I don't understand why my icon doesn't show up. I'm starting a new project and decided to try out initializr with bootstrap. Just can't make those icon appear. It's seems there's an invisible icon just before my text... I have check the documentation too, here. I also checked within my boostrap.less, sprites.less and variables.less (everything seems okay...).

My variable are correctly set and my image (PNG) are in my ../img folder.

// Sprite icons path
// -------------------------
@iconSpritePath:          "../img/glyphicons-halflings.png";
@iconWhiteSpritePath:     "../img/glyphicons-halflings-white.png";

Answer 1

I had to copy the img folder from bootstrap in the less folder... or you could change the variable to point to root/img folder.

Answer 2

In the newest Bootstrap icons are included with the new class glyphicon:

<i class="glyphicon glyphicon-heart"></i>

In some cases that will probably be the problem.

Answer 3

Open the rewrites.php file in the 'lib' folder. Add the following line within the function 'roots_add_rewrites($content)':

    'assets/fonts/(.*)'    => THEME_PATH . '/assets/fonts/$1',

The function should look like this:

function roots_add_rewrites($content) {
  global $wp_rewrite;
  $roots_new_non_wp_rules = array(
    'assets/css/(.*)'      => THEME_PATH . '/assets/css/$1',
    'assets/js/(.*)'       => THEME_PATH . '/assets/js/$1',
    'assets/img/(.*)'      => THEME_PATH . '/assets/img/$1',
    'assets/fonts/(.*)'    => THEME_PATH . '/assets/fonts/$1',
    'plugins/(.*)'         => RELATIVE_PLUGIN_PATH . '/$1'
  );
  $wp_rewrite->non_wp_rules = array_merge($wp_rewrite->non_wp_rules, $roots_new_non_wp_rules);
  return $content;
}

Answer 4

The file variables.less is at the bootstrap folder, so you need one more level to get to root.

Try to set the path to:

@iconSpritePath:          "../../img/glyphicons-halflings.png";
@iconWhiteSpritePath:     "../../img/glyphicons-halflings-white.png";
