This page used to test insertion of an iFrame definition into a “basic” (not “advanced”) code block while the website is hosted under a SquareSpace “basic” plan.
SquareSpace documentation indicates that iFrame definition should not be allowed in a “basic” code block.
The iFrame definition attempted would insert an embedded Google calendar display in the page if successful.
The attempt looked successful, but SquareSpace indicated an upgrade would be needed.
