Sidebar Color

Hi jklarich.

I saw a post that I used

What post was that? What was the code you used? Can you post a link to your site? Thanks.

Here is my site: https://grangerwashington.org/

I used this code:

/* sidebar backgrounds to green */
.s1, .s2 {
background: #f3fbc4;
}

but it only changed the primary sidebar and not the secondary one. What should I try?

This is probably related to your other post regarding the display of the sidebars:
