SVG <rect>

SVG Shapes

SVG has some predefined shape elements that can be used by developers:

  • Rectangle <rect>
  • Circle <circle>
  • Ellipse <ellipse>
  • Line <line>
  • Polyline <polyline>
  • Polygon <polygon>
  • Path <path>

The following chapters will explain each element, starting with the rect element.

SVG Rectangle - <rect>

Example 1

The <rect> element is used to create a rectangle and variations of a rectangle shape:

Here is the SVG code:

Example

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <rect width="300" height="100"
  style="fill:rgb(0,0,255);stroke-width:1;stroke:rgb(0,0,0)"/>
</svg>

Try it yourself »

For Opera users: View the SVG file (right-click on the SVG graphic to view the source).

Code explanation:

  • The width and height attributes of the rect element define the height and the width of the rectangle
  • The style attribute is used to define CSS properties
  • The CSS fill property defines the fill color of the rectangle
  • The CSS stroke-width property defines the width of the border of the rectangle
  • The CSS stroke property defines the color of the border of the rectangle

Example 2

Let's look at another example that contains some new attributes:

Here is the SVG code:

Example

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <rect x="50" y="20" width="150" height="150"
  style="fill:blue;stroke:pink;stroke-width:5;fill-opacity:0.1;
  stroke-opacity:0.9"/>
</svg>

Try it yourself »

For Opera users: View the SVG file (right-click on the SVG graphic to view the source).

Code explanation:

  • The x attribute defines the left position of the rectangle (e.g. x="50" places the rectangle 50 px from the left margin)
  • The y attribute defines the top position of the rectangle (e.g. y="20" places the rectangle 20 px from the top margin)
  • The CSS fill-opacity property defines the opacity of the fill color (legal range: 0 to 1)
  • The CSS stroke-opacity property defines the opacity of the stroke color (legal range: 0 to 1)

Example 3

Define the opacity for the whole element:

Here is the SVG code:

Example

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <rect x="50" y="20" width="150" height="150"
  style="fill:blue;stroke:pink;stroke-width:5;opacity:0.5"/>
</svg>

For Opera users: View the SVG file (right-click on the SVG graphic to view the source).

Code explanation:

  • The CSS opacity property defines the opacity value for the whole element (legal range: 0 to 1)

Example 4

Last example, create a rectangle with rounded corners:

Here is the SVG code:

Example

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <rect x="50" y="20" rx="20" ry="20" width="150" height="150"
  style="fill:red;stroke:black;stroke-width:5;opacity:0.5"/>
</svg>

Try it yourself »

For Opera users: View the SVG file (right-click on the SVG graphic to view the source).

Code explanation:
