I created a round CSS-button, which works great:
HTML:
<div id="button" class="hide">
<ul class="nav">
<li><a class="icon-home" style="font-size:2em;"><i class="fa fa-search" style="position: absolute;top: 0.7em;left: 0.4em;"></i></a>
</li>
</ul>
</div>
CSS:
#button {
position: absolute;
bottom: 5px;
left: 0;
z-index: 1;
cursor: pointer;
}
.nav {
list-style: none;
text-align: center;
}
.nav li {
position: relative;
display: inline-block;
margin-right: -4px;
}
.nav a {
display: block;
background-color: #f7f7f7;
background-image: -webkit-gradient(linear, left top, left bottom, from(#f7f7f7), to(#e7e7e7));
background-image: -webkit-linear-gradient(top, #f7f7f7, #e7e7e7);
background-image: -moz-linear-gradient(top, #f7f7f7, #e7e7e7);
background-image: -ms-linear-gradient(top, #f7f7f7, #e7e7e7);
background-image: -o-linear-gradient(top, #f7f7f7, #e7e7e7);
color: #a7a7a7;
width: 70px;
height: 70px;
position: relative;
text-align: center;
line-height: 70px;
border-radius: 35px;
behavior: url(css/PIE.php);
box-shadow: 0px 3px 8px #aaa, inset 0px 2px 3px #fff;
}
.nav li:before {
content: "";
display: block;
#border-top: 1px solid #ddd;
border-bottom: 1px solid #fff;
width: 100%;
height: 1px;
position: absolute;
top: 50%;
z-index: -1;
}
.nav a:before {
content: "";
display: block;
background: #fff;
border-top: 2px solid #ddd;
position: absolute;
top: -18px;
left: -18px;
bottom: -18px;
right: -18px;
z-index: -1;
border-radius: 50%;
behavior: url(css/PIE.PHP);
box-shadow: inset 0px 8px 48px #f5f5f5;
}
The problem is, that this button also has to work in IE8. I already tried PIE as you see in the CSS (behavior). I also tried the jquery.corner.js-plugin. But both don't work. Maybe CSS-before makes some problem??
