CSSThe position Property
CSS Positioning
CSS positioning is about controlling the placement of elements within a web page.
With CSS positioning, you can override the normal document flow.
The CSS position Property
Theposition property specifies the positioning type for an element.
This property can have one of the following values:
static- This is defaultrelativefixedabsolutesticky
Elements are then positioned to their final location with thetop,bottom,left, andright properties.
CSS position: static
All HTML elements are positioned static by default.
Static positioned elements are not affected by the top, bottom, left, and right properties.
An element withposition: static; is always positioned according to the normal flow of the page:
Here is the CSS that is used:
CSS position: relative
An element withposition: relative; is positioned relative to its normal position in the document flow.
Setting the top, right, bottom, and left properties will causethe element to be adjusted away from its normal position. Other content will not be adjusted to fit into any gap left by the element.
Here is the CSS that is used:
CSS position: fixed
An element withposition: 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 set the final location of the element.
A fixed element does not leave a gap in the page where it would normally have been located.
position: fixed;Notice the fixed element in the lower-right corner of the page. Here is the CSS that is used:
Example
position: fixed;
bottom: 0;
right: 0;
width: 300px;
border: 3px solid #73AD21;
}
CSS position: absolute
An element withposition: absolute; is positioned relative to the nearest positioned ancestor (with position other than static).
However; if an absolute positioned element has no positioned ancestors, it uses the document body, and moves along with page scrolling.
Note: Absolute positioned elements are removed from the normal document flow, and can overlap other elements.
Here is a simple example:
Here is the CSS that is used:
Example
position: relative;
width: 400px;
height: 200px;
border: 3px solid green;
}
div.absolute {
position: absolute;
top: 80px;
right: 0;
width: 200px;
height: 100px;
border: 3px solid red;
}
CSS position: sticky
An element withposition: sticky; toggles between arelative andfixed position, depending on the scroll position.
A sticky element is positioned relative until a certain scroll position is reached - then it "sticks" in that place (like position:fixed).
Note:You must specify at least one of thetop,right,bottom orleft properties, for sticky positioning to work.
In this example, when the sticky element reach the top of the page (top: 0), it sticks to this position:
Example
position: sticky;
top: 0;
background-color: green;
border: 2px solid #4CAF50;
}
