How to make the footer always at the bottom

I'm making a website, and I'm trying to make the footer always at the bottom. I want it so that the footer is always at the bottom at the browser window, but if the content is long enough, it will push the footer out of sight and further bottom. Right now, the footer is always positioned immediately after the content above it.

enter image description here

I tried setting display: flex, flex-direction, align-items: flex-end, margin-bottom: 0px, but it didn't work. I'm also trying to avoid setting fixed heights.

App.css

* {
    font-family: 'Lato', sans-serif;
}

html, body {
    height: 100%;
    margin: 0px;
}

body {
    display: flex;
    flex-direction: column;
}

.container {
    flex: 1 0 auto;
    margin: 0px auto;
    width: 65%;
}
Solution

  • Try flex-direction: column;.

    document.getElementById('add').addEventListener('click', e => {
  document.getElementById('content').innerHTML += '<br />content<br />content<br />content';
});
    html,
body {
  margin: 0;
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
}

.content {
  flex: 1 0 auto;
}

.footer {
  background: #999;
  flex-shrink: 0;
}
    <body>
  <div class="content">
    <button id="add">Add Content</button>
    <p id="content">content</p>
  </div>
  <footer class="footer">footer</footer>
</body>
