The above id will not work on anyones site but mine, the one I used to test this on.
The upside is that you get all the regular styling of the other text blocks of your site/page.
If you need help discovering the id of the text block let us know. Please do set up the text block exactly as you want it to appear without the border before asking. We will need a detailed description of where the text block is on the page. Then once we get the id we can give you specific CSS.
Thank you for the reply. Please can you assist with this.
