I figured out why I couldn’t find the code you were referring to. It seems that my website’s code is different from the code generated in the developer tools. My site has its minimum and maximum width values defined by percents, not pixel values like you’re seeing.
I did figure out a fix. For anyone trying to solve a similar problem in the future, I added the following code to my “Additional CSS” section:
.site-header{
border-bottom: solid white 9px;
}
Thanks! I can’t seem to find the code you’re referring to though. I’ve searched through my style.css (and all my theme files, actually) and I can’t seem to find any code matching what you posted. “192” doesn’t appear anywhere in there. Am I missing something?
I’ve already tried looking at it with different browsers; it’s the same for all the ones I’ve tried.
I was logged in as an admin. I just tried logging out–no change.
