Which file is responsible for the style of magento template path hints? How can I change the colour and font size of the hints that are highlighted by a red background?
The template path hints are generated in
Unfortunately the styles are hardcoded in the block class and cannot be changed via css.
Because this class is used as a parent class for others you cannot rewrite it in a classical way. You have to cop it in
app/code/local and do your modifications there.
You would have to iterate over all div's on the page that have the following CSS properties:
position:relative; border:1px dotted red; margin:6px 2px; padding:18px 2px 2px 2px;
You can see here :
vendor/magento/module-developer/Model/TemplateEngine/Decorator/DebugHints.php to change the styles.
If think the best way is to override these class in your theme but i don't know if i's possible.
I created an override to the class Mage_Core_Block_Template by creating a local folder under app > code > local > Mage > Core > Block. Now I can customize template hints.
