Tikz fancytitle 中的自动换行（换行）或手动换行

Question

对于 Tikz Fancytitle，我该如何做：

1. 获取自动换行，或
2. 如果 1. 不可行，请添加手动换行符（例如，使用 \\）

我在这个例子中使用了嵌套的小页面，但问题也适用于外层小页面上的 Tikz 框上的标题！

谢谢！

如果不在\href节点内使用这些宏，这将阻止换行，您可以将该align选项与手动换行一起使用，\\如下所示（我删除了不必要的包并优化了包的顺序）：

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[landscape]{geometry}
\usepackage{multicol}
\usepackage{tikz}

\advance\topmargin-.8in
\advance\textheight3in
\advance\textwidth3in
\advance\paperheight1.5in 
\advance\oddsidemargin-1.5in
\advance\evensidemargin-1.5in
\parindent0pt
\parskip2pt

\usepackage{fourier}
\usepackage{hyperref}

\begin{document}

\begin{center}{\huge{\textbf{Notes}}}
\end{center}
\begin{multicols*}{3}

\tikzset{mybox/.style={draw=black, fill=white, very thick,
    rectangle, rounded corners, inner sep=10pt, inner ysep=10pt},
        fancytitle/.style={fill=black, text=white, font=\bfseries}
    }

%------------ Title ---------------
\begin{tikzpicture}
\node [mybox] (box){%
    \small
    \begin{minipage}{0.3\textwidth}
    
    %------------ Title ---------------
    \begin{tikzpicture}
    \node [mybox] (box){%
        \small
        \begin{minipage}{0.3\textwidth}
        \end{minipage}
    };
    \node[fancytitle, right=10pt, align=left] at (box.north west) {This is a really long title. With a second sentence. \\ And another sentence. And one more.};
    \end{tikzpicture}
    
    \end{minipage}
};
\node[fancytitle, right=10pt] at (box.north west) {Box 1};
\end{tikzpicture}

\end{multicols*}
\end{document}

您还可以使用选项text width（text width=8cm例如）进行自动换行，但无论内部文本的长度如何，节点始终具有相同的宽度。
