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 width="400" height="110">
 
<rect width="300" height="100"
style="fill:rgb(0,0,255);stroke-width:3;stroke:rgb(0,0,0)" />
</svg>

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 for the rectangle
 - 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 width="400" height="180">
 
<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>

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 width="400" height="180">
 
<rect x="50" y="20" width="150" height="150"
 
style="fill:blue;stroke:pink;stroke-width:5;opacity:0.5" />
</svg>

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 width="400" height="180">
 
<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>
