The hyperref.sty package in LaTeX is used to add hyperlinks to a document. This allows readers to click on links within the document and be directed to another page or external website. It also enables the creation of clickable references, citations, and table of contents.
To add hyperlinks, you first need to include the hyperref package in your document's preamble. Then, use the \href{URL}{text} command to create a hyperlink. The URL is the web address or file path that you want to link to, and the text is the text that will be displayed as the clickable link.
Yes, you can customize the appearance of hyperlinks by using the \hypersetup command in your document's preamble. This allows you to change the color, style, and other properties of hyperlinks. You can also use the \url{URL} command to create a hyperlink that displays the full URL instead of just the linked text.
To create a table of contents with clickable links, you need to add the hyperref package and use the \tableofcontents command in your document. This will automatically create clickable links for each section or chapter in your table of contents. You can also customize the appearance of these links using the \hypersetup command.
One common issue is that hyperref.sty may conflict with other packages that also modify the table of contents or references. If this happens, you can try loading hyperref.sty last in your document's preamble or use the \usepackage[hidelinks]{hyperref} command to prevent the package from altering the appearance of links in your document.
