Blaze-from-html is an extremely useful, though not a perfect, solution. It can be used with an advantage for capturing the skeleton of a page. For example, it can be used to capture the designs from the skeleton or bootstrap (http://getbootstrap.com) examples.
Once reverse engineered, it is easier to hook user data types into it to render the page the way we want it. Other tools which are useful in this context are pandoc (https://pandoc.org - a generic document converter for many document types) and hakyll (https://jaspervdj.be/hakyll/ - static website generator).
