HTML5 APPLICATIONS DEVELOPMENT MANUAL (2016)

8 - Validating HTML5 Code

An important aspect of debugging and testing is to validate code to ensure it is properly interpreted by browsers.

We can use a validator to test code for inaccuracies and syntax errors.

W3C provides a code validation service for all versions of HTML and CSS at https://validator.w3.org/

Validating a Package

Packaging an app is the process of preparing an app for installation on different devices or systems.

Microsoft provides a free tool called the Windows App Certification Kit for testing local apps. The kit is a type of validator that tests your app on your computer before you attempt to package and publish it to the Windows Store.
