Hi Tylerr,
What’s the final result you’d like to achieve? The problem with the header height is that the header element contains the navigation as well. Therefore, as long as it’s so, the height stretches to include the navigation. However, if you like to eliminate that space on top of the header image, so that the image’s height, which is 140px, fits inside its container without any extra space, here’s the CSS:
.hgroup-wrap {
display: none;
}
Make sure you put this at the bottom of your child theme’s stylesheet or custom CSS editor so that it takes precedence over the previous rule.
I hope this helps, but if I didn’t understand your request correctly, feel free to post again.
