在复杂的标题页中定位日期很困难

我在网上找到了以下模板（经过一些搜索），基本上我的问题是如何将日期设置在靠近标题页下部的位置。

在此处输入图片描述

我用来获取上述输出的代码如下：

\documentclass[letterpaper]{article}

\usepackage{babel,titling,float,tikz,amsmath,cancel,amsbsy,amsfonts,graphicx,adjustbox,epigraph}

\renewcommand\epigraphflush{flushright}
\renewcommand\epigraphsize{\normalsize}
\setlength\epigraphwidth{0.7\textwidth}

\definecolor{titlepagecolor}{cmyk}{1,.60,0,.40}

\DeclareFixedFont{\titlefont}{T1}{ppl}{b}{it}{0.5in}

\makeatletter                       
\def\printauthor{%                  
    {\large \@author}}              
\makeatother
\author{%

    }

答案1

（1）加载包geometry。

（2）在标题页之前添加\newgeometry{bottom=0.5cm}以扩展页面的（默认）底部边距。

（3）在日期前添加垂直空格，

（4）使用\restoregeometry恢复文档的边距。

答案2

一个分析，没有完整的解决方案：

  • 只需要几个包就可以呈现这个标题页
  • 包括\usepackage[showframe]{geometry}查看当前设置
  • 必须手动设置日期，作为一种解决方法
  • \end{document}在复制的源中缺失
  • 休息似乎很好：一种方法是这样做

因此，从绘制的框架来看，日期已经“在底部”。

建议：

  • 将日期移至页脚
  • 或者根据需要删除页脚并扩展布局，即textheight
  • 有关详细信息，请参阅文档ctan geometry（https://ctan.org/pkg/geometry）
