Introduction

In my quest to reform the web, I needed to make an HTML Authoring Tool. I, an author cum maker, need to think like a creator.

Both creators and authors think in contents. Our thought decides to create – for example – a heading, a subheading, and some plain paragraphs.

Authors, however, need to rethink in HTML. To create a subheading, authors need a p element that must follow one of h1, h2, h3, h4, h5, or h6 element in a hgroup element.

Yet, learning resources explain HTML by elements-to-use before content-they-creates; whereas, Authors think by contents-to-create before elements-to-use ... a conflict of expectations.

Moreso, by HTML design, one element may be multi-purpose and still insufficient to markup one content.

Both challenges would make a learner struggle to find information and understand relationships of elements that markup a content. This could result to incorrect use of elements, loss in semantics, incompatibility with user agents, and, finally, bad experience for users at unexpected times.

HTML by Contents pioneers a total content-first HTML learning resource. It explains HTML by contents-to-create to align with an author's mind.

It introduces 10 Content Models to improve the partial hierarchy of the 7 Content Models recorded in the HTML Living Standard. Partial hierarchy because div and p belong to the Flow Content Model but pallows phrasing contents while divallows flow contents.

The cover page provides you with a practical approach and a conceptual approach to using this resource.
