x
The x
CSS property defines the x-axis coordinate of the top left corner of the SVG <rect>
shape, <image>
image, <foreignObject>
viewport or nested <svg>
viewport relative to the nearest <svg>
ancestor's user coordinate system. If present, it overrides the element's x
attribute.
Note:
The x
property only applies to <rect>
, <image>
, <foreignObject>
, and <svg>
elements nested in an <svg>
. It has no effect on the outermost <svg>
elements itself, and does not apply to other SVG elements nor to HTML elements or pseudo-elements.
Syntax
/* length and percentage values */
x: 40px;
x: 40%;
/* Global values */
x: inherit;
x: initial;
x: revert;
x: revert-layer;
x: unset;
Values
The <length>
and <percentage>
values denote the x-axis coordinate position of the top left corner of the SVG element container.
<length>
-
As an absolute or relative length, it can be expressed in any unit allowed by the CSS
<length>
data type. <percentage>
-
Percentages refer to the width of the SVG
viewBox
, if declared, otherwise, the percentage refers to the width of the current SVG viewport.
Formal definition
Initial value | 0 |
---|---|
Applies to | <svg> , <rect> , <image> , and <foreignObject> elements in an svg |
Inherited | no |
Percentages | refer to the width of the current SVG viewport |
Computed value | the percentage as specified or the absolute length |
Animation type | by computed value type |
Formal syntax
x =
<length-percentage>
<length-percentage> =
<length> |
<percentage>
Examples
Defining the x-axis coordinates of SVG shapes
This example demonstrates the basic use case of x
, and how the CSS x
property takes precedence over the x
attribute.
HTML
We include four identical SVG <rect>
elements; their x
and y
attributes values are all 10
, meaning the four rectangles are all in the same location, 10px
from the top and left corner of the SVG viewport.
<svg xmlns="http://www.w3.org/2000/svg">
<rect width="100" height="100" x="10" y="10" />
<rect width="100" height="100" x="10" y="10" />
<rect width="100" height="100" x="10" y="10" />
<rect width="100" height="100" x="10" y="10" />
</svg>
CSS
We style all the rectangles to have a black border and be slightly transparent, so overlapping rectangles are visible. We provide each rectangle with different fill and x
values.
svg {
border: 1px solid;
width: 300px;
}
rect {
fill: none;
stroke: black;
opacity: 0.8;
}
rect:nth-of-type(2) {
x: 3em;
fill: red;
}
rect:nth-of-type(3) {
x: 180px;
fill: yellow;
}
rect:nth-of-type(4) {
x: 50%;
fill: orange;
}
Results
The left edges of the rectangles are at 10
(from the attribute), 3em
, 180px
, and 50%
, respectively. The SVG is 300px
wide, so the last rectangle's left side is at the 150px
mark.
