<svg>
The svg
element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.
Note: The xmlns
attribute is only required on the outermost svg
element of SVG documents, or inside HTML documents with XML serialization. It is unnecessary for inner svg
elements or inside HTML documents with HTML serialization.
Examples
Nested svg
element
This example shows that nested svg
elements do not need the xmlns
attribute.
<svg
viewBox="0 0 300 100"
xmlns="http://www.w3.org/2000/svg"
stroke="red"
fill="grey">
<circle cx="50" cy="50" r="40" />
<circle cx="150" cy="50" r="4" />
<svg viewBox="0 0 10 10" x="200" width="100">
<circle cx="5" cy="5" r="4" />
</svg>
</svg>
Using dynamic viewport units
In this example, the height
and width
attributes on the svg
element are set using the dynamic viewport value 60vmin
, equivalent to 60% of the viewport's width or height, whichever is smaller.
<svg viewbox='0 0 400 400' xmlns='http://www.w3.org/2000/svg' height='60vmin' width='60vmin'>
<rect x='0' y='0' width='50%' height='50%' fill='tomato' opacity='0.75' />
<rect x='25%' y='25%' width='50%' height='50%' fill='slategrey' opacity='0.75' />
<rect x='50%' y='50%' width='50%' height='50%' fill='olive' opacity='0.75' />
<rect x='0' y='0' width='100%' height='100%' stroke='cadetblue' stroke-width='0.5%' fill='none' />
</svg>
To change the iframe's dimensions try resizing the dotted red border from bottom right corner.
