Header unwanted shadow-box

[ArjunPCD]

Hello,
I am trying to figure out how to remove this border at the bottom of the navbar,

I have looked at the css files to find any borders or shadow-boxs that might cause this, i have also inspected the whole header but i am just unable to find what creates this.

I know there is a checkbox "show seperator line" which is currently unchecked.

Thank you,

Share link to store? And what theme?

The current websites design is still in dev, the version is Dawn version 14.0.0

I don't see this shadow in dawn theme examples. Need to look at your store to figure out what's the problem

Share a preview link, so we can see that. It's normally a little CSS-Code.

Hello @ArjunPCD 
Thank you for submitting your query to the Shopify community. I’d be happy to assist you. Could you please provide the store URL and password (if it’s password-protected) so I can review and get back to you with an update?

Sorry, I actually solved, 
I have conditioned a different class for the home page (I have positioned it in absolute) and the other pages since I realized i actuly need a border in the other pages:

  {% if request.page_type == 'index' %} header--home{% endif %}

I am new to shopify and to liquid,  I'll be still glad if you can teach me how to share a preview of a website which is not live yet.
thank you
