The document discusses the CSS position property, which specifies the type of positioning for an element. There are four position values - static, relative, fixed, and absolute. Elements are then positioned using top, bottom, left, and right properties. These positioning properties work differently depending on the position value. The document provides examples and explanations of each position value.

- 3. The position Property • Elements are then positioned using the top, bottom, left, and right properties. However, these properties will not work unless the position property is set first.

- 4. position: static; • HTML elements are positioned static by default. • Static positioned elements are not affected by the top, bottom, left, and right properties. • An element with position: static; is not positioned in any special way; it is always positioned according to the normal flow of the page: Call US: +91-9915337448 Email Us: info@webtechlearning.com
- 5. position: relative; • An element with position: relative; is positioned relative to its normal position. • Setting the top, right, bottom, and left properties of a relatively-positioned element will cause it to be adjusted away from its normal position. Other content will not be adjusted to fit into any gap left by the element. Call US: +91-9915337448 Email Us: info@webtechlearning.com
- 6. position: fixed; • An element with position: fixed; is positioned relative to the viewport, which means it always stays in the same place even if the page is scrolled. The top, right, bottom, and left properties are used to position the element. • A fixed element does not leave a gap in the page where it would normally have been located.

- 7. position: absolute; • An element with position: absolute; is positioned relative to the nearest positioned ancestor (instead of positioned relative to the viewport, like fixed). • However; if an absolute positioned element has no positioned ancestors, it uses the document body, and moves along with page scrolling. • A "positioned" element is one whose position is anything except static.

- 9. Overlapping Elements • When elements are positioned, they can overlap other elements. • The z-index property specifies the stack order of an element (which element should be placed in front of, or behind, the others). • An element can have a positive or negative stack order: Call US: +91-9915337448 Email Us: info@webtechlearning.com
