You'll need to animate the background as a moving gradient since cohost only let's you animate position (afaik). prechoster will help. I can send an example in a bit.

`<div style="position:relative;height:200px;">

<div style="position:relative;height:60000px;background-image:linear-gradient(#333CCC, #33CC36, #B8CC33, #FCCA00, #33CC36, #333CCC);animation: 18s spin linear infinite; transform:translateY(-58800px)">

<div style="height:0;">

<div id="gradient-awesome" style="position:relative;height:16300px;background-image:linear-gradient(orange, purple, red, cadetblue, yellow, coral, green, cyan, deeppink, dodgerblue, orange);animation: 30s spin linear infinite; transform:translateY(-16000px)">

</div>

<p style="position:absolute;top:0;left:30px;font-family:Comic Sans MS;font-size:36pt;background-image:-moz-element(#user-content-gradient-awesome), linear-gradient(red, blue); color:transparent; -webkit-background-clip:text; -webkit-text-stroke:1px black;">vantablack

</div>

it uses gradients scrolling really fast to simulate a real gradient, and it's also really busted because you can't like add normal text at any point in the post. and also uses firefox exclusive experimental css for the text so it doesn't work for ... most people
