How do I insert a full width line (colour #cccccc) under the navigation menu?

Hi Judith,

Any chance you can link us to the site in question?

You can use the private information field.

Let me know :)

Thank you, Ying. I have replied privately.

Try this CSS:

.main-navigation {
    border-bottom: 1px solid #cccccc;
}

Adding CSS: https://docs.generatepress.com/article/adding-css/

No need to type your reply in the private info field - that field is only use for sharing site URL and credentials if needed :)

Thanks, Leo. It's so simple, clearly. I appreciate your prompt support. Best wishes, Judy.

No problem :)

Leo, actually I think your Youtube videos showing how to set up various elements on the site are terrific. You are a great teacher. I'm impressed. Kind regards, Judy.

Thanks Judith!

I need to get back to making videos again :)
