At itselftools.com, we’ve amassed a wealth of knowledge from developing over 30 projects combining the robust capabilities of Next.js and Firebase. In this article, we’ll demonstrate how to effectively integrate custom fonts into your Next.js applications using CSS Modules, enhancing the visual richness and user experience of your sites.

What are CSS Modules?

Before we dive into the nuts and bolts, let's briefly touch on CSS Modules. CSS Modules are a popular approach in the web development community used for styling components.
