The recommended way to mark up a code block (both for semantics and for Prism) is a <pre> element with a element <code> inside, like so:

Code:

                                                
                                                    <pre>
                                                        <code class="language-css">
                                                            p {
                                                                color: #1abc9c
                                                            }
                                                        </code>
                                                    </pre>
                                                
                                            

Output:

p {
    color: #1abc9c
}

Use the following code to use HTML syntax highlighter.

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. Add class line-numbers to your desired <pre> and line-numbers plugin will take care.

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

Usage:

                                                
                                                    <pre class="line-numbers">
                                                        <code class="language-css">
                                                            p {
                                                                color: red;
                                                            }

                                                        </code>
                                                    </pre>
                                                
                                            

Example:

                                                
                                                    (function() {
                                                        if (typeof self==='undefined' ||!self.Prism ||!self.document){return}});

Highlights specific lines and/or line ranges.

You specify the lines to be highlighted through the data-line attribute on the <pre>element,in the following simple format:

1. A single number refers to the line with that number
2. Ranges are denoted by two numbers,separated with a hyphen(-)
3. Multiple line numbers or ranges are separated by commas.
4. Whitespace is allowed anywhere and will be stripped off.

Usage:

<pre data-line="2,4, 8-10"><code class="language-css">p{color:red}</code></pre>

Example:

pre.line-numbers{position:relative;padding-left:3.8em;counter-reset:linenumber}pre.line-numbers>code{position:relative}.line-numbers .line-numbers-rows{position:absolute;pointer-events:none;top:0;font-size:100%;left:-3.8em;width:3em;letter-spacing:-1px;border-right:1px solid #999;-webkit-user-select:none;-moz-user-select:none;-ms-user-select:none;user-select:none}
