Answer 1

The problem is that you have -webkit-animation-duration: 5000; instead of -webkit-animation-duration: 5000ms;:
... and you might also want to support other browsers
.logo {
top: 35%;
left: 70%;
position: absolute;
-webkit-animation-name: spin;
-webkit-animation-duration: 5000ms;
-webkit-animation-iteration-count: infinite;
-webkit-animation-timing-function: ease-in;
-moz-animation-name: spin;
-moz-animation-duration: 5000ms;
-moz-animation-iteration-count: infinite;
-moz-animation-timing-function: ease-in;
-ms-animation-name: spin;
-ms-animation-duration: 5000ms;
-ms-animation-iteration-count: infinite;
-ms-animation-timing-function: ease-in;
}
#-moz-keyframes spin {
from {
-moz-transform: rotate(0deg);
}
to {
-moz-transform: rotate(360deg);
}
}
#-webkit-keyframes spin {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(360deg);
}
}
#keyframes spin {
from {
transform: rotate(0deg);
}
to {
transform: rotate(360deg);
}
}
nav ul {
-webkit-font-smoothing: antialiased;
text-shadow: 0 1px 0 black;
background: #bcab98;
list-style: none;
margin: 0;
padding: 0;
width: 100%;

Answer 2

Use this way. You are not putting all the vendor prefixes and the duration should have units: 5000ms or 5s:
.element-animation {
animation: animationFrames linear 4s;
animation-iteration-count: infinite;
transform-origin: 50% 50%;
-webkit-animation: animationFrames linear 4s;
-webkit-animation-iteration-count: infinite;
-webkit-transform-origin: 50% 50%;
-moz-animation: animationFrames linear 4s;
-moz-animation-iteration-count: infinite;
-moz-transform-origin: 50% 50%;
-o-animation: animationFrames linear 4s;
-o-animation-iteration-count: infinite;
-o-transform-origin: 50% 50%;
-ms-animation: animationFrames linear 4s;
-ms-animation-iteration-count: infinite;
-ms-transform-origin: 50% 50%;
width: 50px; line-height: 50px; background: #99f; text-align: center;
}
#keyframes animationFrames {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
#-moz-keyframes animationFrames {
0% {
-moz-transform: rotate(0deg);
}
100% {
-moz-transform: rotate(360deg);
}
}
#-webkit-keyframes animationFrames {
0% {
-webkit-transform: rotate(0deg);
}
100% {
-webkit-transform: rotate(360deg);
}
}
#-o-keyframes animationFrames {
0% {
-o-transform: rotate(0deg);
}
100% {
-o-transform: rotate(360deg);
}
}
#-ms-keyframes animationFrames {
0% {
-ms-transform: rotate(0deg);
}
100% {
-ms-transform: rotate(360deg);
}
}
<div class="element-animation">Logo</div>
