Creating css transitions without using position:absolute

Question

I realize that css animations are a well covered topic, but I'm just wondering about the best way to create simple slide like transitions? Mostly, when you read about slide transitions like that, some kind of position:absolute is assumed. That is not the way content is usually organized in HTML and it shouldn't be. So, if I want to create a transition of one div sliding to the left and one div sliding from the right, what would be a good strategy without assuming that any of those divs has absolute positioning or any other specific transition specific stuff going on to start with? ```

The best way to move elements around when animating is translating using css transforms. For example, to transition when hovering over the container:

```
.this-should-slide-left,
.this-should-from-left {
    transition: transform .25s
}

.container .this-should-from-left {
    transform: translateX(100px);
}

.container:hover  .this-should-from-left {
    transform: translateX(0);
}

.container:hover .this-should-slide-left {
    transform: translateX(-100px);
}
```

Translating makes the transition much smoother as it takes advantage of hardware acceleration plus there is no positioning involved, so you have complete separation between the design of the layout and the design of the animation itself.
