creating a custom post layout just like custom page

i used following code to create custom page layout

@media (min-width: 768px) {
.page-template-custom-page-php #main-wrapper {
	width: 100%;
	overflow-x: hidden;
	}
.page-template-custom-page-php #main-wrapper .breadcrumbs {
	margin-left: 10px;
	}
.page-template-custom-page-php .container {
	width: 100%;
	}
.page-template-custom-page-php #content {
	width: 100%;
	margin: 0 auto;
	display: inline-block;
	}
.page-template-custom-page-php .row {
	margin-left: 0;
	margin-right: -30 px;
	}
}

is it possible to do something like this for posts also
