2

I like the nice yellow margins (top and bottom) and spacings from the yellow tcolorbox in "Subsection 2". Unfortunately I get this margins and spacing only directly after a \section or \subsection. Problems: a) Without a \section or \subsection in front of a tcolorbox the top margin is greater b) I lose the white spacing between two tcolorboxes in some cases, see my examples. Especially the grey tcolorboxes have a white spacing between, but yellow ones do not.

How to get the same nice margins and spacings in any case? Of course there is no problem with additional white spacings after/ before a headings like \section or \subsection to respect the headings.

For problem a), leave out the space before \subsubsection with: \RedeclareSectionCommand[beforeskip=0pt]{subsubsection}.

For problem b), comment out the line beforeafter skip balanced=0pt,. To avoid affecting the rest of your document, do it only before the subsections in your boxes and then restore the original value of the class.

I also added frame empty, to avoid the little frame rules still visible with boxrule=0pt.

  • \RedeclareSectionCommand[beforeskip=0pt]{subsubsection} seems to be a global redeclaration with effects to the other parts of my text. Is there a way to focus the redeclaration only to the content of the tcolorboxes? I do not want to miss the normal space before a subsubsection.

  • In general it should be better to save the actual value of beforeskip in a variable and then restore the value with the help of the variable. In my case I really use a subsection instead of a subsubsection and I do not know the default value to restore. How to save and restore the value of beforeskip?

  • possible bug in your renewed Code: please look at the number of the part "sub" in your code in several places.

  • I think \let\savedsubsubsection\subsection should be \let\savedsubsubsection\subsubsection. There is more than one error, even in your comment. Or maybe I didn´t understand the program code?

  • @Michael.H You're right, I copied-pasted what I did without reading, I'll correct
