usepackagevarwidth

The varwidth package is a LaTeX package that provides a command to create boxes with variable width. This means the width of the box can be adjusted based on its content, rather than being fixed beforehand. The primary command provided by the package is \verb|\varwidth|.

The \verb|\varwidth| command takes two arguments. The first argument is the content that will be placed inside the box, and the second argument is an optional length that specifies the maximum width the box can occupy. If the content is narrower than the maximum width, the box will shrink to fit the content. If the content is wider, the box will expand up to the specified maximum width, and the content will be broken or wrapped within that width.

This command is particularly useful for situations where you need to enclose text or other material within a box, but you want the box to adapt dynamically to the amount of content it holds. For example, it can be used to create captions, side notes, or other elements where precise width control is difficult or undesirable. The varwidth package simplifies the process of creating such flexible boxes, making it easier to achieve aesthetically pleasing and well-formatted documents.
