# How to use

Obviously, this is supposed to work only for code blocks (`<pre><code>`) and not for inline code.

Add the `line-numbers` class to your desired `<pre>` or any of its ancestors, and the Line Numbers plugin will take care of the rest. To give all code blocks line numbers, add the `line-numbers` class to the `<body>` of the page. This is part of a general activation mechanism where adding the `line-numbers` (or `no-line-numbers`) class to any element will enable (or disable) the Line Numbers plugin for all code blocks in that element.
Example:

    <body class="line-numbers"> <!-- enabled for the whole page -->

    	<!-- with line numbers -->
    	<pre><code>...</code></pre>
    	<!-- disabled for a specific element - without line numbers -->
    	<pre class="no-line-numbers"><code>...</code></pre>

    	<div class="no-line-numbers"> <!-- disabled for this subtree -->

    		<!-- without line numbers -->
    		<pre><code>...</code></pre>
    		<!-- enabled for a specific element - with line numbers -->
    		<pre class="line-numbers"><code>...</code></pre>

    	</div>
    </body>

Optional: You can specify the `data-start` (Number) attribute on the `<pre>` element. It will shift the line counter.

Optional: To support multiline line numbers using soft wrap, apply the CSS `white-space: pre-line;` or `white-space: pre-wrap;` to your desired `<pre>`.

# Examples

## JavaScript

## CSS

Please note that this `<pre>` does not have the `line-numbers` class but its parent does.

## HTML

Please note the `data-start="-5"` in the code below.

## Unknown languages

    This raw text
    is not highlighted
    but it still has
    line numbers

## Soft wrap support

Please note the `style="white-space:pre-wrap;"` in the code below.
