How to change footer background color on one page

Site URL: http://liaheinze.com

Hello! 
I'm trying to change the background color of the footer on only one page – or better yet, I want to make it transparent so it adopts whatever background color the rest of the page is. Any insight? Thanks!

Add to Page Settings > Advanced > Header (If you use Personal Plan > Edit Page > Add Code Block)

<style>
  footer#footer-sections .content-wrapper {
    background: green !important;
}
</style>

Ah, thank you! There's still some white space that's not being affected around the footer.. would you mind taking one more look at it? Thanks! @tuanphan

new code

<style>
footer#footer-sections .content-wrapper, footer#footer-sections .section-background {
    background: green;
}
</style>

Much closer! But there's still a white space when the widow is resized, between the footer and the rest above...
Thanks again for your assistance.

Can you take a screenshot?

and you want to change footer color or???

@tuanphan

I want the footer color to stay as it is.. the same as the background color above it. When I resize the window in certain ways though, there is a white gap that appears between the footer and the rest above. Don't know why. 

Can you share link to page in screenshot?

@tuanphanThank you very much, this helped me massively although it also caused another issue with my text colour being unreadable so I added another line for that however it does not change any heading text, only paragraph. Is there a way to also change any heading text colour in the footer for this page only?

<style>
 footer#footer-sections .content-wrapper {
    background: black !important;
    color: white !important;
}
</style>

EDIT:
Resolved this by adding another stanza for the h3 specifically, see below.

<style>
 footer#footer-sections .content-wrapper {
	background: black !important;
	color: white !important;
 }
  footer#footer-sections .content-wrapper h3 {
	color: white !important;
 }
</style>

Thanks again to tuanphan for the original post response.
