General ⇒ Numbering Issue in Cross-Referencing a Definition Block

[ranaya123]

I have some definition blocks written in my Latex code. These blocks give a nice graphical view to my definitions and here's how the code looks like:

In preamb:

Code: Select all

\newtcbtheorem[number within=section]{definition}{Definition}
    {
    	theorem style = plain apart, enhanced, frame hidden, breakable,
    	boxrule=2mm,titlerule=0mm,toptitle=1mm,bottomtitle=1mm,
    	fonttitle=\bfseries\large, fontupper=\normalsize,
    	coltitle=black!60!PinkNude, colbacktitle=white!70!PinkNude,
    	colback=white!80!PinkNude
 }{def}

And here's an example definition block:

Code: Select all

 \begin{definition}{}{}\label{def:2_1}
  \begin{itemize}[leftmargin=*]
    	\item The \textit{inertial delay} is the time delay consumed by an electrical signal to activate a single MOSFET transistor.
    	\vspace*{1mm}
        \item The \textit{inertial delay} is the time delay consumed by an electrical signal to activate a single MOSFET transistor.
  \end{itemize}
  \end{definition}

And the cross reference:

we define the inertial delay ($\tau$\textsubscript{D}) of a MOSFET in the definition block \ref{def:2_1}.

However, this does not produce the correct cross referencing as shown below:

Can anybody shed a light on to what's happening here? Why the cross-referencing is wrong here?

Thanks and Regards

I found the solution by myself. The trick is to use referencing as follows:

So the second argument (within the bracket) of the definition block is therefore the cross referencing! I didn't know that.

Code: Select all

\begin{definition}{}{2_1} 
\ref{def:2_1}
