Do you want to inspect the raw html output of your Gravity PDF? With this simple url argument you can do that.
Add ?html=1 to the PDF url
It’s quite easy. First open a PDF inside your browser. It will have an url like this:
https://gravitywp.com/pdf/5e3ebbb1cb8e3/18823/
Now add behind this url the arguments: ?html=1. This should look like this:
https://gravitywp.com/pdf/5e3ebbb1cb8e3/18823/?html=1
The PDF opens now without processing it to the PDF itself. This makes it way easier to inspect the HTML and styles used inside the PDF. You can only do this when you have edit rights (as an administrator you usually do) in Gravity PDF.
