Pinboard header issue (yes, another one)

Like many others, I’m having issues with my margins around my header using the Pinboard theme. I’ve tried everything that’s been offered to others with the similar issue, but it’s not working for me.

Here is the code I have in my CSS:

#site-title {
margin: 0;
line-height: 0;
float: left;
}

#social-media-icons {
display: none;
float: none;
margin-top: 0;
}

#header #s {
display: none;
}

#header #searchform {
float: none;
}

#site-title,
#site-description {
margin: 0;
font-weight: 300;
float: left;
line-height: 0;
}

#site-title img {
margin: 0;
}

**Note that, although it was code used by others, the #site-title img line doesn’t seem right, as img is highlighted in red text. If that’s the issue, I don’t know how to fix it.

Also note that I don’t have a margin on top of my header image, just on the bottom. See my site at https://www.workitoutcoaching.com

Help greatly appreciated!!
