CSS circle mask

Question

I am looking to create a dark mask at the bottom of a circle that is contained in the main circle.

can you do this using css masks?

Please see fiddle

<div id="profile-pic-wrap">
  <div id="profile-pic">
    <div class="profile-btn-bg">
      <a href="#" class="profile-pic-btn">Change Profile</a>
    </div>
  </div>
</div>

Thanks

You can use overflow:hidden; :

DEMO

changes to your CSS : added overflow:hidden; and text-align:center to #profile-pic

#profile-pic {
	position: absolute;
	z-index: 999;
	width: 200px;
	height: 200px;
	left: 33px;
	background: #FFF;
	border: 3px solid #FFF;
	border-radius: 100px;
	-webkit-border-radius: 100px;
	-moz-border-radius: 100px;
	top: 0px;
	position: relative;
    background:red;
    overflow:hidden;
    text-align:center;
}
.profile-btn-bg{
	position: absolute;
	background-color: black;
	width: 100%;
	height: 30%;
	bottom: 0px;
}

a.profile-pic-btn{
	color: #fff;
    
}

<div id="profile-pic-wrap">
  <div id="profile-pic">
    <div class="profile-btn-bg">
      <a href="#" class="profile-pic-btn">Change Profile</a>
    </div>
  </div>
</div>
