Short background about HTML5 and EPUB3 

eBook publishing is not in its baby steps anymore, indicating that the publishers’ goal is not just to digitize books and sell it online. Now, interactivity, creativity, multimedia, and hyperlinking are significantly enhancing the publishing domain.

No one knows what the future standard for digital publishing will be, but HTML5 and ePub3 remain as the major players in eBook format.

Many people also feel that since we have HTML5, there is no need for ePub3 as it is just yet another standard. But both are important to complete your book to make it more accessible to the readers. It is usually done with epub3 conversion and formatting services from reputed vendors.

Short Background

HTML5 is developed by WHATWG (Web Hypertext Application Technology Working Group), which is now a part of W3C (World Wide Web Consortium). It is the fifth revision of HTML and is considered as one of the most widely used standards on the web. This revision is a massive step forward where it introduced many specifications such as video, audio, drawing 2D objects, tags for articles etc.

Due to these additions, HTML5 gained popularity among leading websites and applications. On the other hand, ePub3 is a specification for digital publications developed by the International Digital Publishing Forum (IDPF) as a successor to earlier versions.

ePub3 is a standard that is nothing but HTML documents packed together in a file. The actual files are defined by documents that can be read like chapters of a book.

It also adds a table of contents so that users can easily navigate between different sections. Therefore, ePub3 is not competing with HTML5; rather it is complementing the existing standard.

Why Should Corporations Adopt ePub3 Format? Advantages of Publishing ePub with HTML5 

ePub and HTML5 have become an incredible standard in the publishing industry. The relationship between both ePub3 and HTML5 is so strong that the former relies heavily on the latter.

The development of the ePub has created a new content interchange format for digital publications based on XML and web standards. The HTML5 encompasses all previous HTML versions and provides a standardized approach to incorporating multimedia and graphical content in publications.

The ePub3, on the other hand, utilizes HTML5 and CSS3 to offer media-rich interactive eBooks to publishers. This is why both standards are tied to each other to meet the needs of the eBook publishing platforms. Now, let’s discuss some of the advantages of using HTML5 and ePub3 for publishing:

  1. Styling and Layout
