Add a logo in front of the brand name using bootstrap 3

I started with the following code, that should generate the navigation bar of my site using Jekyll (and bootstrap):

  <nav class="navbar navbar-default" role="navigation">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#jb-navbar-collapse">
        <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="{{ HOME_PATH }}">{{ site.title }}</a>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="jb-navbar-collapse">
      <ul class="nav navbar-nav">
        {% assign pages_list = site.pages %}
        {% assign group = 'navigation' %}
        {% include JB/pages_list %}
      </ul>
    </div><!-- /.navbar-collapse -->
  </nav>

However, I want to have a logo in front of {{ site .title }}. To that end, I tried to use the following code:

 <nav class="navbar navbar-default" role="navigation">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#jb-navbar-collapse">
        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
      <div style="text-align:left">
        <a href="{{ HOME_PATH }}"><img src="{{ site.logoimg }}" height="5%" width="5%"/></a>
        <a class="navbar-brand" href="{{ HOME_PATH }}">{{ site.title }}</a>
      </div>
    </div>

    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="jb-navbar-collapse">
      <ul class="nav navbar-nav">
        {% assign pages_list = site.pages %}
        {% assign group = 'navigation' %}
        {% include JB/pages_list %}
      </ul>
    </div><!-- /.navbar-collapse -->
  </nav>

The problems are:

1. The logo is to the right of the text
2. Now there's a huge horizontal space between the text+logo and the pages' names.

I guess it is something simple, but I don't know how to tackle it. How can I place the logo to the left of the text and avoid the bad h-spacing. A bonus would be to make sure that the line of text is v-centered with respect to the logo.

Try To Give Fixed values to img widht & height

it is giving exact space of your image's actual width!

.navbar-brand-fix,
.navbar-nav-fix li a
{
  line-height:50px !important;
  vertical-align:middle !important;
  padding-top:25px !important;
}

      </button>
