A couple of questions about this cookbook recipe:
1- The flow does not match the picture. As a matter of fact, the flow has a bad CSS selector. As far as I can remember this was corrected at some point. I am not sure how come it is wrong now. The text in the recipe explains to select the correct CSS for the purpose
node-red-latest-version and the flow does not reflect this.
2- Now a question related to the html node that is puzzling me What is the purpose of the first field with the label
Property ? If it is left empty the node works fine. In which cases one would enter a value in this field ?
