Header Logo Size Increase in Highend Minimal Template

Hello,

While I have found and tried to follow the handful of other posts on the topic of wanting a logo to appear larger in the header of the minimal theme, I’m having no luck adjusting mine. Every time I’ve tried adding and saving a bit of CSS code that I see suggested, like:

#logo img {
max-height: 100%;
}

nothing ever actually changes with my logo size on the live page. I’ve tried about three different solution snippets of code I’ve seen suggested in other topics threads here. Really I’m not even sure where exactly in the 259 lines of code I currently see by default in the Custom CSS field to paste code, and experiments haven’t helped, and make me nervous.

So, I’d like my logo to appear a good deal larger in the header of my site http://webnewpoint0.com. The logo file I created is 72px high as recommended by the template. I’d love for it to fill very close to the entire height of the header.

Thanks very much, in advance, for your help.
