I am trying to make CSS work on mobile browsers - forms

Question

My CSS is working perfectly fine on Google Chrome, Mozilla, and Opera. I have also tried Internet Explorer but that was a bust - Not that it matters.
My biggest issue right now is getting my CSS to work correctly on mobile safari (and other smartphone browsers like android).
HTML:
.load-more {
background-color: #00aa00;
color: #ffffff;
display: block;
font-family: 'Numans', sans-serif;
font-weight: lighter;
height: 3em;
line-height: 3em;
overflow: hidden;
padding: 0 3em;
text-align: center;
text-decoration: none;
transition: all .2s ease, background-color .01s ease, color .01s ease;
border-bottom: none;
}
.load-more.load-more--loading {
animation: rotate 1.5s linear infinite;
animation-delay: .2s;
background-color: transparent;
border: .3em solid #e1e1e1;
border-radius: 1.5em;
border-top-color: #00aa00;
box-sizing: border-box;
height: 3em;
color: transparent;
padding: 0;
pointer-events: none;
width: 3em;
-webkit-animation: rotation 2s infinite linear;
}
#-webkit-keyframes rotation {
from {
-webkit-transform: rotate(0deg);
}
to {
-webkit-transform: rotate(359deg);
}
}
<form action="stats.php" method="GET">
<div class="group">
<input type="text" name="player" autocomplete="off"><span class="highlight"></span><span class="bar"></span>
<label>USERNAME</label>
</div>
<center>
<input type="submit" value="CHECK STATS" class="load-more">
</a>
</center>
</form>
The CSS (and a javascript file that I'm using) turn the button into a loader when you click on it, but on mobile browsers like safari the button just disappears when you click it with no loader.

Answer 1

There's some support in iOS 7 and 8 for transform but none for animation in iOS. You're going to have to use jQuery or something to get the effect to work in mobile safari. Caniuse.com tells us the support here for these attributes: http://caniuse.com/#search=transform

This CSS works perfectly on mobile safari...
.load-more {
background-color: #00aa00;
color: #ffffff;
display: block;
font-family: 'Numans', sans-serif;
font-weight: lighter;
height: 3em;
line-height: 3em;
overflow: hidden;
padding: 0 3em;
text-align: center;
text-decoration: none;
border-bottom: none;
}
.load-more.load-more--loading {
background-color: transparent;
border: .3em solid #e1e1e1;
border-radius: 1.5em;
border-top-color: #00aa00;
box-sizing: border-box;
height: 3em;
color: transparent;
padding: 0;
pointer-events: none;
width: 3em;
-webkit-animation: rotation 2s infinite linear;
}
#-webkit-keyframes rotation {
from {-webkit-transform: rotate(0deg);}
to {-webkit-transform: rotate(359deg);}
}
