Syntax Highlighter for WordPress using Highlight.js.

  1. Click Plugins > Add New in the WordPress admin panel.
  2. Search for "wp-syntax-highlighter" and install.


The plugin comes bundled with all the themes provided by Highlight.js. Use the Theme dropdown to change the selected theme.

Additionally the plugin checks for a custom.css in your current theme's directory at {current_theme}/wp-syntax-highlighter/custom.css.

If this CSS file is present it will be added to the page automatically. You can override any builtin theme's styles in this manner.

To use a completely custom theme use the Custom option in Theme dropdown. Now only your current theme's custom.css will be used to style the code blocks.


Each language gets it's own shortcode. You can use this to add code blocks for that language into your posts.

For instance to add some PHP code into your post use,

foreach ($requirements as $requirement) {
  $result = array(
    'satisfied' => $requirement->check(),
    'requirement' => $requirement

  array_push($results, $result);

  if (!$result['satisfied']) {
    $success = false;

Compatibility with other Syntax Highlighters

The plugin is completely compatible with other syntax highlighters. It does not change the content of your existing posts. You can safely go back to use your previous syntax highlighter after trying out wp-syntax-highlighter.

Both Syntax Highlighter and GeSHi and supported by default. Prism based syntax highlighters will also work out of the box as they utilize the same markup as Highlight.js.

Requires: 3.5.0 or higher
Compatible up to: 3.9.15
