Learn how to use the position property in CSS effectively.
Positioning is an important aspect of web development as it determines the layout and appearance of elements on a webpage. By using the position property, you have the ability to precisely control the placement of elements.
There are five possible values for the position property: static, relative, absolute, fixed, and sticky.
Static positioning
The static value is the default positioning for elements. Elements with static positioning are displayed in the normal page flow, without any specific placement adjustments.
Relative positioning
When an element has position: relative, you can use the offset properties (top, right, bottom, left) to position it with an offset from its original position. These offset properties accept length values or percentages to control the positioning.
For example, let’s say we have a parent container, a child container, and an inner box with some text. By setting position: relative on the inner box, we can now use the offset properties to adjust its position relative to its containing elements.
Absolute positioning
With position: absolute, an element is removed from the document’s flow and it no longer follows the original page positioning. The element is positioned based on its closest non-static ancestor, which means you can use the offset properties to precisely position it.
Using position: absolute, you have the ability to move the element around using the offset properties (top, right, bottom, left). The coordinates for positioning are relative to the closest non-static ancestor, giving you more control over the element’s placement.
Fixed positioning
Elements with position: fixed are also removed from the document’s flow, similar to position: absolute. However, with position: fixed, elements are always positioned relative to the window, regardless of the scrolling of the page.
By using position: fixed, you can create elements that stick to a specific position on the screen, even when the user scrolls. This is useful for creating navigation bars or other elements that should remain visible at all times.
Sticky positioning
position: sticky is a relatively new addition to CSS and is still not widely supported in all browsers. This value is useful for creating elements that “stick” to the screen as the user scrolls, much like the first letter in a contacts list. Currently, position: sticky requires JavaScript to achieve the same effect in older browsers.
By understanding and utilizing the different values of the position property, you can have better control over the layout and positioning of elements on your webpages.
