How to export PDF in 2 column layout?

[Fabricio Mabillot]

If anyone has any ideas

In advance, thank you.
I'm trying to export my Confluence pages as PDF through Export Space.
I tried adding CSS codes like:

column-count: 2;
column-gap: 20px;
column-rule: 1px dotted rgb(185, 185, 185);

I entered them as:

@page, .view , .content , .body, .wiki-content, .contentLayout2

none of them worked!!
I created a code that helps a lot to create a complete layout, I'll leave it below to help others.

I realized that there are many problems related to this.

Thank anyway.
