Body Tag All Pages Unresponsive To Changing Font Size

So I have been using the Wizardy technique on sites I have been building. https://wizardry-technique.webflow.io/

It requires a person to adjust the Body All Pages tag so that inherited items via font size are inheriting 1vw.

All well and good, enjoying the use of the technique. But ever since I created a read-only link for a separate issue the Body tag is completely unresponsive to any changes in font-size. Which has ruined my layout and thrown a spanner in the works.

Has anybody else experienced this? Any ideas on what has gone wrong for me?

Cheers
