Layout Problem PDF Export

[Alonso Mata]

When exporting a space the size of the titles of the page tree is not as desired. The problem is that when trying to implement code to make them bigger using the class or id of these elements in HTML. However, it does not apply after many different approaches. I would like to know what class or type is confluence using when exporting this elements to be able to personalize them.

This is how it is exported:

Hi @Alonso Mata welcome to the community.  I know Atlassian mentioned in their latest release notes that they are rolling out fixes for Exporting to PDFs.  That article is here: Cloud Changes 

I don't know how to tell if they've been rolled out to your Confluence instance yet or not.  I couldn't find a specific Jira ticket for this issue that was resolved. You could open a support ticket with Atlassian (support.atlassian.com then click contact link in upper right) and see if this was one of the things addressed in this update.  

I'm pretty sure you can't configure how the export works for that macro, but I could be wrong.

Hope that helps.
