HTML / CSS: how to get fixed margin between body and footer

I am new to CSS and am trying to set up a page so that there is always a fixed margin / space between the main page content (sidebar / sections) and the footer (like 120px) which should work cross browser. Also, in case there is very little content on the page, the footer should always appear at least at the bottom of the (visible) screen.

I have made several attempts by applying the class "footer"

incl. following, but margin is always ignored.

My HTML structure (simplified):

<!DOCTYPE html>

    <html lang="en">
        <head>
            <meta charset="utf-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <!-- ... -->
        </head>
        <body>
            <nav>
                <!-- ... -->
            </nav>
            <section id="sidebar">
                <!-- ... -->
            </section>
            <section id="main">
                <!-- ... -->
            </section>
            <footer class="footer">
                <div>Some text</div>
            </footer>
        </body>
    </html>

My CSS:

.footer {
    color: #333;
    font-size: 11px;
    text-align: center;
    vertical-align: bottom
}
.footer:before {
    clear: both;
    display: block;
    height: 120px;
    min-height: 120px;
}

Can anyone help me? Also, if anything needs to change regarding my HTML, please let me know.

Thanks a lot in advance, Mike

This should help:

}
body {
    margin:0px;
    padding: 0px;
}
.wrap {
    height: auto;
    margin: 0 auto -80px; /* footer height + space */
    min-height: 100%;
    padding: 0 0 80px; /* footer height + space */
    box-sizing: border-box;
    overflow: auto;
}
.footer {
    background-color: #111111;
    color: #eeeeee;
    border-top: 1px solid red;
    height: 60px;  /* footer height */
    padding-top: 20px;
    display: block;
    margin-top: 20px; /* space between content and footer */
    box-sizing: border-box;
    position: relative;
    width: 100%;
}
      

        
        
        
      

    
<body>
    <div class="wrap">
        <nav>
            <!-- ... -->

Why are you using ": before"?

Your css should look like this:

.footer {
    color: #333;
    font-size: 11px;
    text-align: center;
    vertical-align: bottom;
    margin-top: 120px;
}


Try this example (works great for me). If it doesn't work - make sure you use css reset.

<!DOCTYPE html>

    <html lang="en">
        <head>
            <meta charset="utf-8" />
            <meta name="viewport" content="width=device-width, initial-scale=1.0">
            <!-- ... -->
        </head>
        <body>
            <nav style="background:grey;height:100px;">
                <!-- ... -->
            </nav>
            <section id="sidebar" style="background:green;height:100px;">
                <!-- ... -->
            </section>
            <section id="main" style="background:red;height:100px;">
                <!-- ... -->
            </section>
            <footer class="footer" style="background:blue;">
                <div>Some text</div>
            </footer>
        </body>
    </html>

<style>
.footer {
    color: #333;
    font-size: 11px;
    text-align: center;
    vertical-align: bottom;
    margin-top: 120px;
}

</style>

To add a border between body and footer, just add this to the footer section style: padding:20px 0px 0px 0px;

Keeping the footer down from the bottom is trickier. Try something like this for css:

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

#wrapper{              /*create a div around whole html body
    min-height:100%;
    position:relative;
}

#main{
    padding-bottom:100px; /* Height of the footer element */
}

#footer {
    width:100%;
    height:100px;
    position:absolute;
    bottom:0;
    left:0;
    color: #333;
}

just style the body with a 0px margin.

  body{
      margin: 0px;
  }
