Vertical scrollbar appears for unknown reason

What causes vertical scrollbar to appear here? http://codepen.io/anon/pen/QGByOQ?editors=1100

As I suggest, .container is 100% height of body, body inherits html, html is 100% of the viewport, hence every .chart should fit perfectly as it's height is half of the .container's. Nevertheless a y-scrollbar appears. What's the behavior behind this?

html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
</head>
<body>
    <div class="container">
        <div class="chart1"></div>
        <div class="chart1"></div>
        <div class="chart1"></div>
        <div class="chart1"></div>
    </div>
</body>
</html>

css:

.container {
  width: 100%;
  height: 100%;
  border: 5px dashed black;
  box-sizing: border-box;
  font-size: 0;
  overflow: auto;
}

html, body {
  height: 100%;
}

body {
  margin: 0;
}

.chart1 {
  display: inline-block;
  width: 50%;
  height: 50%;
  border: 1px solid red;
  box-sizing: border-box;
}

This is due to the red border of the container. Use CSS calc() function, like:

.chart1 {
  height: calc(100% - 1px); /* 1px for the extra border */
}

Have a look at the snippet below:

.container {
  width: 100%;
  height: 100%;
  border: 5px dashed black;
  box-sizing: border-box;
  font-size: 0;
  overflow: auto;
}

html, body {
  height: 100%;
}

body {
  margin: 0;
}

.chart1 {
  display: inline-block;
  width: 50%;
  height: calc(50% - 1px);
  border: 1px solid red;
  box-sizing: border-box;
}
<div class="container">
  <div class="chart1"></div>
  <div class="chart1"></div>
  <div class="chart1"></div>
  <div class="chart1"></div>
</div>

Hope this helps!
