Only position the footer at the bottom if the page is considered "short."

Question

Only position the footer at the bottom if the page is considered "short."

I have a website that consists of multiple pages, each with varying heights.

My goal is to have the footer stay fixed at the bottom of the page if the content on the page does not fill up the browser viewport.

I attempted to achieve this using the following JavaScript:

$(function() {
  if ($(document).height() > $("footer").offset().top + 44) {
    $("footer").addClass('fixbottom');
  }
});

$(window).resize(function() {
  if ($(document).height() > $("footer").offset().top + 44) {
    $("footer").addClass('fixbottom');
  }
});

And the corresponding CSS:

.fixbottom {
  width: 100%;
  position: fixed;
  bottom: 0;
}

footer {
  height: 44px;
  background: #7abde9;
  color: #ffffff;
  text-align: center;
}

The `top+44` in my jQuery code accounts for the height of my footer. I included both document ready and window resize functions to cover all scenarios, but unfortunately, it doesn't seem to work as intended.

Any assistance would be greatly appreciated.

Answer №1

Forget about using javascript in this case.

Try out the "stickyfooter" method, a clever trick that ensures your footer always stays at the bottom of the page, even if your content is limited.

Check out this straightforward example:

html, body {
    height:100%;
}

#wrapper {
    position: relative;
    min-height:100%;
}

#main {
    padding-bottom: 44px;
}

footer {
    height: 44px;
    position: absolute;
    bottom: 0;
    left: 0;
    width: 100%;
}

If you're looking to resolve your issue, CSS is the way to go.

Make sure you have a separate element for your main content and another one for the footer at the bottom.

<div id="container">
  <div id="content">
    <div id="main">
      Your Content Here
    </div>
  </div>
  <div id="footer">
    Footer Section
  </div>
</div>

Set a min-height of 100% for #content and adjust the height and margin-top (equal to the height) for #footer. Also, include a margin-bottom to prevent overlapping with the last element in #content.

#content {
  min-height: 100%;
}
#footer {
  height: 3em;
  margin-top: -3em;
}
#main {
  padding-bottom: 3em;  /** height of #footer */
}

JS Fiddle Example

function checkContentHeight() {
    if($(window).height() > $('body').height()) {
        $('footer').addClass('shortContent');
    }
};

(function(){
    checkContentHeight();

    $(window).resize(function() {
        checkContentHeight();
    });
}());

This code simplifies the JavaScript and reduces the need for additional CSS styles.

@AnotherCoder, your implementation required jQuery for functionality.

A potential solution for the year 2020 could involve enclosing the non-footer content within a tag and specifying the minimum height of that tag to be equal to 100vh minus the height of the footer:

Sample HTML structure:

<main>
    <!--Content of the webpage-->
</main>

<footer>
    <!--Footer Content-->
</footer>

Corresponding CSS:

main {
    min-height: calc(100vh - <height of footer>);
}

This method does not require any JavaScript or jQuery.

I came up with a different approach to avoid using a big wrapper for everything:

html {
    position: relative;    /*Essential: prevents footer from aligning to :root, which is 100vh*/

    min-height: 100%;    /*even if the page is short, html will fill it up*/
}
body {
    margin-bottom: 10rem;    /*footer height (adjust using media queries if not fixed)*/
}
footer {
    position: absolute;
    bottom: 0;

    height: 10rem;    /*customize as needed, but keep in sync with body*/
}

Remember to set margin-bottom on body because the footer is positioned within the html tag, its direct parent.

Another way to accomplish this is by utilizing Flexbox, eliminating the need to manually specify the height of the footer.

HTML

<body>
  <header>Header</header>
  <main>Main</main>
  <footer>Footer</footer>
</body>

CSS

body {
    margin: 0;
    min-height: 100vh;
    display: flex;
    flex-direction: column;
}

main {
    flex: 1;
}
