paragraphsspacing
I have the below code :
\documentclass[12pt]{book}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\lipsum[1]
\end{document}
I would like to be able to define the margins of new paragraphs. I am a web guy so I will give an example with CSS for what I am trying to do :
p{margin-top: 10px;margin-bottom: 5px;}
how can I apply that?
No, \includegraphics does not add any margins by itself. You seem to use it either inside a figure or center environment which both add margins.
The distance between floats like figure and table is defined by the lengths \textfloatsep and for figure* in twocolumn documents by \dbltextfloatsep.
You can set these to zero to remove all separation.
Should you use the center environment instead, replace it with \centerline{\includegraphics[..]{..}}.
You can also add and remove some vertical space before and after the \includegraphics using \vspace{<length>} where the length can be positive or negative.
The space above and below the listing can be set using aboveskip and belowskip. The default value is \medskipamount.
\documentclass{article}
\usepackage{tikz}
\usepackage{listings}
\begin{document}
\tikz \node[inner sep=1mm, text width=6cm, draw=green, line width=2pt, rounded corners]
{%
\lstinputlisting[basicstyle=\tiny\ttfamily, columns=fullflexible, breaklines=true,aboveskip=0pt,belowskip=0pt]{data.txt}
};
\end{document}

TeX has no notion of space before and after paragraphs, but only of space between paragraphs. This space is, by default, zero, but with a small degree of flexibility, in order to help filling up a page when flush bottoms are requested (as in the book class, not in article).
The relevant parameter is
\parskip: a declaration such astells TeX to space paragraph by 15pt, reducible to 13 or enlarged to 16. Such a spacing will disappear at page breaks.
However, many respected typographers frown upon paragraph spacing, that interrupts the flow of reading and spoils the uniformity of the page. While paragraph spacing may be considered for documents such as letters, it's really not recommended for longer texts.
Make a selection of books printed by good publishers and count how many of them use paragraph spacing: you'll find only a few, if any.
