Vertically and horizontally centers a child element within its parent element using `position: absolute` and `transform: translate()` (as an alternative to `flexbox` or `display: table`). Similar to `flexbox`, this method does not require you to know the height or width of your parent or child so it is ideal for responsive applications.
```html
<div class="parent"><div class="child">Centered content</div></div>
<div class="parent">
<div class="child">Centered content</div>
</div>
```
```css

#### Explanation
1. `position: absolute` on the child element allows it to be positioned based on its containing block.
2. `left: 50%` and `top: 50%` offsets the child 50% from the left and top edge of its containing block.
3. `transform: translate(-50%, -50%)` allows the height and width of the child element to be negated so that it is vertically and horizontally centered.

- Note: that the fixed height and width on parent element is for the demo only.
