How to change background color of an entire section with css?

[subh3]

I'm new to shopify and been trying to change the background of the following section by adding code to the :

#shopify-section-template--14585333410850__d4b22187-d4b2-485b-b8db-684699d2e882{
 background-color: #0000!important;
}

But it didn't worked and showed an error message that "ID sector can't be used". 

Can you help me with a solution please?

Hi @subh3 , 

Maybe its not the right selector, Would you mind to share your URL website and point out the specific section you edit to? Thanks!

#shopify-section-template--14585333410850__d4b22187-d4b2-485b-b8db-684699d2e882{
 background-color: #000!important;
}
