##### Basic syntax highlighter

Prism is a lightweight, extensible syntax highlighter, built with modern web standards in mind. To highlight code syntax, add `.language-*` class to the `<code>` element. By default, highlighter displays a small text block with current language on the top right corner. This functionality is an extra option, provided by "Show language" prism.js addon.

Example

    <!-- Navbar markup -->
    <div class="navbar navbar-inverse">
    	<div class="navbar-header">
    		<a href="index.html" class="navbar-brand">
    			<img src="assets/images/logo_light.png" alt="Logo">
    		</a>
    	</div>

    	<div class="navbar-collapse collapse" id="navbar-mobile">
    		<ul class="nav navbar-nav">
    			<li>...</li>
    			<li class="dropdown">...</li>
    		</ul>

    		<div class="navbar-right">
    			<ul class="nav navbar-nav navbar-left">
    				<li>...</li>
    				<li class="dropdown">...</li>
    			</ul>
    		</div>
    	</div>
    </div>
    <!-- /navbar markup -->

##### Line highlight

Highlights specific lines and/or line ranges with light green color and displays start and end line numbers. To highlight specific line, add `data-line="*"` attribute, to highlight line ranges add `data-line="*-*"` attribute. Multiple lines or ranges are also supported, to use just separate values with comma: `data-line="*, *-*"`. This prism addon is included to the current plugin build by default.

Example

    <!-- Navbar markup -->
    <div class="navbar navbar-inverse">
    	<div class="navbar-header">
    		<a href="index.html" class="navbar-brand">
    			<img src="assets/images/logo_light.png" alt="Logo">
    		</a>
    	</div>

    	<div class="navbar-collapse collapse" id="navbar-mobile">
    		<ul class="nav navbar-nav">
    			<li>...</li>
    			<li class="dropdown">...</li>
    		</ul>

    		<div class="navbar-right">
    			<ul class="nav navbar-nav navbar-left">
    				<li>...</li>
    				<li class="dropdown">...</li>
    			</ul>
    		</div>
    	</div>
    </div>
    <!-- /navbar markup -->

##### Line numbers

Line number at the beginning of code lines. Obviously, this is supposed to work only for code blocks - `<pre><code>` - and not for inline code. To use this feature, add `.line-numbers` class to your desired `<pre>` element and line-numbers plugin will take care. This prism addon is included to the current plugin build by default.

Example

    <!-- Navbar markup -->
    <div class="navbar navbar-inverse">
    	<div class="navbar-header">
    		<a href="index.html" class="navbar-brand">
    			<img src="assets/images/logo_light.png" alt="Logo">
    		</a>
    	</div>

    	<div class="navbar-collapse collapse" id="navbar-mobile">
    		<ul class="nav navbar-nav">
    			<li>...</li>
    			<li class="dropdown">...</li>
    		</ul>

    		<div class="navbar-right">
    			<ul class="nav navbar-nav navbar-left">
    				<li>...</li>
    				<li class="dropdown">...</li>
    			</ul>
    		</div>
    	</div>
    </div>
    <!-- /navbar markup -->

##### Define starting line

Defines starting line number at the beginning of code lines. This feature works as an optional addition to the `line number` plugin. To set a custom starting line number, add `data-start="*"` attribute to the code block markup and it will shift the line counter. Negative values are also supported. This prism feature is also included by default.

Example

    <!-- Navbar markup -->
    <div class="navbar navbar-inverse">
    	<div class="navbar-header">
    		<a href="index.html" class="navbar-brand">
    			<img src="assets/images/logo_light.png" alt="Logo">
    		</a>
    	</div>

    	<div class="navbar-collapse collapse" id="navbar-mobile">
    		<ul class="nav navbar-nav">
    			<li>...</li>
    			<li class="dropdown">...</li>
    		</ul>

    		<div class="navbar-right">
    			<ul class="nav navbar-nav navbar-left">
    				<li>...</li>
    				<li class="dropdown">...</li>
    			</ul>
    		</div>
    	</div>
    </div>
    <!-- /navbar markup -->
