Need a full-width container in some places, but inside-article forces padding.

I am using the default padding on containers which is fine for the majority of my site. However there are a small number of containers where I would like the container to have no left or right padding. However, I'm finding is that padding is set on .inside-article and all of my containers (divs) on each page are within inside-article. So how would I create containers that have no padding?

PS. I tried adding a full-width-content CSS class to override the padding, but all this ended up doing was overriding padding on text columns and sub-containers

.full-width-content {
padding: 0px !important;
}
