I would suggest that, in general, people intending to write code-generators and the like should first learn how to structure an html page correctly before building their systems. From a cursory glance at the example code given on the home page I note:
Redundant code - An <h4> tag being the sole contends of a <div>. (The div is redundant).
An <h4> tag under an <h2> tag, with no <h3> tag.
An <h1> tag which appears to have closed divs above it, i.e. it is not at the start of the HTML page (as it would be read by a page-to-speech utility, or a search engine bot). This suggests possible accessibility and SEO issues.
