问题:

I am using Bootstrap 3 for a site I am designing.

I want to have a footer like this sample. Sample

Please note that I don't want it FIXED so bootstrap navbar-fixed-bottom does not solve my problem. I just want it to be always at the bottom of the content and also be responsive.

Any guide will be very much appreciated.

EDIT:

Sorry if I wasn't clear. What happens now is that when the content body does not have enough content. My footer moves up and then it leaves an empty space at the bottom.

This is what i have now for my navbar

<nav class="navbar navbar-inverse navbar-bottom" style="padding:0 0 120px 0">
        <div class="container">
            <div class="row">
                <div class="col-sm-4">
                    <h5 id='footer-header'> SITEMAP </h3>
                    <div class="col-sm-4" style="padding: 0 0 0 0px">
                        <p>News</p>
                        <p>contact</p>
                    </div>
                    <div class="col-sm-4" style="padding: 0 0 0 0px">
                        <p>FAQ</p>
                        <p>Privacy Policy</p>
                    </div>
                </div>
                <div class="col-sm-4">
                    <h5 id='footer-header'> xxxx </h3>
                    <p>yyyyyyyyyyyyy</p>
                </div>
                <div class="col-sm-4">
                    <h5 id='footer-header'> xxxxx </h3>
                    <p>uuuuuuuuuuuuuuu</p>
                </div>
            </div>
        </div>
    </nav>

CSS

.navbar-bottom {
min-height: 300px;
margin-top: 100px;
background-color: #28364f;
padding-top: 35px;
color:#FFFFFF;
}

See the example below. This will position your Footer to stick to bottom if the page has less content and behave like a normal footer if the page has more content.

CSS

* {
    margin: 0;
}
html, body {
    height: 100%;
}
.wrapper {
    min-height: 100%;
    height: 100%;
    margin: 0 auto -155px; /* the bottom margin is the negative value of the footer's height */
}
.footer, .push {
    height: 155px; /* .push must be the same height as .footer */
}

HTML

<div class="wrapper">
  <p>Your website content here.</p>
  <div class="push"></div>
</div>
<div class="footer">
  <p>Copyright (c) 2008</p>
</div>

UPDATE: New version of Bootstrap demonstrates how to add sticky footer without adding a wrapper. Please see Jboy Flaga's Answer for more details.

There is a simplified solution from bootstrap here (where you don't need to create a new class): http://getbootstrap.com/examples/sticky-footer-navbar/

When you open that page, right click on a browser and "View Source" and open the sticky-footer-navbar.css file (http://getbootstrap.com/examples/sticky-footer-navbar/sticky-footer-navbar.css)

you can see that you only need this CSS

/* Sticky footer styles
-------------------------------------------------- */
html {
  position: relative;
  min-height: 100%;
}
body {
  /* Margin bottom by footer height */
  margin-bottom: 60px;
}
.footer {
  position: absolute;
  bottom: 0;
  width: 100%;
  /* Set the fixed height of the footer here */
  height: 60px;
  background-color: #f5f5f5;
}

for this HTML

<html>
    ...
    <body>
        <!-- Begin page content -->
        <div class="container">
        </div>
        ...

        <footer class="footer">
        </footer>
    </body>
</html>

UPDATE: This does not directly answer the question in its entirety, but others may find this useful.

This is the HTML for your responsive footer

<footer class="footer navbar-fixed-bottom">
     <div class="container">
     </div>
</footer>

For the CSS

footer{
    width:100%;
    min-height:100px;    
    background-color: #222; /* This color gets inverted color or you can add navbar inverse class in html */
}

NOTE: At the time of the posting for this question the above lines of code does not push the footer below the page content; but it will keep your footer from crawling midway up the page when there is little content on the page. For an example that does push the footer below the page content take a look here http://getbootstrap.com/examples/sticky-footer/



回答4:

use flexbox as you can use it at your disposal. The solution offered by bootstrap 4 still hunting overlap content in responsive layout, e.g: it will break in mobile view, i come across the most neat trick is to use flexbox solution demo shown at here:(https://philipwalton.github.io/solved-by-flexbox/demos/sticky-footer/) this way we do not have to deal with fixed height issue which is an obsolete solution by now...this solution works for bootstrap 3 and 4 whichever you using.

<body class="Site">
  <header>…</header>
  <main class="Site-content">…</main>
  <footer>…</footer>
</body>

.Site {
  display: flex;
  min-height: 100vh;
  flex-direction: column;
}

.Site-content {
  flex: 1;
}


回答5:

For people still struggling and the answered solution doesn't work quite as you want it to, here is the simplest solution I have found.

Wrap your main content and assign it a min view height. Adjust the 60 to whatever value your style needs.

<div id="content" style="min-height:60vh"></div>
<div id="footer"></div>

Thats it and it works pretty well.

