how to hide the message "*Accordion Page Settings*/"

Hello! We use accordion functions on the site, but this message "*Accordion Page Settings*/" is always appear on the top left of the first page during loading the site content.
We'd like to know how to hide that message. Any suggestion would help, thank you.

It sounds like you are missing a “/“ just before this text. Look for the line of text wherever you inserted the code. If you need help, please provide a working link to the page.

You have the wrong comment type. It should look like this

@paul2009 Thank you so much for your detail information! Imade it finally.
I understand the difference of comment tag between on HTML and CSS. Once I tried the new script that you recommend, but it did't work properly, and I found another newer script and it's done. Thank you for your help! Your patient and precise support is so special for me like a beginner.
