place a minipage on the top of a page

Question

I need to place a minipage on the top of a page. I use the t option, but seems not working.

\usepackage{abbrevs}
\usepackage{adjustbox}
\usepackage{floatrow}
\usepackage{graphicx}
\usepackage{latexsym}
\usepackage{paralist}
\usepackage{pgfplots, pgfplotstable}
\usepackage{subfig}
\usepackage{tikz}
\usepackage{times}

\begin{minipage}[t]{0.8\textwidth}
      \begin{minipage}[b]{0.4\textwidth}
        \centering
        \adjustbox{width=0.7\textwidth} {
          \begin{tikzpicture}[text centered, nodes = {draw, minimum size = 22mm}]
            \matrix at (0, 0)
                    {
                      \node {$ 1 $}; & \node {$ 1 $}; \\
                      \node {$ *1 $}; & \node {$ *1 $}; \\
                    };
          \end{tikzpicture}
        }
        \captionof{figure}{fig 1.}
      \end{minipage}%
    \hfill
      \begin{minipage}[b]{0.46\textwidth}
        \centering
        \adjustbox{width=1.2\textwidth} {
          \begin{tikzpicture}[text centered, nodes = {draw, minimum size = 12mm}]
            \matrix at (0, 0)
                    {
                      \node {$ 2 $}; & \node {$ \forall $}; \\
                      \node {$ 2 $}; & \node {$ 2 $}; \\
                    };
          \end{tikzpicture}
        }
        \captionof{figure}{fig 2.}
      \end{minipage}
    \end{minipage}

Answer 1

The [t] option does not represent where the minipage will be placed on the page, but actually represents the internal alignment of the material.

If you want the minipage to be put at the top of a page, you can put it into a floating environment- either a figure or table (or you could even create your own if you wanted to).

So, the following would get you closer to what you want

\begin{figure}[!t]
    \begin{minipage}{.3\textwidth}
    ...
    \end{minipage}
\end{figure}

Of course, now that your minipage is floating, it may not be in the order that you desire with respect to your other content. If you don't want it to float, then you might also look into \clearpage or \newpage
