Frequently Asked Questions

Which programming languages are supported?

I don’t like the style and theme colors of this plugin. How to change the colors?

Edit the file highlighter.css to change the colors. See the documentation of CSS and class details at Google Code Prettify

Will this highlighter make my webpage slow?

SmartAss Highlighter uses two files in output- highlighter.js and highlighter.css. These two files have total size of 17KB but If you web server supports compression then the reduced load will be of 7KB. However, If your server does not support compression or you dont have control over it, please edit line 15-18 of plugin page “SmartAss-Highlighter.php” to:

$highlight_js = "";
$highlight_style = "";
#$highlight_js = plugins_url('/highlighter.js', __FILE__);
#$highlight_style = plugins_url('/highlighter.css', __FILE__);

Note : By altering the above code, You are actually changing the path of the libraries to pre-hosted files in this server. You can change the path to any valid URL without affecting the functionality of the plugin.

What is different about this highlighter?

  • It uses a shortcode to trigger, so user can control highlighting from post to post.
  • The extra code/libraries are added in footer, so that you page is loaded first and highlighting is done later asynchronously
  • No option menu
