Footer always on the boottom without display:fixed

问题

I want to make my footer display always on the bottom of the page even when the content does not fill the page, but when the content fills the page i want it to display only when i scroll to the very bottom of the page. I was thinking to check if the page can be scrolled with JavaScript and if no I'll add a class to make footer fixed else if yes ill remove that class, but I don't know how to check that with JavaScript. The idea is, I want my footer fixed when I cant scroll ,and when I can scroll I don't want it fixed. How can I do that ? My footer HTML is :

<footer class="smallFooter">
            <p> @EDUARDVALENTIN 2015 </p>
            <a href="https://www.facebook.com/danadesignsartoria?fref=ufi"><img src="img/fb-logo.png" /></a>
            <a href="#"><img src="img/instagram-logo.png" /></a>
            <a href="https://www.youtube.com/channel/UCqe4oWvPuSP8kTL70V1P9Gg/feed"><img src="img/yt-logo.png" /></a>
            <a href="https://twitter.com/SartoriaAsti"><img src="img/twitter-logo.png" /></a>
        </footer>

And CSS:

.smallFooter{   
    bottom:0;
    width:100%;  
    position:fixed;
    height:35px;
    background-color:#0E0E0E ;

}



.smallFooter p{
    position:absolute;
    display: inline-block;
    box-sizing:border-box;
    color:white;
    font-size:10px;
    float:left;

}


footer img{
    width:25x;
    height:25px;
    display:inline-block;
    float:right;
    margin-right:3%;
    padding-top:8px;

}

回答1:

Just set min-height in your "containter" element above your footer.

min-height: 100%

Set the position of your footer as absolute.

The solution I've used before is this sticky footer

The footer height needs to be known, and the most important pieces are the body height and wrapper with the min-height and negative margin-bottom.

回答3:

Get document height and other content height like in code

//$(".site_wrapper").height() -> Content height which is your center warraper
//$(".header_wrapper").height() ->  header wrapper height
//$(".header_wrapper").height() -> footer warpper height
//$(".site_wrapper").height() -> your complete page's wrraper
$(document).ready(function(){
if($(document).height() > $(".site_wrapper").height()){
            var dHeight = $(document).height();
            var fHeight = $(".footer_warpper").height();
            var hHeight = $(".header_wrapper").height();
            var height = dHeight -  (fHeight + hHeight) - 50; //adjust 50 +/- according to your page
            $(".main_table").css("height",height);
        }
});

For a CSS-only solution that doesn't depend on fixed height, use display: table.

CSS

html, body {
    height: 100%;
}
body {
    display: table;
    width: 100%;
}
.content {
    display: table-row;
    height: 100%;
}
.smallFooter {
    display: table-row;
    height: 1px;
}

HTML

<div class="content">
    <p>Main content goes here.</p>
</div>
<footer class="smallFooter">
    <p>Footer content goes here</p>
</footer>

**HTML**
<div class="mydiv">
  Suspendisse potenti.
</div>

<footer class="smallFooter">
        <p> @EDUARDVALENTIN 2015 </p>
        <a href="https://www.facebook.com/danadesignsartoria?fref=ufi"><img src="img/fb-logo.png" /></a>
        <a href="#"><img src="img/instagram-logo.png" /></a>
        <a href="https://www.youtube.com/channel/UCqe4oWvPuSP8kTL70V1P9Gg/feed"><img src="img/yt-logo.png" /></a>
        <a href="https://twitter.com/SartoriaAsti"><img src="img/twitter-logo.png" /></a>
    </footer>

CSS

html,body{
height:100%;
padding:0;
margin:0;
}
.mydiv{
    background : red;
}
.smallFooter{   
 width:100%;  
height:35px;
background-color:#0E0E0E ;
position:relative;
}



 .smallFooter p{
position:absolute;
display: inline-block;
box-sizing:border-box;
color:white;
font-size:10px;
float:left;

}


footer img{
width:25x;
height:25px;
display:inline-block;
float:right;
margin-right:3%;
padding-top:8px;

}

$(".mydiv").css({"min-height":($("body").outerHeight()-$(".smallFooter").outerHeight())});

You can try something like this as well using a little bit of Jquery. Does this help? Have the body take full height and the remaining contents take what is left.
