Positioning
This lesson discusses the positioning properties in CSS and how they affect the positioning and arrangement of elements on a web page.
Positioning
Static
The position
property is used to set the positioning behavior of an
element. The position property can be set to static
, relative
,
absolute
, fixed
, or sticky
. The static
value is the default
value and does not affect the position of the element.
<div class="container">
<div class="item">Item 1</div>
<div class="item">Item 2</div>
<div class="item">Item 3</div>
</div>
The code above shows an example of the position
property. In this
example, the position property of the <div>
element is set to static
,
which is the default value.
Relative
A relative
position is used to set the position of an element relative
to its normal position. The element is positioned based on its normal
position in the document flow, and then offset by the specified values.
<div class="container">
<div class="item">Item 1</div>
<div class="item">Item 2</div>
<div class="item">Item 3</div>
</div>
The code above shows an example of the position
property with a
value of relative. In this example, the position of the <div>
element is set to relative
, and the top
and left
properties are used
to offset the element by 10 pixels.
Absolute
An absolute
position is used to set the position of an element
relative to its nearest positioned ancestor. If no ancestor is
positioned, the element is positioned relative to the document body.
<div class="container">
<div class="item item1">Item 1</div>
<div class="item item2">Item 2</div>
<div class="item item3">Item 3</div>
</div>
The code above shows an example of the position
property with a
value of absolute
. In this example, the position of the <div>
elements is set to absolute
, and the top
, right
, bottom
, and left
properties are used to position the elements in the container.
Fixed
A fixed
position is used to set the position of an element relative to
the viewport. The element remains fixed in the same position on the screen
even when the page is scrolled.
<div class="container">
<div class="item item1">Item 1</div>
<div class="item item2">Item 2 - Fixed</div>
<div class="item item3">Item 3</div>
</div>
The code above shows an example of the position
property with a
value of fixed
. In this example, the position of the <div>
element is
set to fixed
, and the top
and right
properties are used to position
the element on the screen.
Sticky
A sticky
position is used to set the position of an element relative to
its containing block. The element remains in the normal flow until it
reaches a specified scroll position, at which point it becomes fixed
.
<div class="container">
<div class="item item1">Item 1</div>
<div class="item item2">Item 2 - Sticky</div>
<div class="item item3">Item 3</div>
</div>
The code above shows an example of the position
property with a
value of sticky
. In this example, the position of the <div>
element is
set to sticky
, and the top
property is used to position the element on
the screen.
