How can I show 4 latest articles in ascending order? Lets say I have 10 articles, tenth being the last one created.
I want my view block to show 4 latest articles, but in ASCENDING order.

7,8,9,10 - something like this.

Can I somehow filter out the exact number of latest articles?
Just output the rows you need and reverse them with CSS.

.view-content {
  display: flex;
  flex-direction: column-reverse;
}
