How do I ensure that items in a container are centered regardless of screen size?
I am trying to create a responsive/dynamic layout on a web-page that has a container div and some results/items (divs) inside. I would like them to flow within the available width but have uniform margin/alignment within the centered div which I am struggling to achieve. Here are three images of what I want to achieve. This could be a desktop, a tablet and a phone:
So far I've had to go with a cut-off width of e.g. 800px and two different layouts, but that's not optimal. The container should be dynamic, for example 90% width but the items inside fixed width of 200px. I can use flow:left; or display:inline-block; to flow the items inside, but they will always be left aligned, so that when one "slides" down to the next line, the remaining are sitting to the left with a gap to the right.
This is probably a common use case, and I'm happy to be referred to other answers, but I haven't been able to search correctly in order to find the answer.
EDIT: I know that I can do this with JavaScript. I could probably use getBoundingClientRect on the container and with code adjust the margin of the items, but there must be a CSS solution :)
