Mobile Primary Menu Button

Does anybody have an idea?

1. Create a child theme.
2. Make a copy of header.php from the parent theme folder into your child theme’s folder.
3. In the child theme copy of header.php, look for this line, and remove the word Primary:

   <button class="menu-toggle"><?php _e( 'Primary Menu', 'twentyfourteen' ); ?></button>

   Make sure to click the Update File button when you’re done.

4. In the child theme’s style.css file, add these rules:

   .menu-toggle {
      text-transform: none;
   }
   .menu-toggle:before {
      content: none;
   }

   You can add whatever other properties you want to the first rule to customize the Menu however you want (like font-size, color, etc).

Thank you. Worked very well.
