I guess you mean something like this demo ?
If so you have to use the #keyframes element of CSS. More info on MDN or on CSS-Tricks.
CSS
.circle {
background: rgb(255, 255, 255);
border-radius: 100%;
cursor: pointer;
position: relative;
margin: 0 auto;
width: 15em;
height: 15em;
overflow: hidden;
-webkit-transform: translateZ(0);
-moz-transform: translateZ(0);
-ms-transform: translateZ(0);
transform: translateZ(0);
}
.circle h1 {
font-family:'Lato', sans-serif;
font-weight: 900;
font-size: 1.6em;
line-height: 8.2em;
text-align: center;
text-transform: uppercase;
-webkit-font-smoothing: antialiased;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
-webkit-animation: showText 2s infinite; /* Safari/Chrome 4+ */
-moz-animation: showText 2s infinite; /* Firefox 5+ */
-o-animation: showText 2s infinite; /* Opera 12+ */
animation: showText 2s infinite; /* IE 10+ */
animation-timing-function: ease-in-out;
/*

}
.circle:before, .circle:after {
border-radius: 100%;
