After you choose a theme that defines the basic look and feel of your online store, you can customize the theme to suit your needs. You can access your theme settings from your PrintNow admin by using the Site Themes Editor, or you can create an FTP account in Domain Tools and post changes from your desktop with a FTP client like FileZilla that supports explicit FTP over TLS Encryption . The Site Themes Editor includes tools that you can use to add, remove, and edit files and folders.
Print Store themes are compatible with Bootstrap 4. Bootstrap is an open source toolkit for developing with HTML, CSS, and JS. Print Store code theme structure is easy to follow and integrating HTML themes you purchase on the internet can be done very quickly if you are comfortable with some basic coding. PrintNow has development services if you need some assistance in getting started.
Before getting started modifying Site Themes, it's essential to back-up your theme. You can easily duplicate themes using Site Themes and publish themes along the way. As the sites look and feel is coming together, you can also configure your pages and products.
