Changing container_24 and grid_24 through style.css

So I am trying to widen the container on my fullwidth template page called team.

In the sytle.css for the theme I created these entries:

.team .container_24{
	width: 1200px;
}

.team .container_24 .grid_24{
	width: 1190px;
}

when I change these on the page through developer tools it works just fine, but for some reason when I updated the style.css it does not work.

Any help would be appreciated. thanks!
