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-expand-lg navbar-dark">
<div class="navbar-brand">
<a href="index.html" class="d-inline-block">
<img src="assets/images/logo.png" alt="Limitless">
</a>
</div>
<div class="navbar-collapse collapse" id="navbar-mobile">
<ul class="navbar-nav mr-lg-auto">
<li class="navbar-nav-link">...</li>
<li class="navbar-nav-link dropdown">...</li>
</ul>
<ul class="navbar-nav">
<li class="navbar-nav-link">...</li>
<li class="navbar-nav-link dropdown">...</li>
</ul>

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.

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-expand-lg navbar-dark">
<div class="navbar-brand">
<a href="index.html" class="d-inline-block">
<img src="assets/images/logo.png" alt="Limitless">
</a>
</div>
<div class="navbar-collapse collapse" id="navbar-mobile">
<ul class="navbar-nav mr-lg-auto">
<li class="navbar-nav-link">...</li>
<li class="navbar-nav-link dropdown">...</li>
</ul>
<ul class="navbar-nav">
<li class="navbar-nav-link">...</li>
<li class="navbar-nav-link dropdown">...</li>
</ul>
</div>

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.
