Text put above figure but is meant to be below

Question

I wrote something like this

text
\begin{figure}
 ...
 ...
\end{figure}
\section{} or text (the problem shows up anyway)

but when I compile (with overleaf) all the text that is meant to be below the image is put above and I can't write anything. Also, if I add another line it works properly, like this

text
\begin{figure}
 ...
 ...
\end{figure}
not_useful_text
\section{} (or text, it's the same)

Answer 1

I believe that you need exact image placement, if yes, try with:

\usepackage{float}
\begin{document}
...
text
\begin{figure}[H]
 ...
 ...
\end{figure}
not_useful_text
\section{} (or text, it's the same)
...
\end{document}
