用latex的ACM模板写论文如何简单粗暴去除页眉页脚以及Reference

简单粗暴如下：
Step 1、latex最开始补充：

\documentclass[acmsmall]{acmart}
\settopmatter{printacmref=false} % Removes citation information below abstract
\renewcommand\footnotetextcopyrightpermission[1]{} % removes footnote with conference information in first column
%\pagestyle{plain} % removes running headers

Step 2、在acmart.cls里找到\pagestyle并将standardpagestyle替换成empty

%\pagestyle{standardpagestyle}
\pagestyle{empty}

Step 3、在acmart.cls里搜索Publication date，并将其大括号内的删除：

 \fancyfoot[RO,LE]{\footnotesize \@journalNameShort, Vol. \@acmVolume, No.
        \@acmNumber, Article \@acmArticle.  Publication date: \@acmPubDate.}%

⬇

 \fancyfoot[RO,LE]{}%
