HTML tag rule error

The requirement to use your services as a free member is I have to post a hyperlink back to your website. That is what I did in my footer section by copying and pasting the Href tag supplied.

I am getting an error from Visual Code and Visual Studio 2022 Community Edition. The href tag does not follow HTML 5 best standards. To follow the standards this needs to be in the href

rel=“noopener”

Here is the href tag Rule

Thanks for pointing this out! Could you specify where did you get the hyperlink? Is it from this modal window?
