Remove line after header

Can you post a link to your site?

I’m sorry it’s still under development, but it should be similar to https://demo.kairaweb.com/satori/
The line I referred to is located below “JUST ANOTHER WORDPRESS SITE” word.
Would you be able to tell me based on that demo? I just would not want to open my site publicly at the moment. Thanks

Try this custom CSS:

.site-header {
	box-shadow: none;
}

An easy way to add custom CSS is to install the Jetpack plugin and activate the Custom CSS module. You’ll then add your custom CSS in the new stylesheet editor that’ll appear in your dashboard, under Appearance > Edit CSS.

As alternatives, you could either install a standalone custom CSS plugin, or create a child theme.

Thank you so much. That did the trick.
