There a few things you have to consider.
First of all; with justify-content
you define how remaining space is handled. By using space-between
your items will be aligned so that the space between them is equal, by setting it to center
the remaining space will be around all items, with all items stuck together.
In your case though, there is no remaining space, because your items actually stretch the div. So that doesn't help you.
Next; you've set the width of an item to 50%
. Which is fine, your item
's will be 50% of the viewport. That's because your grid will implicitly be 100% of the viewport. But because your image overflows the box, you can set margins if you want, and they will put the items further apart, but you need big-ass margins to actually see them. Bigger then the overflowing of your image.
So, to fix this, you make the images responsive by making them as width as the item;
.item img { display: block; height: auto; width: 100%; }
But that poses another problem; flexbox tries to size it's flex items to fit it all into the flex container. So you'll see that it automatically resizes your items so they will all fit in. To fix this, you have to explicitly force the width of your items;
.item { flex: 0 0 50%; }
Which is a shorthand for;
.item { flex-grow: 0; flex-shrink: 0; flex-basis: 50%; }
So basically you say; make my item 50% of it's container, and don't use your awesome algorithm to try to make it bigger or smaller.
Now you've got what you want, and you can use margin-right: 20px
for example to create a 20px space between your items.
Full snippet;
.grid { display: flex; width: 100%; }
.item { flex: 0 0 50%; margin-right: 20px; }
.item img { display: block; height: auto; width: 100%; }
.article-scroll-mobile {
box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2);
flex-wrap: nowrap;
text-align: center;
overflow-x: auto;
-webkit-overflow-scrolling: touch;
/*For iOS smooth scroll effect*/
}

Alternatively, you should now use flexbox to achieve many of the layouts that you may previously have used inline-block for: https://css-tricks.com/snippets/css/a-guide-to-flexbox/
Since this answer has become rather popular, I'm rewriting it significantly.
Let's not forget the actual question that was asked:
It is possible to solve this problem with CSS alone, but there are no completely robust CSS fixes.
The solution I had in my initial answer was to add
font-size: 0
to the parent element, and then declare a sensiblefont-size
on the children.http://jsfiddle.net/thirtydot/dGHFV/1361/
This works in recent versions of all modern browsers. It works in IE8. It does not work in Safari 5, but it does work in Safari 6. Safari 5 is nearly a dead browser (0.33%, August 2015).
Most of the possible issues with relative font sizes are not complicated to fix.
However, while this is a reasonable solution if you specifically need a CSS only fix, it's not what I recommend if you're free to change your HTML (as most of us are).
This is what I, as a reasonably experienced web developer, actually do to solve this problem:
Yes, that's right. I remove the whitespace in the HTML between the inline-block elements.
It's easy. It's simple. It works everywhere. It's the pragmatic solution.
You do sometimes have to carefully consider where whitespace will come from. Will appending another element with JavaScript add whitespace? No, not if you do it properly.
Let's go on a magical journey of different ways to remove the whitespace, with some new HTML:
You can do this, as I usually do:
http://jsfiddle.net/thirtydot/dGHFV/1362/
Or, this:
Or, use comments:
Or, if you are using using PHP or similar:
Or, you can even skip certain closing tags entirely (all browsers are fine with this):
Now that I've gone and bored you to death with "one thousand different ways to remove whitespace, by thirtydot", hopefully you've forgotten all about
font-size: 0
.
