Aligning graphic to the right of text and centering to create button - can't centre button

Question

http://codepen.io/gingerman/pen/VevZLR ( best to look at the code here )

When you open the codepen you'll see that the button is aligned left.

I'm having problems centring the button_container without the point of the button falling off.

I have searched for help on StackOverFlow, but not found a solution.

Thanks :)

CSS

#button_container{
  position:absolute;
  text-align: center;
  top: 68px;

You can use flex on parent element with id #content_dc and remove css rule for element with id #button_container:

/*REMOVE THIS
#button_container{
  position:absolute;
  text-align: center;
  top: 68px;
}*/

/*check comments in this rule*/
#content_dc {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0px;
  left: 0px;
  background-color: #ee1a36;
  z-index: 100;
  -webkit-backface-visibility: hidden;
  backface-visibility: hidden;
  text-align: center;
  display: flex;/*add flex*/
  justify-content: center; /*add justify-content center*/
  align-items: center; /*add align-items center*/
}

#button_join {
  display: inline-block;
  font-size: 14px;
  font-weight: bold;
  color: #000;
  font-family: Helvetica, Arial, sans-serif;
  background-color: #fff;
  line-height: 31px;
  padding-left: 10px;
  border-radius: 8px 0px 0px 8px;
  border: 0 0 0 0;
}
#button_point {
  float: right;
  display: inline-block;
  height: 31px;
}
/* Default style, feel free to remove if not needed. */

body,
body * {
  vertical-align: baseline;
  border: 0;
  outline: 0;
  padding: 0;
  margin: 0;
}
/* Div layer for the entire banner. */

#container_dc {
  position: absolute;
  width: 118px;
  height: 200px;
  border: 1px solid #850f1e;
  top: 0px;
  left: 0px;
  margin: auto;
  overflow: hidden;
  font-family: Helvetica, Arial, sans-serif;
  font-weight: 400;
  color: #fff;
}

<div id="container_dc">

  <div id="content_dc">

    <div id="button_container">
      <div id="button_join">centre me</div>
      <img id="button_point" alt="" title="" src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/269240/button_end_36_high.png" />
