最近我看到了一本关于如何使用的手册词汇表，源代码第 14 页有一个脚注：
- 打开源代码
- 从服务器下载
- 通过下载完成的 pdf 文件，我想在我的代码中实现相同的功能，请问您能帮助我吗？
大致看起来应该是这样的：
如果没有所需的脚注，它看起来像这样：

提前谢谢您，干杯！
答案1
嗯，从外观上看，Talbot 使用tcolorbox、graphicx和hyperref包来创建您展示的示例中的布局。
tcolorbox创建带有 PDF 图标的框和标题。该graphicx包用于将图标插入href语句：`href[options]{URL}{text/icon}。
我玩了一下，从网上下载了一些相关的图标，并创建了这个小型 MWE，它展示了与您的示例相同的想法：
\documentclass[a4paper,11pt]{article}
\usepackage[many]{tcolorbox}
\usepackage{graphicx}
\usepackage{hyperref}
\begin{document}
\begin{tcolorbox}[rounded corners,arc=8pt,size=fbox,boxsep=6pt,enhanced,attach boxed title to top right={yshift=-3mm,xshift=-3mm},title={\href{url}{\includegraphics*[width=4mm]{pdf_icon.png}}}]
\hfill \href{ulr2}{\includegraphics*[width=3mm]{clip_icon.png}}
\hspace{1mm} \href{ulr2}{\includegraphics*[width=3mm]{down_icon.png}}
\vspace{-18pt}
\begin{verbatim}
vector<int> divisors[n + 1];
for (int a = 1; a <= n; a++)
for (int b = a; b <= n; b += a) divisors[b].push_back(a);
\end{verbatim}
\end{tcolorbox}
\end{document}
输出如下所示：
