Squarespace's header menu options offer some sleek and user-friendly looks, but it limits us to solid colors and gradient sfor the header background. That's great for clean, minimal designs, but what if you want something with more personality?

That's where a little bit of custom code comes to the rescue! In this tutorial, you’ll learn how to transform your header by using your own custom image for the background. Whether you want a subtle pattern, a brand-specific texture, or a stunning photograph that sets the mood for your entire site, this simple code snippet makes it possible.

Check out the video below to learn how you can use an image for your header background. When you're ready to give it a go, you'll find the codes and steps on my blog at https://insidethesquare.co/squarespac...

Pro Tip: I like to make sure my images are 2500px wide. The height depends on the header design (if the logo and links are big or small) but I always have a minimum of 900px in height for any images I might end up using for the mobile background image code.
