Vertical line next to site title

Hi, I am looking for a code that vertically separates the site title and the navigation by placing a 1px vertical line (|) next to the site logo (similar to the screenshot). Can anyone help with this? It should be responsive across different browser sizes, spanning the whole height of the header, so unfortunatly it's not enough to put a 

.header-title-text::after { content: " | ";  } 

in. 

My site is https://tetra-accordion-k45t.squarespace.com/, password is squarespace.

This Custom CSS would add a vertical line:

.header-title {
    border-right: 1px solid white;
}

But to get the line to span the entire height, you'll also want to add this:

.header .header-announcement-bar-wrapper {
  padding-top: 0vw;
  padding-bottom: 0vw;
}
.header-title {
  padding-top: 1vw;
  padding-bottom: 1vw;
  padding-right:2vw;
}
.tweak-fixed-header:not(.sqs-edit-mode-active):not(.sqs-site-styles-active) .header.shrink .header-announcement-bar-wrapper {
    padding-top: 0vw;
    padding-bottom: 0vw;
}

Let me know if that works.

Thanks so much, Ziggy!
