Including “boxes inside boxes” in baposter

Question

I have divided my poster into \headerbox correctly.

I would like to modify the following example because in the results section I would like to make subdivisions or boxes in order to show different results. By the way, I have chosen this template but if you think it would be better to use a different one please say it. Any ideas?

Answer 1

You could always use plain old \section* to make subheadings. If that is too plain, use for example tcolorbox and customize the box to your liking. For the code below, I just copied an example from the manual and changed the colors and text a bit.

Please add a comment if you have any more specific guidelines.

(I removed most of your preamble, because I don't really think it was relevant to the question.)

Columns

If you want content side by side there are several options. tcolorboxes can be placed side by side, so that is one option. tcolorbox also has the raster library for setting up matrix-like structure. The example in the code below is copied directly from the manual, and merely to show what the package can do. I don't really have much experience with the package, so if it looks interesting I advise you to search this site for examples, and looking at the manual.

A more mundane setup would be to use the multicols environment from the multicol package. With this, the text will continue from the first to the second column. You can of course place images in here as well.

(This code, as the one above, is of course only intended to show a couple of examples.)
