Ok got your question updated my answer accordingly, the best and the least you can do it is like this

Demo

Actual Markup + Styles Required (Don't use it unless and until CSS3 animations are fully supported by all browsers)

HTML

<div class="out"><span>example</span></div>

CSS

div {
   animation:demo 7s;
   -moz-animation:demo 7s; /* Firefox */
   -webkit-animation:demo 7s; /* Safari and Chrome */
   -o-animation:demo 7s; /* Opera */
   animation:demo 7s infinite;
}

@keyframes demo {
   0% {opacity:0;}
   50% {opacity:1;}
   100% {opacity:0;}
}

@-moz-keyframes demo { /* Firefox */
   0% {opacity:0;}
   50% {opacity:1;}
   100% {opacity:0;}
}

@-webkit-keyframes demo { /* Safari and Chrome */
   0% {opacity:0;}
   50% {opacity:1;}
   100% {opacity:0;}
}

@-o-keyframes demo { /* Opera */
   0% {opacity:0;}
   50% {opacity:1;}
   100% {opacity:0;}
}
