我有这个代码:

HTML:
<nav class="navbar navbar-default" role="navigation"> <div class="container-fluid"> <!-- Brand and toggle get grouped for better mobile display --> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="#">Brand</a> </div> <!-- Collect the nav links,forms,and other content for toggling --> <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> <ul class="nav navbar-nav"> <li class="active"><a href="#">Link</a></li> <li><a href="#">Link</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> <li class="divider"></li> <li><a href="#">One more separated link</a></li> </ul> </li> </ul> <form class="navbar-form navbar-left" role="search"> <div class="form-group"> <input type="text" class="form-control" placeholder="Search"> </div> <button type="submit" class="btn btn-default">Submit</button> </form> <ul class="nav navbar-nav navbar-right"> <li><a href="#">Link</a></li> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <span class="caret"></span></a> <ul class="dropdown-menu" role="menu"> <li><a href="#">Action</a></li> <li><a href="#">Another action</a></li> <li><a href="#">Something else here</a></li> <li class="divider"></li> <li><a href="#">Separated link</a></li> </ul> </li> </ul> </div><!-- /.navbar-collapse --> </div><!-- /.container-fluid --> </nav> <div class="container"> <p>Here comes some content.</p> <p>Here comes some content.</p> <p>Here comes some content.</p> <p>Here comes some content.</p> <p>Here comes some content.</p> </div> <footer> <div class="container"> <div class="row"> <div class="col-md-8"> <p>Some footer-content</p> <p>Some footer-content</p> <p>Some footer-content</p> </div> <div class="col-md-4"> <p>Some footer-content</p> <p>Some footer-content</p> </div> </div> </div> </footer>
CSS:
footer { background-color: #eee; padding-top: 15px; padding-left: 15px; }
这是我所拥有的最基本的东西,但你会明白这一点.
正如您所看到的,页脚位于空中某处.
我可以将它定位为绝对并使其容易粘,但由于各种原因我不想要那样.
我希望页脚低于整个内容(可以说,列为最后一个),但是,如果没有足够的内容我需要将页脚放在底部:0和左:0.
我不知道如何做到这一点.我的第一个猜测是使用JavaScript来查看有多少空间以及网站是否可滚动.
