removing shadow in header

Assuming you are using a child theme the solution would be to create a new CSS file inside your child theme’s root (custom.css) and add this snippet:

text-shadow: unset !important; – this will remove all text-shadow-s through out the site.

However, if you want just to remove shadow from your site name, you have to do this in your custom.css:

.close, h1, h2, h3, h4, h5, h6 {
    text-shadow: none !important;
}

And to remove shadows for menu items (About Us, Wines, etc.) add the following snippet in your custom.css file:

.navbar .brand, .navbar .nav>li>a {
    text-shadow: none !important;
    color: #777;
}

Make sure you have enqueue-d custom.css in in your child theme’s functions.php

Hope this helps!
