类似这样的事？

\documentclass [a4paper,12pt]{report}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{comicsans}
\usepackage{geometry}
\usepackage[x11names]{xcolor}
\colorlet{rulecolor}{LightSteelBlue3}
\newcommand\colorhrule{\makebox[0pt]{\color{rulecolor}\rule{0.95\paperwidth}{0.6pt}}}
\usepackage{titlesec}
\newpagestyle{title}{%
\sethead{}{}{}
\setfoot{}{}{\raggedleft\rlap{\quad\thepage}}
}%

\begin{document}

\newgeometry{showframe, nomarginpar, nohead, footskip = 6pt, hmargin=25mm, top=15mm, bottom=20mm}
