Summary  
This chapter explains how the CSS position property (static, relative, absolute, fixed, sticky) and offset properties (top, right, bottom, left) control element placement both inside and outside the normal document flow.

General domain of usage  
Web page UI layout (e.g., pop-ups, modals, mobile menus)

In modern web development, we often need to place elements outside the normal flow, for example, showing text over a product card, opening a pop-up or modal, or displaying a mobile menu. All of this is handled using the `position` property.
```css
position: static | relative | absolute | fixed | sticky
```

The `position` property changes how an element is placed on the page. By default, every element is `position: static`. Once you switch to another value, you can also use `top`, `left`, `right`, and `bottom` to control its exact location.
## Default Document Flow
By default, elements appear on the page in the same order as in the HTML. This natural flow should be kept unless positioning is required for specific UI behaviors like popups, modals, dropdowns, or mobile menus.
