Usually LaTeX will wrap lines and pages automatically. Users can also use \\ or \newline to force a line break;
Use \newpage to force a page break. Under normal circumstances, LATEX will try to hyphenate evenly, so that the word spacing of each line is neatly distributed.
But sometimes we also need to explicitly indicate the hyphenation position. For example, the following example indicates that the word BASIC cannot be broken, but blar-blar-blar can be broken at -.
\hyphenation{BASIC blar-blar-blar}
LaTeX will automatically adjust the typeface and font size of the text, headings, chapters, subscripts, footnotes, etc.
We can also use the commands in the following table to set the typeface and relative font size. For example, when the text size of the main body is 10pt, 11pt, and 12pt, the font size of tiny is 5pt, 6pt, and 6pt respectively.
LaTeX has a special font emphasis command: \emph, which has different effects under different fonts and decorations.
For example, if the surrounding text is regular, it is italic; otherwise, it is regular.
