# How can I get rid of vertical space before /par

I've been trying to align my document precisely. I've come across a weird issue. What i'm trying to achieve is: 1) I want to have a top page header - this is drawn with tikz 2) I want to be able to precisely set the distance to the next entity(text or table) 3) So i've started with reducing the distance so i have clean start.

BUT im unable to remove the space before first \par:

\setlength{\parindent}{0em}
\setlength{\parskip}{0.0em}
\setlength{\topskip}{0.0em}
\setlength{\parsep}{0.0em}
\setlength{\partopsep}{0.0em}
\setlength{\topsep}{0.0em}
\def\arraystretch{0}%
\setlength\tabcolsep{0pt}
\begin{document}
\par
Why is there space above me?
\par
...


This is rendered as following(please note that i have dark background in editor):

I've tried all of the settings i could find that apply to \par spacing, but im not sure what is the issue.

This is how i draw the header:

\newcommand{\cvHeader}[3]{
%First thing to do, Set the keys
%from the single parameter input
\setkeys[CV]{top}{#1}
\noindent
\begin{tikzpicture}
\color{\cvBgColor}
\filldraw
(0,0) rectangle (\paperwidth,\cvHeight);
\draw node[color=\cvTextColor,anchor=west] at (\cvTextIndent,\cvHeight/2) {#2};
\draw node[color=\cvTextColor,anchor=east] at (\paperwidth - \cvTextIndent,\cvHeight/2) {#3};
\end{tikzpicture}
}


Weird thing is that the next \par does not have any space before it, which would maybe point to the drawing - but i've also checked the boxes there.

Only way how I managed to overcome this is by setting \vspace{-0.4cm} but that is not a robust solution.

Any help is highly appreciated!!

It is not vertical space, it is a horizontal line of a paragraph with the space characters from your source, I commented them out with %%%space

\documentclass{article}
\usepackage{tikz}

\setlength{\parindent}{0em}
\setlength{\parskip}{0.0em}
\setlength{\topskip}{0.0em}
\setlength{\parsep}{0.0em}
\setlength{\partopsep}{0.0em}
\setlength{\topsep}{0.0em}
\def\arraystretch{0}%
\setlength\tabcolsep{0pt}

\def\cvBgColor{red}
\def\cvTextColor{blue}
\def\cvHeight{30pt}
\def\cvTextIndent{0pt}
%First thing to do, Set the keys
%from the single parameter input
%  \setkeys[CV]{top}{#1}
\noindent
\begin{tikzpicture}
\color{\cvBgColor}%%%space
\filldraw
(0,0) rectangle (\paperwidth,\cvHeight);
\draw node[color=\cvTextColor,anchor=west] at (\cvTextIndent,\cvHeight/2) {#2};
\draw node[color=\cvTextColor,anchor=east] at (\paperwidth - \cvTextIndent,\cvHeight/2) {#3};
\end{tikzpicture}%%%% space
}
\begin{document}

The heading line is overfull as it is \paperwidth wide but starting at the edge of the text block not the edge of the page, you might want to add a negative space to account for the left margin.
