How can I use HTML safely?
HTML sanitization is the process of examining an HTML document and producing a new HTML document that preserves only whatever tags are designated “safe” and desired. HTML sanitization can be used to protect against attacks such as cross-site scripting (XSS) by sanitizing any HTML code submitted by a user.
What is sanitization in XSS?
Summary. xss-sanitize allows you to accept html from untrusted sources by first filtering it through a white list. Sanitizing allows a web application to safely use a rich text editor, allow html in comments, or otherwise display untrusted HTML. If you trust the HTML (you wrote it), you do not need to use this.

How can I change the defaults in sanitize HTML?
In order to change the defaults, you create your own object containing the defaults you would like. The main sanitize-html site has some good examples on how to slightly modify the built in defaults. For my testing, I wanted to allow everything the defaults allowed, except for the tag. This is how I did it.
