To display a signup button on your website, you can create a container div and place it in your page.php, single.php, index.php, or header.php file for site-wide visibility. Here is some sample code for you to use:
HTML
<div class="signup">
<a class="signupbtn" href="#" title="Sign up">Sign Up</a>
</div>
CSS
.signup {
position:fixed;
left:0;
top:160px;
}
a.signupbtn {
color: #6e6e6e;
font: bold 12px Helvetica, Arial, sans-serif;
text-decoration: none;
padding: 7px 12px;
position: relative;
display: inline-block;
text-shadow: 0 1px 0 #fff;
-webkit-transition: border-color .218s;
-moz-transition: border .218s;
-o-transition: border-color .218s;
transition: border-color .218s;
background: #f3f3f3;
background: -webkit-gradient(linear,0% 40%,0% 70%,from(#F5F5F5),to(#F1F1F1));
background: -moz-linear-gradient(linear,0% 40%,0% 70%,from(#F5F5F5),to(#F1F1F1));
border: solid 1px #dcdcdc;
-webkit-border-top-right-radius: 8px;
-webkit-border-bottom-right-radius: 8px;
-moz-border-radius-topright: 8px;
-moz-border-radius-bottomright: 8px;
border-top-right-radius: 8px;
border-bottom-right-radius: 8px;
margin-right: 10px;
}
a.signupbtn:hover {
color: #333;
border-color: #999;
-moz-box-shadow: 0 2px 0 rgba(0, 0, 0, 0.2) -webkit-box-shadow:0 2px 5px rgba(0, 0, 0, 0.2);
box-shadow: 0 1px 2px rgba(0, 0, 0, 0.15);
}
a.signupbtn:active {

border-color: #444;
}
