枚举列表 - 条目以斜体显示

Question 1

渴望评论：

您提供的代码不完整，并且有很多错误（请参阅我在问题下方的评论）。因此，我们无法重现您的问题。因此，我恳请您更正提供的代码以完成小文档，从而重现您的问题。在此，请考虑我在问题下方的评论。
不要用\newline或来结束列表中的项目\\。它们只会使列表格式变得混乱。
不要在section标题内格式化部分样式。
对于链接，您需要使用用于超引用的包之一：url，或其扩展xurl或hyperref（˙url也包含）。
目前还不清楚您想要什么样的列表布局。下面在 MWE 中使用默认设置。如果您想更改它，软件包enumitem提供了许多可能性。例如，看看如果您使用开始列表会发生什么\begin{enumerate}[leftmargin=*]。

首先看看以下 MWE（最小工作示例）是否能提供您想要获得的内容：

\documentclass{article}

\usepackage{xcolor}
\usepackage{enumitem}
\usepackage{xurl}

Question 2

作为附录Zarko 的回答：

如果我拿来你的代码，添加\begin{document}和\end{document}并尝试编译它，正如预期的那样，我会收到多条错误消息。一旦您的编译过程导致错误消息，请不要查看输出，而是先修复它们。这一点尤其重要，因为 TeX 只会在发生错误后尝试恢复足够的文件以进行语法检查，而不会在发生错误后尝试生成合理的输出。因此，即使您得到的东西乍一看像 pdf 文件，它仍然可能存在问题。

点击带有红色矩形框和数字的按钮，可以查看错误消息。只要有红色矩形框，就会出现错误消息。

我们来看看错误信息：

! Missing $ inserted. l.25 ...them: https://www.math.uh.edu/~torok/math_

由于 url 包含，因此您会收到此错误消息_。由于您无法_在普通文本中使用，LaTeX 假设您实际上想要使用数学模式。（_在那里，您可以使用来表示下标，例如 $x_{y}$ ）由于您在这种情况下不想使用任何数学运算，但想要显示 url，请加载包xurl并将 url 放在\url命令内。对文档中的所有其他 url 重复此操作。

完成上述更改后，LaTeX 现在抱怨缺少\end{enumerate}，所以让我们在之前添加此行\end{document}。

添加此行后，我们仍然收到错误消息：

 Something's wrong--perhaps a missing \item.

这是因为 latex 期望输入枚举列表的项目采用以下通用格式：

\begin{enumerate}
\item text that belongs to the first item
\item text that belongs to the second item
\end{enumerate}

将此一般方案与您的代码进行比较，发现您从未使用过该\item命令。为了更正您enumerate环境中的语法，请\item在每个命令之前放置\textbf...并删除所有出现的\\ \\和，\newline因为这里不需要它们。

完成所有这些更改后，我们最终得到了一个代码，该代码最终编译时没有任何错误消息：

\documentclass{article}
\usepackage{fullpage}
%\usepackage{graphicx} % not related to this example
%\usepackage{xcolor} % not related to this example
%\usepackage{fancyhdr} % not related to this example

最后，让我们看一下输出。你在所有项目中使用，并在问题中\textbf提到尝试过，这让我猜想，你实际上可能对未编号的描述式列表感兴趣。如果是这种情况，你可以使用代替和等代替。如果你还希望更改网址的字体以匹配通常的文本字体，你可以添加到序言中：itemizedescriptionenumerate\item[CTAN (Comprehensive TeX Archive Network)]\item \textbf{CTAN (Comprehensive TeX Archive Network)}\urlstyle{same}

如果您希望 URL 中的换行符仅出现在特定位置（例如 a.或 a ）\，则可以使用url包而不是xurl。如果您想要超链接，请改用hyperref包。（前面提到的\url和\urlstyle{same}命令适用于所有三个包。）

如果您想进一步自定义列表的外观，例如，第二行和后续行的缩进\item、相邻项目之间的垂直空白或粗体和后续文本之间的空格，请查看enumitem包及其众多选项。
