0.949, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  35.54% { transform: matrix3d(0.990, 0, 0, 0, 0, 0.981, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  36.74% { transform: matrix3d(0.986, 0, 0, 0, 0, 0.99, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  41.04% { transform: matrix3d(0.980, 0, 0, 0, 0, 1.011, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  44.44% { transform: matrix3d(0.983, 0, 0, 0, 0, 1.016, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  52.15% { transform: matrix3d(0.995, 0, 0, 0, 0, 1.003, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  59.86% { transform: matrix3d(1.003, 0, 0, 0, 0, 0.99, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  63.26% { transform: matrix3d(1.003, 0, 0, 0, 0, 0.996, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  75.28% { transform: matrix3d(1.001, 0, 0, 0, 0, 1.001, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  85.49% { transform: matrix3d(0.999, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  90.69% { transform: matrix3d(0.999, 0, 0, 0, 0, 0.999, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  100% { transform: matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); } 
}

另一种方法是在动画关键帧中的transform中添加scale(.5)，将尺寸缩小一半。 https://jsfiddle.net/0cdahvx1/1/

@keyframes animation { 
  0% { transform: scale(.5) matrix3d(1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  3.4% { transform: scale(.5) matrix3d(1.316, 0, 0, 0, 0, 1.407, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  4.7% { transform: scale(.5) matrix3d(1.45, 0, 0, 0, 0, 1.599, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  6.81% { transform: scale(.5) matrix3d(1.659, 0, 0, 0, 0, 1.893, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  9.41% { transform: scale(.5) matrix3d(1.883, 0, 0, 0, 0, 2.168, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
  10.21% { transform: scale(.5) matrix3d(1.942, 0, 0, 0, 0, 2.226, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }

  17.52% { transform: scale(.5) matrix3d(2.208, 0, 0, 0, 0, 2.239, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1); }
