Probably a very stupid question but I've been out of the game a long time now! For years I have been developing websites using HTML and CSS and making very responsive and modern websites that also work very well with mobile and then uploading them to a webserver. I have recently been using Netlify as my server of choice.
The catch is that Netlify is a static webserver and I am trying to have some sort of CMS for my clients to edit their websites without looking at code. The problem is that I want to use the same CSS and HTML code for my client's existing websites without having to completely rebuild them in JS/React.
I tried using Netlify CMS + Gatsby template with the hope that I could just paste my HTML and CSS code into it but I was mistaken!
Is there any method for me to use my existing HTML and CSS static websites on an end-user CMS?
