facebook style notification in html button using only hml and css - html

Question

I'm trying to build a button that has some notification attached to it and am trying to emulate the facebook notification styles. A little red circle in the top right corner with a number in it.
I'm having some issues with it though. I can't seem to get the circle in the right place or to get the number to actually sit inside of it.
my button looks like this
<button class="btn btn-blue" id="noteBtn">Notes <span class="notification">1</span></button>
and I've tred to do this with my css
.notification:before {
content: ' \25CF';
font-size: 5em;
color:red;
}
here is a js fiddle I was working with

Answer 1

<span> and I don't get along, so I changed it to a <div>

edit moved it out of the button a little bit, as requested.

Answer 2

To make it simple you don't need :before.
Add border-radius to the span, and to center the number use text-align: center
.notification {
border-radius: 30px;
text-align: center;
border: red;
width:20px;
height:10px;
background: red;
padding: 2px;
}

Answer 3

Change <span> to <div> and make button position:relative; and notification position:absolute; using CSS then put it wherever you want.

.button{
margin:20px 0px;
border:1px solid #e2e2e2;
background:#f9f9f9;
padding:5px 10px;
position:relative;
cursor:pointer;
transition:all 0.4s;
}
button:hover{
background:#333;
border:1px solid #333;
color:#fff;
}
.notifications {
position:absolute;
border-radius:2px;
font-size:14px;
background-color:red;
color:#fff;
padding:2px 5px;
top:-10px;
right:-10px;
}
<button class="button">
Notes<div class="notifications">1</div>
</button>
