Linking CSS button to email - How can it be done?

I'm trying to link the submit button to be an email address. But can't
seem to get it to work.
Any suggestions on what I may be doing wrong?
It looks like it works on first inspection, but whenever I upload it to
the site it doesn't work =S
Here is the HTML:
<a href="mailto:email@email.co"><input type="submit" value="Get In Touch"
name="submit" class="submit" id="submit"></a>
Below is the CSS:
body {
font-family: 'Lucida Grande', 'Helvetica Neue', Helvetica, Arial, sans-serif;
padding: 100px;
font-size: 13px;
}
div {
background: #fff;
margin: 0 auto;
width: 200px;
padding: 100px;
text-align: center;
/* border-radius */
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
/* box-shadow */
-webkit-box-shadow: rgba(0,0,0,0.2) 0px 1px 3px;
-moz-box-shadow: rgba(0,0,0,0.2) 0px 1px 3px;
box-shadow: rgba(0,0,0,0.2) 0px 1px 3px;
}
input[type="submit"] {
height: 50px;
padding: 0 48px; margin: 10px auto 0 auto;
background: #090a0b;
border: 0;
text-transform: uppercase;
font-family: "Open Sans";
font-size: 24px;
color: #fff;
font-weight: 400;
cursor: pointer;
-webkit-transition: all 0.2s ease;
-moz-transition: all 0.2s ease;
-o-transition: all 0.2s ease;
transition: all 0.2s ease;
opacity: 1;
-webkit-appearance: none;
border: solid 1px #fff;
-webkit-border-radius: 1px;
-moz-border-radius: 1px;
border-radius: 1px;
background: transparent;
}
