Change post background color


I’m using sidney as wordpress theme for my athlete’s site. I want my site to have a black background. However I cannot manage to make the background of the post page black. Any help?


Your site already has a background image. did you mean that you want the background color of the post have transparent color?if so, you can add css code below using custom css plugin:

.container.content-wrapper {
    background-color: transparent;
