Uniform Front and inside Page Headers

First I adjusted the height of my front and inside pages to be uniform with a variation of the code found in this forum:

.custom-header-media img {
    height: 75vh !important;
    position: relative !important;
}
.custom-header {
    height: 75vh !important;
}

That worked fine. I have viewed it on chrome and safari on a Mac.

Next I want to move the site-branding down to the bottom of the header area, like it is on the front page. When I change the padding in my browser tools I get the result I want on screen. But when I upload the code into my child theme there is no result. the logo, site title, and tagline just stay at the top. I must be missing something. Here is the code I am using:

/*Move site branding to bottom of header on interior pages*/
	.site-branding?{
	 padding:?40em 0 !important;
	}	

Help would be much appreciated.
