wicked-pdf

问题 I need to convert a .haml view to .pdf using wicked_pdf (or another), the problem is ... I use flexboxgrid (try BootstrapGrid before but it does not work), the columns (.col-xs- *) do not work as it.

However, I don't want this for my first page , because the header is only used on page 2 and above. How do I achieve this? Attempts For contents in the first page, via CSS I tried: position: absolute; top: -20; Which results in the content being "clipped" by the
