Put text at bottom of div

I have 4 DIV's right next to each other, and they're all centered in the middle of the screen. I have 2 words in each div, but I don't want them at the top, I want them to appear in the bottom right hand corner of the div. How can I do this?

Wrap the text in a span or similar and use the following CSS:

.your-div {
    position: relative;
}

.your-div span {
    position: absolute;
    bottom: 0;
    right: 0;
}

<div id="container">
    <div><span>Two Words</span></div>
    <div><span>Two Words</span></div>
    <div><span>Two Words</span></div>
    <div><span>Two Words</span></div>
</div>

#container{
    width:450px;
    height:200px;
    margin:0px auto;
    border:1px solid red;
}

#container div{
    position:relative;
    width:100px;
    height:100px;
    border:1px solid #ccc;
    float:left;
    margin-right:5px;
}
#container div span{
    position:absolute;
    bottom:0;
    right:0;
}

If you only have one line of text and your div has a fixed height, you can do this:

div {
    line-height: (2*height - font-size);
    text-align: right;
}

See fiddle.

Thanks @Harry the following code works for me:

.your-div{
   vertical-align: bottom;
   display: table-cell;
}

I think that's better to use flex boxes (compatibility) than the absolute position. Here's example from me in pure css.

.container{
  background-color:green;
  height:500px;
  
  /*FLEX BOX */
  display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
    -webkit-flex-direction: column;
    -ms-flex-direction: column;
    flex-direction: column;
    -webkit-flex-wrap: nowrap;
    -ms-flex-wrap: nowrap;
    flex-wrap: nowrap;
    -webkit-justify-content: flex-start;
    -ms-flex-pack: start;
    justify-content: flex-start;
    -webkit-align-content: stretch;
    -ms-flex-line-pack: stretch;
    align-content: stretch;
    -webkit-align-items: flex-start;
    -ms-flex-align: start;
    align-items: flex-start;
}

.elem1{
  background-color:red;
  padding:20px;
  
   /*FLEX BOX CHILD */
 -webkit-order: 0;
    -ms-flex-order: 0;
    order: 0;
    -webkit-flex: 0 1 auto;
    -ms-flex: 0 1 auto;
    flex: 0 1 auto;
    -webkit-align-self: flex-end;
    -ms-flex-item-align: end;
    align-self: flex-end;
 
}

<div class="container">
 TOP OF CONTAINER 
<div class="elem1">
  Nam pretium turpis et arcu. Sed a libero. Sed mollis, eros et ultrices tempus, mauris ipsum aliquam libero, non adipiscing dolor urna a orci.

Mauris sollicitudin fermentum libero. Pellentesque libero tortor, tincidunt et, tincidunt eget, semper nec, quam. Quisque id mi.
