Overlapping centered divs with flexbox? - css

Question

I'm trying to make a responsive "listening" loader but I'm having some issues trying to center all 3 elements.
See the "clean" JSFiddle here: http://jsfiddle.net/mfaeqxn9/ (the mic, needs to be in the center of the loader).
This is the CSS:
body{
background: #151515
}
#listenericon{
color:#23d05f;
font-size:82px;
}
.circle {
background-color: rgba(0,0,0,0);
border: 20px solid rgba(35,208,95,0.9);
opacity: .9;
border-right: 20px solid rgba(0,0,0,0);
border-left: 20px solid rgba(0,0,0,0);
border-radius: 999px;
width: 200px;
height: 200px;
margin: 0 auto;
-moz-animation: spinPulse 1s infinite ease-in-out;
-webkit-animation: spinPulse 1s infinite linear;
}
.circle1 {
background-color: rgba(0,0,0,0);
border: 20px solid rgba(35,208,95,0.9);
opacity: .9;
border-left: 20px solid rgba(0,0,0,0);
border-right: 20px solid rgba(0,0,0,0);
border-radius: 999px;
width: 120px;
height: 120px;
margin: 0 auto;
position: relative;
top: -288px;
-moz-animation: spinoffPulse 1s infinite linear;
-webkit-animation: spinoffPulse 1s infinite linear;
}
#-moz-keyframes spinPulse {
0% {
-moz-transform: rotate(160deg);
opacity: 0;
box-shadow: 0 0 1px #23d05f;
}
50% {
-moz-transform: rotate(145deg);
opacity: 1;
}
100% {
-moz-transform: rotate(-320deg);
opacity: 0;
};
}
#-moz-keyframes spinoffPulse {
0% {
-moz-transform: rotate(0deg);
}
100% {
-moz-transform: rotate(360deg);
};
}
#-webkit-keyframes spinPulse {
0% {
-webkit-transform: rotate(160deg);
opacity: 0;
box-shadow: 0 0 1px #23d05f;
}
50% {
-webkit-transform: rotate(145deg);
opacity: 1;
}
100% {
-webkit-transform: rotate(-320deg);
opacity: 0;
};
}
#-webkit-keyframes spinoffPulse {
0% {
-webkit-transform: rotate(0deg);
}
100% {
-webkit-transform: rotate(360deg);
};
}
#import url(https://fonts.googleapis.com/icon?family=Material+Icons);
.material-icons {
font-family: 'Material Icons';
font-weight: normal;
font-style: normal;
font-size: 24px; /* Preferred icon size */
display: inline-block;
width: 1em;
height: 1em;
line-height: 1;
text-transform: none;
letter-spacing: normal;
word-wrap: normal;
/* Support for all WebKit browsers. */
-webkit-font-smoothing: antialiased;
/* Support for Safari and Chrome. */
text-rendering: optimizeLegibility;
/* Support for Firefox. */
-moz-osx-font-smoothing: grayscale;
/* Support for IE. */
font-feature-settings: 'liga';
}
I've tried the translate 50% version and many others, but since it needs to be responsive I have yet to find a proper solution. I'm fine with flexbox, but so far I havent figured out how to make the divs overlap each other.
Anyone have a good solution for this?

Answer 1

Here's the solution (I have updated the codes as your requirement):
Working demo
#listenericon{
color:#23d05f;
font-size:82px;
margin-top:10px;
width:120px;
display: block;
position: relative;
margin: 0 auto;
padding-top: 78px; }
.mic{
position: absolute;
top: 0;
left: 0;
width:100%; }

Answer 2

Fully Responsive Check Running Code, Two Main Issues : Use Position Absolute if you want to overlap two divs , and control that divs using position relative , check : Fiddle Code
<div class="loader">
<div class="circle"></div>
<div class="circle1"><i id="listenericon" class="material-icons">mic</i></div>
#listenericon{
color:#23d05f;
font-size:82px; margin:10px 0 0 0;
}
.loader{position:relative; float:left; width:100%; height:270px;}
