[Tex/LaTex] \vspace after \vfill ignored

Question

\vfill
Text first line
\vspace{1cm}
Text second line
\cleardoublepage

The \vspace is unfortunately ignored by LaTeX: The resulting document has no vertical space added between the two lines. Why is that?

Answer 1

You need to add a) something (e.g., an empty box) before \vfill (assuming \vfill is at the top of the page) b) a paragraph between the first and second line.

\documentclass{article}
\begin{document}
\null\vfill
Text first line

\vspace{1cm}
Text second line
\end{document}
