The position
property of an element controls how it is positioned within its
parent element.
Inline Positioning
If the position
property has the value inline
, the element is positioned
according to the layout flow of the parent element (see Controlling the Layout Flow).
Since inline
is the default value, it may be omitted.
Free Positioning
If the position
property has the value free
, the element is freely positioned
inside its parent element with absolute coordinates specified by the x
and
y
properties.
Box {
width: 300
height: 300
Box {
position: "free"
x: 100
y: 100
width: 50
height: 50
color: "red"
}
}
Global Positioning
If the position
property has the value global
, the element is freely positioned
inside the document window with absolute coordinates specified by the x
and
y
properties.
Box {
width: 300
height: 300
Box {
position: "global"
x: 100
y: 100
width: 50
height: 50
color: "red"
}
}
Origin of the Coordinate System
The property origin
specifies the corner where the origin of the coordinate
system lies in the free
and global
positioning modes. By default, origin
has
the value top-left
.
origin
may have one of these values:
top-left
: (0, 0) is in the top-left corner of the parent (free positioning) or the document window (global positioning). X coordinates increase to the right and Y coordinates increase downwards.top-right
: (0, 0) is in the top-right corner of the parent (free positioning) or the document window (global positioning). X coordinates increase to the left and Y coordinates increase downwards.bottom-right
: (0, 0) is in the bottom-right corner of the parent (free positioning) or the document window (global positioning). X coordinates increase to the left and Y coordinates increase upwards.bottom-left
: (0, 0) is in the bottom-left corner of the parent (free positioning) or the document window (global positioning). X coordinates increase to the right and Y coordinates increase upwards.
