Modifying Joomdle look and feel
You can change how Joomdle views and modules look like by creating template overrides. Joomla documentation for this feature is at: https://docs.joomla.org/How_to_override_the_output_from_the_Joomla!_core
For example, if you want to change how the Joomdle course list view looks like, you would start by creating new folders:
TEMPLATE_NAME/html/com_joomdle
TEMPLATE_NAME/html/com_joomdle/joomdle
Then, copy the file /components/com_joomdle/views/joomdle/tmpl/default.php to TEMPLATE_NAME/html/com_joomdle/joomdle and modify its layout to meet your needs.
In the Joomdle demo, you can see that some views look different from stock Joomdle, as we created some template overrides to make the views look more integrated with the template we are using.
