HTML

<div id="page"><div id="results"><div class="result">1+2</div>

<div class="result">y=mx+b</div></div><input id="eq" type="text" autofocus=""></div>

CSS

@import url(http://fonts.googleapis.com/css?family=Rokkitt);
body {
  background-color: #444047;
  margin: 0;
  padding: 0;
}
#page {
  width: 40%;
  background-color: #ececec;
  position: fixed;
  top: 0;
  bottom: 0;
  left: 50%;
  margin-left: -20%;
}
#results {
  position: absolute;
  top: 0;
  right: 0;
  left: 0;
  bottom: 75px;
}
#eq {
  width: 96%;
  margin-left: -48%;
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  -webkit-border-radius: 20px;
  -moz-border-radius: 20px;
  -ms-border-radius: 20px;
  -o-border-radius: 20px;
  border-radius: 20px;
  border-width: 2px;
  border-color: #9A9A9A #EEEEEE #EEEEEE #9A9A9A;
  border-style: solid;
  font-family: 'Rokkitt', serif;
  letter-spacing: 1px;
  font-size: 24pt;
  padding: 5px 10px;
  position: absolute;
  bottom: 10px;
  left: 50%;
}
#eq:focus {
  border-color: #4E9FF2 #84B2E0 #84B2E0 #4E9FF2;
  -webkit-box-shadow: 0 0 10px #007eff;
  -moz-box-shadow: 0 0 10px #007eff;
  -ms-box-shadow: 0 0 10px #007eff;
  -o-box-shadow: 0 0 10px #007eff;
  box-shadow: 0 0 10px #007eff;
  outline: none;
}
#results {
  font-family: 'Rokkitt', serif;
  font-size: 16pt;
  vertical-align: bottom;
  text-align: left;
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  padding: 5px;
  display: table-cell;
  overflow: auto;
}
.result {
  padding: 2px;
}
.result + .result {
  border-top: 1px dotted gray;
}

How can I align the .result divs to the bottom of the #result container?

Edit: The #results div needs to gain a scrollbar if there are too many .results to fit. overflow:auto seems to be incompatible with some of the solutions below.

Answer 1

Here's a version which doesn't break your overflow: auto.

Here's a jsFiddle.

Basically what I'm doing is wrapping your markup in enough div's so that I can make the wrapper div's behave like a table, with the display: table;, display: table-row; and display: table-cell; CSS properties.

Now that the wrapping markup behaves like a table, I can absolutely position a div inside the "cell" in the top "row" and set it to stick to the bottom with a max-height of 100% and its overflow set to auto. This is the exact same technique I used in the original answer I posted here. But now the max-height of 100% will stay inside the top row of the table, eliminating the issues which you pointed out with the solutions I posted earlier.

Here are the relevant CSS classes:

#page {
    width: 40%;
    background-color: #ececec;
    position: fixed;
    bottom: 0;
    left: 50%;
    margin-left: -20%;
    display: table;
    height: 100%;
}
#results, #input {
    display: table-row;
}
#results > div {
    display: table-cell;
    height: 100%;
    position:relative;
}
#results > div > div {
    overflow: auto;
    max-height: 100%;
    width: 100%;
    position: absolute;
    bottom: 0px;
}
#input {
    height: 75px;
}
#results {
    font-family:'Rokkitt', serif;
    font-size: 16pt;
    vertical-align: bottom;
    text-align: left;
    box-sizing: border-box;
    -moz-box-sizing: border-box;
    -webkit-box-sizing: border-box;
    overflow: auto;
    height: 100%;
}

And here's the edited HTML:

<div id="page">
    <div id="results">
        <div>
            <div>
                <div class="result">1+2</div>
                <div class="result">3*4</div>
                <div class="result">5/9</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">y=mx+b</div>
                <div class="result">1+2</div>
            </div>
        </div>
    </div>
    <div id="input">
        <input id="eq" type="text" autofocus="" />
    </div>
</div>

Answer 2

Lets clean up your mess, wrap the inner container which is position: absolute; in a position: relative; container, I've made this from scratch, you can have a look

Demo

<div class="wrap">
    <div class="inner_wrap">
        <span>1+2</span>
        <span>3*4</span>
        <span>5/9</span>
        <span>y=mx+b</span>
        <span><input id="eq" type="text" autofocus="" /></span>
    </div>
</div>

CSS (Excluding input element style, but I've included that in the demo fiddle)

html, body {
    background-color: #444047;
    height: 100%;
}

.wrap {
    width: 230px;
    background: #ECECEC;
    height: 100%;
    margin: auto;
    position: relative;
}

.wrap span {
    display: block;
    border-bottom: 1px dotted #515151;
    padding: 5px;
    font-size: 18px;
    font-family: Arial;
}

div span:last-child {
    border-bottom: 0;    
}

.inner_wrap {
    position: absolute;
    bottom: 0;
}
