If you use Bootstrap and are more towards "static" websites, I recommend Bootstrap Studio (https://bootstrapstudio.io/). I used it on and off. Last time, I used it to make one-off HTML, then edit the rest by hand (meaning, I can't return to the app again to make changes).

But recently, I used it to develop https://momenial.com/ with 100% editing in the app. Meaning I can use the app to make changes. I _do_ still need to make minor edits (that I think I can automate using a script).

It's not perfect (e.g. it can't import existing design, gosh I wish!), but it gets the job done for design-illiterate people like me.
