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>



.

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>




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



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>
