How do I create a card layout without the use of repeaters?

[x321]

I have about 16 or 17 cards that I want to layout on the home page in a grid format. This can be done easily using a repeater by setting the layout as card format. But without using a repeater or dynamic data how do I achieve the same card layout where a card will move from one row to the next when you resize the browser window. I do not want each card to change its original size or the distances between cards.
