HTML5 Document Outliner

Sunday, October 21st, 2012

Recently, while preparing a training session on HTML5 Semantic and Structural Elements, I was rather intent on conveying the importance of an application’s overall markup and structure, while also expressing the importance of not being overly concerned with the absolute technical “correctness” of each and every element used.

With this in mind, providing a general overview of HTML5 sectioning content, and HTML5 Document Outlines, seemed appropriate points to emphasize.

Before doing so, I was looking to utilize a simple utility to provide a means of visualizing an HTML5 Document Outline, and the very useful Chrome Extension, HTML5 Outliner, proved to be an ideal tool for the task.

In particular, the HTML5 Outliner is quite helpful in validating the overall structure of single page web applications, whereby the constructed page is based on multiple disparate client-side templates being rendered at runtime; in which case it can be rather useful to have a holistic view of an application’s structure.

And so, if you are building modern client-side web applications, and using Chrome, if you haven’t done so already, I certainly recommend installing the HTML5 Document Outline for quickly viewing an application’s overall structure.
