Cross-Referencing in LaTeX
Cross-referencing is one of LaTeXs strongest features. It lets you link sections, equations, tables, and figures consistently. When the numbering changes, references update automatically. With the hyperref package, you can even create clickable links in PDFs.
Labels and References
The \label command assigns a unique identifier to sections, figures, tables, or equations. You can then use \ref to reference the number and \pageref to reference the page number where it appears.
Hyperlinks with hyperref
The hyperref package turns references and citations into clickable links in the PDF. It also adds support for external URLs and email links.
Customizing Links
You can customize link colors and set PDF metadata using hyperref options. This makes your document more professional and reader-friendly.