Galen Gidman has posted a really good solution to the problem of a responsive sticky footer that does not have a fixed height. You can find his full solution on his blog: http://galengidman.com/2014/03/25/responsive-flexible-height-sticky-footers-in-css/

HTML

<header class="page-row">
  <h1>Site Title</h1>
</header>

<main class="page-row page-row-expanded">
  <p>Page content goes here.</p>
</main>

<footer class="page-row">
  <p>Copyright, blah blah blah.</p>
</footer>

CSS

html,
body { height: 100%; }

body {
  display: table;
  width: 100%;
}

.page-row {
  display: table-row;
  height: 1px;
}

.page-row-expanded { height: 100%; }


回答7:

This method uses minimal markup. Just put all your content in a .wrapper which has a padding-bottom and negative margin-bottom equal to the footer height (in my example 100px).

html, body {
    height: 100%;
}

/* give the wrapper a padding-bottom and negative margin-bottom equal to the footer height */

.wrapper {
    min-height: 100%;
    height: auto;
    margin: 0 auto -100px;
    padding-bottom: 100px;
}
.footer {
    height: 100px;
}

<body>

<div class="wrapper">
  <p>Your website content here.</p>
</div>
<div class="footer">
   <p>Copyright (c) 2014</p>
</div>

</body>

For Bootstrap:

<div class="navbar-fixed-bottom row-fluid">
  <div class="navbar-inner">
    <div class="container">
      Text
    </div>
  </div>
</div>

The major flaw of the solutions above is they have a fixed height for the footer.
And that just doesn't cut it in the real world, where people use a zillion number of devices and have this bad habit of rotating them when you least expect it and **Poof!** there goes your page content behind the footer!

In the real world, you need a function that calculates the height of the footer and dynamically adjusts the page content's padding-bottom to accommodate that height. And you need to run this tiny function on page load and resize events as well as on footer's DOMSubtreeModified (just in case your footer gets dynamically updated asynchronously or it contains animated elements that change size when interacted with).

Here's a proof of concept, using jQuery v3.0.0 and Bootstrap v4-alpha, but there is no reason why it shouldn't work on lower versions of each.

jQuery(document).ready(function( $ ) {
  $.fn.accomodateFooter = function(){
    var footerHeight = $('footer').outerHeight();
    $(this).css({'padding-bottom':footerHeight+'px'});
  }
  // accomodate footer after its html has changed
  $('footer').on('DOMSubtreeModified', function(){
    $('body').accomodateFooter();
  })
  // accomodate footer on page load and resize
  $(window).on('load resize', function(){
    $('body').accomodateFooter();
  })
  $('body').accomodateFooter();
  window.addMoreContentToFooter = function() {
    var f = $('footer');
    f.append($('<p />',{
      text:"Human give me attention meow flop over sun bathe licks your face wake up wander around the house making large amounts of noise jump on top of your human's bed and fall asleep again. Throwup on your pillow sun bathe. The dog smells bad jump around on couch, meow constantly until given food, so nap all day, yet hiss at vacuum cleaner."}))
    .append($('<hr />'));
  }
});
body {
  min-height: 100vh;
  position: relative;
  padding-top: 54px;
}
footer {
  background-color: rgba(0,0,0,.65);
  color: white;
  position: absolute;
  bottom: 0;
  width: 100%;
  padding: 1.5rem;
  display: block;
}
footer hr {
  border-top: 1px solid rgba(0,0,0,.42);
  border-bottom: 1px solid rgba(255,255,255,.21);
}

<footer>I am a footer with dynamic content.
  <hr />

Initially, I have posted this solution here but I realized it might help more people if posted under this question.

Note: I have purposefully wrapped the $([selector]).accomodateFooter() as a jQuery plugin, so it could be run on any DOM element, as in most layouts it is not the $('body')'s bottom-padding that needs adjusting, but some page wrapper element with position:relative (usually the immediate parent of the footer).

None of these solutions exactly worked for me perfectly because I used navbar-inverse class in my footer. But I did get a solution that worked and Javascript-free. Used Chrome to aid in forming media queries. The height of the footer changes as the screen resizes so you have to pay attention to that and adjust accordingly. Your footer content (I set id="footer" to define my content) should use postion=absolute and bottom=0 to keep it at the bottom. Also width:100%. Here is my CSS with media queries. You'll have to adjust min-width and max-width and add or remove some elements:

#footer {
  position: absolute;
  color:  #ffffff;
  width: 100%;
  bottom: 0; 
}
@media only screen and (min-width:1px) and (max-width: 407px)  {
    body {
        margin-bottom: 275px;
    }

    #footer {
        height: 270px; 
    }
}
@media only screen and (min-width:408px) and (max-width: 768px)  {
    body {
        margin-bottom: 245px;
    }

    #footer {
        height: 240px; 
    }
}
@media only screen and (min-width:769px)   {
    body {
        margin-bottom: 125px;
    }

    #footer {
        height: 120px; 
    }
}

Or this

<footer class="navbar navbar-default navbar-fixed-bottom">
    <p class="text-muted" align="center">This is a footer</p>
</footer>
