Why does the formatting of my generated document change when I use PDF Export's header or footer?

[Italo Ebel]

This is the PDF generated without changing the stylesheet:

If you add a header ("my header"), the formatting of the PDF will change.

Stylesheet with header added:

PDF generated after this change:

Why have some elements such as image size, caption, margins been changed?

*Perhaps Confluence is using different versions of the Export function for each document generated

Hi @Italo Ebel 

Did you apply the header as html or css or just plain text?

Plain text won't work and will impact your export, I believe.

Check the following KB docs:

• customize-exports-to-pdf 
• advanced-pdf-export-customizations

Hello @Marc - Devoteam

Thank you for reply.

I've seen this documentation before. In the example given I used plain text, but even when using only html and css in the header and stylesheet some structures are damaged in the PDF.

For some reason the image captions aren't appearing after the changes to the Look and feel.

There is probably some custom Confluence command responsible for modifying the captions, but I can't find it.
