Site Description Won't Indent.

https://www.changeincorporated.org

Elegant Theme Chameleon lacked h1 tags in header. They did have in top_info.php. But anyhow.

Recently added seo-friendly-izing stuff to header.php as follows:

[Code moderated as per the Forum Rules. The maximum number of lines of code that you can post in these forums is ten lines. Please use the pastebin]

Now, though the site title indents fine, I can’t get the site description to hide itself off left (don’t want it gone altogether, obv), even with the following additions to style.css:

#site-title {
text-indent: -999em !important;
}

#site-description {
text-indent: -999em !important;
}

Couple questions:
1. Since the h1 tags were in top_info.php, did I not need to do any of this anyhow? My understanding after reading https://www.wpmods.com/make-wordpress-titles-seo-friendly/ was that I should.

2. Any suggestions for making that site description indent appropriately?

Thanks.
