Horizontal timeline in pure css

Question

I'm trying to make a timeline in pure CSS however I seem to be running into some problems.

When I try to set the timeline div as overflow-x: scroll it still scrolls on the y access.

This is what I've got:

#timeline {
  height: 500px;
  width: auto;
  margin: 0;
  background: red;
}

.event {
  height: 500px;
}

.founded {
  width: 400px;
  float: left;
  background: blue;
}

.grant {
  width: 800px;
  background: yellow;
}

<ol id="timeline">
  <li class="event founded"></li>
  <li class="event grant"></li>
</ol>

I just want each additional entry to follow the previous one and for it all be scroll-able horizontally. If anyone could point me in the right direction that would be amazing.

Thanks.

I literally JUST had to make one of these. This is what I came up with:

body {
  padding: 25px;
  font-family: sans-serif;
}

.timeline {
  white-space: nowrap;
  overflow-x: scroll;
  padding: 30px 0 10px 0;
  position: relative;
}

.entry {
  display: inline-block;
  vertical-align: top;
  background: #13519C;
  color: #fff;
  padding: 10px;
  font-size: 12px;
  text-align: center;
  position: relative;
  border-top: 4px solid #06182E;
  border-radius: 3px;
  min-width: 200px;
  max-width: 500px;
}

.entry img {
  display: block;
  max-width: 100%;
  height: auto;
  margin-bottom: 10px;
}

.entry:after {
  content: '';
  display: block;
  background: #eee;
  width: 7px;
  height: 7px;
  border-radius: 6px;
  border: 3px solid #06182E;
  position: absolute;
  left: 50%;
  top: -30px;
  margin-left: -6px;
}

.entry:before {
  content: '';
  display: block;
  background: #06182E;
  width: 5px;
  height: 20px;
  position: absolute;
  left: 50%;
  top: -20px;
  margin-left: -2px;
}

.entry h1 {
  color: #fff;
  font-size: 18px;
  font-family: Georgia, serif;
  font-weight: bold;
  margin-bottom: 10px;
}

.entry h2 {
  letter-spacing: .2em;
  margin-bottom: 10px;
  font-size: 14px;
}

.bar {
  height: 4px;
  background: #eee;
  width: 100%;
  position: relative;
  top: 13px;
  left: 0;
}

<div class="bar"></div>
<div class="timeline">
  <div class="entry">
    <h1>1990</h1>
    <h2>Entry Title</h2>
    <img src="http://dummyimage.com/300x200/000/fff" /> Here's the info about this date

  <div class="entry">
