How to stick a footer to bottom in css?

Viewed 139320

I am having the classic problem for the positioning of a Footer on the bottom of the browser. I've tried methods including http://ryanfait.com/resources/footer-stick-to-bottom-of-page/ but to no good result: my footer always keeps appearing in the middle of the browser window in both FF and IE.

In the HTML i got this simple structure

<form>
 ...
 <div class=Main />
 <div id=Footer />
</form>

Here is the css code that is relevant for the css footer problem:

    *
    {
        margin: 0;
    }


html, body
{
    height: 100%;
}


    #Footer
    {
        background-color: #004669;
        font-family: Tahoma, Arial;
        font-size: 0.7em;
        color: White;
        position: relative;
        height: 4em;
    }



    .Main
    {
        position:relative;
        min-height:100%;
        height:auto !important;
        height:100%;

        /*top: 50px;*/

        margin: 0 25% -4em 25%;

        font-family: Verdana, Arial, Tahoma, Times New Roman;
        font-size: 0.8em;
        word-spacing: 1px;
        line-height: 170%;
        /*padding-bottom: 40px;*/
    }

Where am I doing wrong? I really have tried everything. If I missed any useful info please let me know.

Thank you for any suggestion in advance.

Regards,


thank you all for your answers. it worked with:

position:absolute;
    width:100%;
    bottom:0px;

setting position:fixed did not work in IE for some reason(Still showed footer in the middle of the browser), only worked for FF.

Assuming you know the size of your footer, you can do this:

    footer {
        position: sticky;
        height: 100px;
        top: calc( 100vh - 100px );
    }

For modern browser, you can use flex layout to ensure the footer stays at the bottom no matter the content length (and the bottom won't hide the content if it is too long)

HTML Layout:

<div class="layout-wrapper">
  <header>My header</header>
  <section class="page-content">My Main page content</section>
  <footer>My footer</footer>
</div>

CSS:

html, body {
  min-height: 100vh;
  width: 100%;
  padding: 0;
  margin: 0;
}

.layout-wrapper {
    min-height: 100vh;
    display: flex;
    flex-direction: column;
    justify-content: space-between;
}

.layout-wrapper > .page-content {
  background: cornflowerblue;
  color: white;
  padding: 20px;
}

.layout-wrapper > header, .layout-wrapper > footer {
  background: #C0C0C0;
  padding: 20px 0;
}

So a Mixed Solution from @nvdo and @Abdelhameed Mahmoud worked for me

footer {
    position: sticky;
    height: 100px;
    top: calc( 100vh - 100px );
}

Try position attribute with fixed value to put your division in a fixed position. Following is the code for putting your footer at bottom of the page.

footer {
    position: fixed; 
    bottom: 0;
}

If you use the "position:fixed; bottom:0;" your footer will always show at the bottom and will hide your content if the page is longer than the browser window.

I agree with Luke Vo's solution. I thought it would better to omit justify-content: space-between; from layout-wrapper and add margin-top: auto; to footer.

You wouldn't want your body to be hanging in the middle and only have footer pushed to the bottom.

This approach addresses any content extending beyond the viewport.

The following code works, which is from w3schools.com

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.footer {
   position: fixed;
   left: 0;
   bottom: 0;
   width: 100%;
   background-color: red;
   color: white;
   text-align: center;
}
</style>
</head>
<body>

<h2>Fixed/Sticky Footer Example</h2>
<p>The footer is placed at the bottom of the page.</p>

<div class="footer">
  <p>Footer</p>
</div>

</body>
</html>
