CSS Question

Animate text fill from left to right

I wanted to animate a the text fill with CSS. The Text should be filled with color from left to right.

this is my 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;

Now only the first letter is color-filled.

here is the fiddle

you may also take a look at flex (for centering things) and mix-blend-mode, so it can be avalaible also for Firefox:

.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;
  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;
<div class="box-with-text">
