more than 4 columns in blogs page

since the maximum columns for blog page is 4, is there a code for more columns, say perhaps 5?

this is what i tried out, under custom CSS:
 

@media screen and (min-width:600px) {
.blog-basic-grid {
    grid-template-columns: repeat(5,minmax(0,1fr)) !important;
	}
}

but the issue is that it alters the number of posts in each page and also the button (next page) at the bottom right is in the middle now.
