Designing a website - transfer to Wix

Wix uses its own templates and design system, I'm not sure there is an easy way to design it and transfer that design to them.

This is not an easy a project as you may think it is. Maybe 10+ years ago you could get away with slicing up a website image in Photoshop, export it for web and work on it. In today's environment of mobile friendly designs and dynamic engagement it is not that simple. While you can make much of your imagery for your site in Photoshop, you will need to slice up your images and then place that within the HTML/CSS of your site. While you may not be working 100% in the code in a solution like Wix, you will need to understand how to slice your images for each break point in your display (desktop, tablet, mobile) and then you will likely still need CSS to mimic what you want the fonts/styles/etc to look like for other elements of your site.

Personally if you are not comfortable with code, I would start with a Wix template and edit your images in Photoshop and then swap out the images on the Wix site with your Photoshop images.
