I am making a web page and then referencing the third party code, the code needs to do the following:
1: Add XML namespace to HTML tags:
2: Introduce WB.JS in the HEAD header:
3.Paste the WBML code in a location where you need to deploy a key：
These operations I only know that the second step can be edited by the head html, I completed, the first step I can only complete through other tools, the third step, how to complete in hype3?
