I am looking to create circular divs similar to the one in my code below. However, I want them to be stacked behind each other. Specifically, I would like a blue circle (that expands) positioned behind the current red circle but aligned center. The red circle should remain on top.
Below is the code snippet:
#circles
{
margin-right:auto;
margin-left:auto;
width:800px;
height:800px;
alignment-adjust:central;
}
.circle1
{position:relative;
margin-top:50%;
margin-right:auto;
margin-left:auto;
width:100px;
height:100px;
border-radius:50%;
background: #ff3019; /* Old browsers */
background: -moz-linear-gradient(top, #ff3019 0%, #cf0404 100%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ff3019), color-stop(100%,#cf0404)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top, #ff3019 0%,#cf0404 100%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top, #ff3019 0%,#cf0404 100%); /* Opera 11.10+ */
background: -ms-linear-gradient(top, #ff3019 0%,#cf0404 100%); /* IE10+ */
background: linear-gradient(to bottom, #ff3019 0%,#cf0404 100%); /* W3C */
transition:1s;
-moz-transition: 1s; /* Firefox 4 */
-webkit-transition: 1s; /* Safari and Chrome */
-o-transition: 1s; /* Opera */
-ms-transition: 1s; /* IE9 (maybe) */
}
