编译警告 - “负标签宽度。这没有多大意义，”

我在下面的文档中遇到了编译错误。我制作了一个我喜欢用于笔记的大纲模板，但收到了一个编译警告，其中有一些“建议”。这些是什么意思？我还收到了 fancyhdr 警告。

\begin{enumerate}
\item (Converse, Inverse, Contrapositive) are there any others? Would you call these operators? Is this similar to typecasting in programming? 
\item Do these apply to quantified statements in the same way they apply to conditional statements? 
\item \[

\text{``if p then q''}\\
\text{``p and not q''}

\item p but q $\equiv$ p and q
\item Why is a biconditional statement different than $\land$
\item Quantified statements are made up of two items
\subitem Predicates $\rightarrow$ make up the domain
\subitem Quantifiers $\rightarrow$ identify items in the domain
\item (p $\rightarrow$ q) $\land$ ($\therefore (\sim$ p)) $\leftarrow$ can I use this notation? 
\item An argument is valid if and only if the premises is true and the conclusion is true? 
\item An argument is invalid if and only if the premises is false and the conclusion is true?

关系\leftmargin + \itemindent = \labelindent + \labelwidth + \labelsep必须满足。 和 为\leftmargin=0pt正值\labelsep，因此 为负值\labelwidth。

您可以使用 来解决它itemindent=!。

\begin{enumerate}[wide, labelwidth=!,itemindent=!,labelindent=0pt, leftmargin=0em, label=\arabic*, itemsep=1.2cm, parsep=0pt, font=\large\color{red}]

（顺便说一句，你应该增加\headheight）
