Envoking Testing Module in Code Pen Editor

I am done with my code for Tribute Page but have no idea on how to envoke the testing module to verify that my code is bug free???

first you can use the Analyze HTML and Analyze CSS tools in codepen

second, you need the test suite, if you have forked the provided pen, you should have it included already, or you will need to add it

Actually I only have Analyze JS in my dropdown but played around a bit and realized that all I had to do was insert this command above Main in my HTML and looks like the Analyzer is now working! Thanks!

Sorry forgot to add the command:

there is the dropdown for each box, look at the arrow in the css and html box to see the “Analyze HTML” and “Analyze CSS” tools
