Twitter Bootstrap图标栏不显示

Question

Only 2 of my three icon-bars show when I resize my browser. Previous answers show that people have not put their icon-bars in the right nav tag, however I have done this and it is all correct. My website is viewable here, but here is my code for header.php too:

  <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" 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> <div id="logo"> <a href="http://http://www.franhaines.co.uk/paddlethewye/"/> <img src="wp-content/themes/BareTheme/logo.png" alt="Paddle the Wye Logo" border="0" /></a> </div> </div> 

Answer 1

You overide the bootstrap styles with your own stylesheet.

You must remove or specify your code ( http://www.franhaines.co.uk/style.css ) like so:

span:not(.icon-bar) {
  color: #fff;
  font-family: centrale_sans_regularregular, helvetica;
  font-size: 30px;
  z-index: 80;
  position: absolute;
  display: block;
  top: 50%;
  text-align: center;
  width: 100%;
}

Answer 2

I found this rule on your page:

span {
  color: #fff;
  display: block;
  font-family: centrale_sans_regularregular,helvetica;
  font-size: 30px;
  position: absolute;
  text-align: center;
  top: 50%;
  width: 100%;
  z-index: 80;

}

from bootstrap.

The position absolute is breaking it; override position to be static or unset for span.icon-bar and it'll fix it.

Answer 3

Same Code Works Fine For Me.

 <link href = "http://netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css" rel = "stylesheet"> <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" 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> <div id="logo"> <a href="http://http://www.franhaines.co.uk/paddlethewye/"/> <img src="wp-content/themes/BareTheme/logo.png" alt="Paddle the Wye Logo" border="0" /></a> </div> </div>
