Latex notes

The overall structure

latex The simple principle of is ：latex Code ---> pdf finished product

take latex The code becomes pdf finished product ,latex What is the code format of ？ What does each part look like ？

To solve these two problems, yes latex Have a simple understanding , I summarize from the following two aspects latex

latex part

stay latex The code you write usually contains two parts , The relationship is as follows ：

 

 1. Words and charts have different forms

 2. The command area and the content area have different characteristics

These two different features make it difficult for the compiler to distinguish , To solve this problem , We need to realize the right Environmental Science To illustrate

1. Name of the environment --- Tell the compiler what method to use

2.  Environment start and end time （ It can also be understood as a region ）--- Tell the compiler when to start and stop the current method

notes ： Because the translator needs different methods when dealing with charts and words , The area used to tell the compiler is called environment .

Local details

% This is the command area 
\documentclass[12pt]{proc}
\usepackage[utf-8]{ctex}
\usepackage{xeCJK}
\usepackage{enumitem}

% This is the content area 
\begin{document}
 This is an enumeration ( Ordered list )
\begin{enumerate}
        \item documentclass
        \item usepackage
        \item begin $\backslash$ \{ document \}
\end{enumerate}
\end{document}

In this case , Command area There are two command

1.documentclass Document class

2.usepackage Reference macro package  

Content area Yes Two environments ：

1.document Document environment

\begin Tell compiler So let's start here

{document} Tell compiler Here is the document environment

\end{document} The environment is over

2.enumerate Enumerate environments

\begin Tell compiler So let's start here

{enumerate} Tell compiler Here is the document environment Is it necessary to change the way

\end{enumerate} The environment is over

The compilation results are as follows ：

  The black arrow in the figure refers to the area where the distance can be adjusted to achieve different effects

One of the items in the unordered list ：

  The blue arrow in the figure is where the distance can be adjusted

See ：(25 Bar message ) LaTex Introduction to common commands _zdm_0301 The blog of -CSDN Blog _latex Common commands

latex The list and text cannot be aligned ：   

  Through the observation of the table , The list symbol is not aligned with the above text , Why is that ？ How should we adjust ？

  Obviously , There are two ways to align list sequence and text

1. Adjust the distance of the text

2. Adjust the item list

Here we use the second way , Use list items [leftmargin = 38pt] Get the results

Reflection after getting ：

leftmargin It is relative to the leftmost paper line rather than the text on the previous line  

There is a default arrangement of text inside , There are margins, so the text and list cannot be aligned .
