Reduce header size?

Site URL: https://thegaragegenius.squarespace.com/

I'm looking to reduce the size of the header with a CSS code (I don't have the upgrade for Code Injection).

This is behind a password wall but happy to share that as well!

Hello @ArtsyQ, When you say "size," do you mean the height of the header? Let me know so I can assist you better. In the meantime, have you tried adjusting its height in the settings? Check out the attached screenshot for reference. If you still need to customize the height further, you can use the following code. (play around with the px values.

1. Navigate to Pages > Website Tools > Custom CSS.
2. Paste the code into the CSS editor.
3. Hit Save and you’re done

/* Styling the Header */
div.header-announcement-bar-wrapper {
    padding-top: 5px !important;   /* Adds 5px padding to the top of the announcement bar */
    padding-bottom: 5px !important;/* Adds 5px padding to the bottom of the announcement bar */
}

add this code into 

.header .header-announcement-bar-wrapper{
   padding: 0px !important; // you can customize the padding as you want
}
