Understanding the CSS position Property
The position property is used to determine the positioning method of an element on a web page. It has several values, each with its unique behavior. Let’s explore them one by one.
1. Static Position (Default)
The default value of the position property is static. Elements with position: static; are positioned according to the normal flow of the document. This means they follow the order they appear in the HTML.
.example {
position: static;
}2. Relative Position
When an element is given a position: relative;, it is positioned relative to its normal position in the document flow. You can use the top, right, bottom, and left properties to adjust its position from its default location.
.example {
position: relative;
top: 10px;
left: 20px;
}3. Absolute Position
An element with position: absolute; is positioned relative to its nearest positioned ancestor (an ancestor with a position value other than static). If no positioned ancestor is found, it positions itself relative to the initial containing block (usually the <body> element).
.example {
position: absolute;
top: 50px;
left: 100px;
}4. Fixed Position
Elements with position: fixed; are positioned relative to the viewport, which means they stay in the same place even when you scroll the page. Fixed elements are often used for headers, footers, or sidebars that need to remain visible at all times.
.example {
position: fixed;
top: 0;
left: 0;
}5. Sticky Position
position: sticky; is a unique value that combines aspects of both relative and fixed. An element with sticky positioning is initially in the normal flow, but it becomes fixed once it reaches a specified scroll position.
.example {
position: sticky;
top: 20px;
}Practical Examples
Now, let’s put our knowledge of the position property to use with practical examples.
