 #### Disable C++ exceptions
 
--D<b>nsel\_CONFIG\_NO\_EXCEPTIONS</b>=0
+-D<b>nsel\_CONFIG\_NO\_EXCEPTIONS</b>=0  
 Define this to 1 if you want to compile without exceptions. If not defined, the header tries and detect if exceptions have been disabled (e.g. via `-fno-exceptions` or `/kernel`). Default determined in header.
 
 #### Enable SEH exceptions
 
--D<b>nsel\_CONFIG\_NO\_EXCEPTIONS\_SEH</b>=0
+-D<b>nsel\_CONFIG\_NO\_EXCEPTIONS\_SEH</b>=0  
 Define this to 1 or 0 to control the use of SEH when C++ exceptions are disabled (see above). If not defined, the header tries and detect if SEH is available if C++ exceptions have been disabled (e.g. via `-fno-exceptions` or `/kernel`). Default determined in header.
 
 #### Disable \[\[nodiscard\]\]
 
--D<b>nsel\_CONFIG\_NO\_NODISCARD</b>=0
+-D<b>nsel\_CONFIG\_NO\_NODISCARD</b>=0  
 Define this to 1 if you want to compile without \[\[nodiscard\]\]. Note that the default of marking `class expected` with \[\[nodiscard\]\] is not part of the C++23 standard. The rationale to use \[\[nodiscard\]\] is that unnoticed discarded expected error values may break the error handling flow.
