XF 2.0 Make header narrower from top to bottom?

[Steel Hyaena]

I'm looking around and not finding how to do that. I don't want much above and below the logo/banner thing I am using.

Not to nag, but this has my work on my site ground to a halt. All I have gotten so far was contact from someone who wanted money to do it and that's not what I want. A link to where I can find the selector(s) I need would be wonderful. Thank you in advance!

Depending on the size of your logo, you can mess with this.
Max size you could put your logo size.
Then you would go up in number to be narrower from top to bottom.
Meaning -1 would be less narrow, -10 would be narrower.
add to extra.less template.

.p-header-logo.p-header-logo--image img {
    max-height: 100px;
    margin-top: -9px;
    margin-bottom: -9px;
}
