Question

我想用CSS动画文本填充。文本应从左到右填充颜色。

这是我的CSS：

.box-with-text {
    background-image: -webkit-linear-gradient(right, crimson 50%, white 50%);
    background-repeat: repeat;
    background-position: 0 0;
    background-size: 200% 100%;
    -webkit-text-fill-color: transparent;
    -webkit-background-clip: text;
    -webkit-animation: stripes normal forwards ease-in-out;
    animation: stripes 2s normal forwards ease-in-out;
}

现在只有第一个字母填充颜色。

你也可以看一下flex（用于居中）和mix-blend-mode，所以对于Firefox来说它也是可用的：

＆＃13;

.box-with-text {
  text-transform: uppercase;
  font: bold 26vmax/.8 Open Sans, Impact;
  background: black;
  display: table;
  color: white;
  mix-blend-mode: multiply
}

@-webkit-keyframes stripes {
  to {
    background-size:100% 100%;
  }
}

@keyframes stripes {
  to {
    background-size:100% 100%;
  }
}

html {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-align:center;
  -webkit-align-items:center;
      -ms-flex-align:center;
          align-items:center;
  height: 100%;
  background: black;
}

body {
  margin: auto;
  background: -webkit-linear-gradient( crimson , crimson) turquoise no-repeat 0 0;
  background: linear-gradient( crimson , crimson) turquoise no-repeat 0 0;
  background-size: 0 100%;
  -webkit-animation: stripes 2s linear infinite;
          animation: stripes 2s linear infinite;
}

＆＃13;

<div class="box-with-text">
  Text
</div>

＆＃13;

/* Main styles */
@import url(http://fonts.googleapis.com/css?family=Open+Sans:800);

.box-with-text {
  background-image: -webkit-linear-gradient(left, crimson 50%, white 50%);
  background-repeat: repeat;
  background-position: 0 0;
  background-size: 100% 200px;
  -webkit-text-fill-color: transparent;
  -webkit-background-clip: text;
  -webkit-animation: stripes 2s linear infinite;
  animation: stripes 2s linear infinite;
}

@-webkit-keyframes stripes {
  100% {
    background-position: 0 -50px;
  }
}

@keyframes stripes {
  100% {
    background-position: 385px 0;
  }
}
/* Other stuff */
body {
  overflow: hidden;
  background: #000;
  color: #FFF;
}

.box-with-text {
  position: absolute;
  top: 50%;
  left: 50%;
  white-space: nowrap;
  text-align: center;
  text-transform: uppercase;
  font: bold 26vmax/.8 Open Sans, Impact;
  -webkit-transform: translateX(-50%) translateY(-50%);
  -ms-transform: translateX(-50%) translateY(-50%);
  transform: translateX(-50%) translateY(-50%);
}

<div class="box-with-text">
  Text
</div>

在这种情况下，您应该更改

@keyframes stripes {
  100% {
    background-position: 385px 0;
  }
}

位置取决于文字宽度;

动画文本填充从左到右
