+
+The font size for the content of a box with fixed width and fixed height
+can be adjusted automatically. This is called the \emph{fitbox capture mode}.
+Note that the fit control algorithm
+constructs a series of versions for the box and selects the 'best'.
+Therefore, the compilation time is quite longer than for a normal box.
+The algorithm will fail, if a different selected font size does not change the
+overall size of the box content.
+The \refCom{tcboxfit} macro uses this algorithm by default.
+
+\medskip
+\begin{marker}
+  The fit control keys are only applicable to unbreakable boxes without
+  a lower part.
+  The box content should not change counters.

+\enlargethispage*{5mm}
+\begin{docTcbKey}{fit}{}{style, initially unset}
+  Sets the \refKey{/tcb/capture} mode to |fitbox|, i.\,e.\ enables the
+  font size adjustment algorithm. Thereby, a \refEnv{tcolorbox} acts
+  like \refCom{tcboxfit} where the given \meta{box content} is fitted to
+  the width and height of the box. Therefore, the box has to have a fixed height.
+  If no fixed height is given, a square box is constructed.
+  The font dimension \docAuxCommand{tcbfitdim} can also be used to adjust
+  the margins of the box since a box with a tiny font may not need large
+  margins. The number of constructed boxes is saved to the macro \docAuxCommand{tcbfitsteps}
+  for analysis.

+\subsection{Border Line Option Keys}\label{subsec:borderline}
+The following border line options are applicable for most skins which
+use |tikzpicture| as \refKey{/tcb/graphical environment}.
+Therefore, the skin \refSkin{standard} does not support these border lines,
+but most other skins, e.\,g.\ \refSkin{enhanced}.
+
+The border lines are independent from the normal |tcolorbox| rules.
+They may be used with or without the \refKey{/tcb/segmentation engine}.
+
+The border lines are stackable, i.\,e.\ several different border lines can be
+used on the same |tcolorbox|. They are drawn \emph{after} the box frame and box
+interior and \emph{before} overlays or watermarks.
+
+\begin{marker}
+Technically, the normal |tcolorbox| rules result from a TikZ \emph{filling}
+process. The border lines are created by a TikZ \emph{drawing} process.
+This can be used to apply different effects.
+\end{marker}
+
+
+\begin{docTcbKey}{borderline}{=\marg{width}\marg{offset}\marg{options}}{no default, initially unset}
+  Adds a new border line to the stack of border lines.
+  This border line is drawn with the given \meta{width} and gets a
+  \meta{offset} computed from the frame outline. A positive \meta{offset} value
+  moves the borderline inside the |tcolorbox| and a negative \meta{offset} value
+  moves it outside without changing the bounding box.\\
+  The border line is drawn along a TikZ path with the given TikZ \meta{options}.
+  Note that the TikZ |line width| option should not be used here.\\
+  The border lines adapt to the rounded corners of the |tcolorbox|. An inside border
+  line will switch to sharp corners if necessary, an outside border line will
+  always be rounded if not set to |sharp corners|.
+\begin{dispExample}
+\begin{tcolorbox}[enhanced,title=Rounded corners,fonttitle=\bfseries,boxsep=5pt,

+Therefore, the skin \refSkin{standard} does not support these shadows,
+but most other skins, e.\,g.\ \refSkin{enhanced}.

+
+
+\begin{docTcbKey}{shadow}{=\marg{xshift}\marg{yshift}\marg{offset}\marg{options}}{no default}
+  Adds a new shadow to the stack of shadows.
+  This shadow is follows the outline of the |tcolorbox| but is shifted by
+  \meta{xshift} and \meta{yshift}. The \meta{offset} value is a distance value
+  from the frame outline.  A positive \meta{offset} value shrinks the shadow
+  and a negative \meta{offset} value enlarges the shadow.
+  The shadow is filled along a TikZ path with the given TikZ \meta{options}.\\
+  The shadows adapt to the rounded corners of the |tcolorbox|. An shrinked shadow
+  will switch to sharp corners if necessary, an enlarged shadow may become
+  more rounded depending on several factors.
