[Tex/LaTex] Issue with mdframed package

mdframedtikz-pgf

mdframed package creates a beautiful box around the content. And it has the capability to break between pages as in the image below
enter image description here
second part

I have done the decoration of getting the concept 5 : algebraic identities on the box but when the box breaks on the page to carry some part of the content to the next page (as shown in the second image below) the beautiful header "Concept 5 : algebraic identities" blocks the content behind.

My questions are there ways by which we can leave some space post the header or just remove the header in the broken part on the next page.
Kindly help me.. apologies if something not clear.

the code to get the required frames is

Best Answer

In mdframe if you want to control the space left before and after the split of a frame across pages (the kind of trouble I was facing above) one can use the options splittopskip=1cm, splitbottomskip=1cm, in the \mdfdefinestyle part of the code above which is diplayed below.

\mdfdefinestyle{theoremstyle}{% 
outerlinewidth=1pt,
innerlinewidth=3pt,
roundcorner=5pt,
linecolor=black,
shadow=true,
splittopskip=1cm,         % THIS IS THE REQUIRED OPTION FOR SPACE ABOVE THE SPLIT ON THE SECOND PAGE
splitbottomskip=1cm,      % THIS IS THE REQUIRED OPTION FOR SPACE BELOW THE SPLIT ON THE FIRST PAGE 
tikzsetting={shading=axis,top color=gray!10},
innertopmargin=1.2\baselineskip,
skipabove={\dimexpr0.5\baselineskip+\topskip\relax},
needspace=3\baselineskip,
frametitlefont=\sffamily\bfseries,
settings={\global\stepcounter{theorem}},
}

[Tex/LaTex] Excursus environment using mdframed: Issue with page breaks

I uploaded version 1.5 and added an exampple of the excurs-environment. You can find the example in the file mdframed-example-texsx.pdf (Example 5).

The environment can be defined with the following settings:

\usetikzlibrary{calc,arrows}

Needed for the design (not mdframed related)

Define the style of the lines and the arrows (not mdframed related)

\tikzset{
   excursus arrow/.style={%
    line width=2pt,
    draw=gray!40,
    rounded corners=2ex,
   },
   excursus head/.style={
    fill=white,
    font=\bfseries\sffamily,
    text=gray!80,
    anchor=base west,
   },
}

Define the new environment with the new keys of version 1.5: singleextra, firstextra, middleextra and secondextra

\mdfdefinestyle{digressionarrows}{%
  singleextra={%
   \path let \p1=(P), \p2=(O) in (\x2,\y1) coordinate (Q);
   \path let \p1=(Q), \p2=(O) in (\x1,{(\y1-\y2)/2}) coordinate (M);
   \path [excursus arrow, round cap-to]
   ($(O)+(5em,0ex)$) -| (M) |- %
   ($(Q)+(12em,0ex)$) .. controls +(0:16em) and +(185:6em) .. %
   ++(23em,2ex);
   \node [excursus head] at ($(Q)+(2.5em,-0.75pt)$) {Digression};},
  firstextra={%
   \path let \p1=(P), \p2=(O) in (\x2,\y1) coordinate (Q);
   \path [excursus arrow,-to]
   (O) |- %
   ($(Q)+(12em,0ex)$) .. controls +(0:16em) and +(185:6em) .. %
    ++(23em,2ex);
   \node [excursus head] at ($(Q)+(2.5em,-2pt)$) {Digression};
  },
  secondextra={%
   \path let \p1=(P), \p2=(O) in (\x2,\y1) coordinate (Q);
   \path [excursus arrow,round cap-]
   ($(O)+(5em,0ex)$) -| (Q);
  },
  middleextra={%
   \path let \p1=(P), \p2=(O) in (\x2,\y1) coordinate (Q);
   \path [excursus arrow](O) -- (Q);
  },
  middlelinewidth=2.5em,middlelinecolor=white,
  hidealllines=true,topline=true,
  innertopmargin=0.5ex,
  innerbottommargin=2.5ex,
  innerrightmargin=2pt,
  innerleftmargin=2ex,
  skipabove=0.87\baselineskip,
  skipbelow=0.62\baselineskip,
}

Important are the lines:

  middlelinewidth=2.5em,middlelinecolor=white,
  hidealllines=true,topline=true,

First I removed all lines drawn by mdramed and add only the first line. The first line with line color white is needed. In this way mdframed knows the height of the excurs-lines and can calculate the correct splitting point.

With these settings you get:

[Tex/LaTex] How to define the default vertical distance between nodes

I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.

Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
