Reply To: Can't create white space between posts on responsive theme

[Senff]

First of all, I noticed that the titles are yay off on some screen sizes. I doubt you really wanted to give them a left/right padding of 90%???

.entry-header {
    padding: 0 90.0909%;
}

As for the space between articles: there IS space for screens larger than 38.75em because of this:

.hentry + .hentry, .page-header + .hentry, .page-header + .page-content {
    margin-top: 7.6923%;
}

But below that, the articles don’t have a top margin, which is why there’s no space in between.
