BibTeX, biblatex and biber ⇒ Why do I have highlight on reference's number on Overleaf?

[Sam_Land]

I'm using Overleaf.com to prepare my thesis.

But I notice that my reference citation number are surrounded by colored, rectangular highlight.

I had used overleaf before but I didn't have such highlights. And I failed to find any difference on latex source code of two documents.

The attachment file is the screenshot of such "colored, rectangular highlight".

Any help is appreciated.

Package hyperref is making those boxes for your readers. They indicate a hyperlink to directly jump to the bibliography. They won't be printed.

You can toggle that off by using \hypersetup{colorlinks=false}

Hi Sam,

welcome to the forum!

Or

\hypersetup{hidelinks}

or when loading:

\usepackage[hidelinks]{hyperref}

is your thesis is printed anyway - no visible links needed - no bold, no color, no border, no highlighting.

Or

\hypersetup{
colorlinks=false,
pdfborder={0 0 0},
}

in case Overleaf might use an older version of hyperref.
