SVG rectangle

SVG Shapes

SVG has some predefined shape elements, can be used by developers to use and operate:

  • Rectangle <rect>
  • Round <circle>
  • Oval <ellipse>
  • Line <line>
  • Polyline <polyline>
  • Polygon <polygon>
  • Path <path>

The following sections will explain to you these elements, starting from a rectangular element.


SVG rectangle - <rect>

Example 1

<Rect> tag is used to create a rectangle, and a rectangular variant:

Here is the SVG Code:

Examples

<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"

For Opera users: view SVG file (right-click on the preview source SVG graphics).

Code analysis:

  • width and height attributes rect elements define the height and width of the rectangle
  • style property is used to define CSS properties
  • CSS fill property defines the rectangle fill color (rgb values, color name or hexadecimal value)
  • Width of stroke-width CSS property defines the rectangular border
  • The stroke color CSS property defines the rectangular border

Example 2

Let's look at another example, it contains a number of new properties:

Here is the SVG code:

Examples

<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"

For Opera users: view SVG file (right-click on the preview source SVG graphics).

Code analysis:

  • X attribute defines the left position of the rectangle (for example, x = "0" to define the rectangle to the left side of the browser window, the distance is 0px)
  • Top position y attribute defines the rectangle (for example, y = "0" from the definition of the rectangle to the top of the browser window is 0px)
  • CSS's fill-opacity property defines the transparency of the fill color (legal range: 0--1)
  • The CSS stroke-opacity property defines the transparency of the stroke color (legal range: 0--1)

Example 3

Define the opacity of the entire element:

Here is the SVG Code:

Examples

<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>

try it"

For Opera users: view SVG file (right-click on the preview source SVG graphics).

  • CSS opacity property defines the value of the transparent element (range: 0-1).

Example 4

The last example, create a rounded rectangle:

Here is the SVG Code:

Examples

<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"

For Opera users: view SVG file (right-click on the preview source SVG graphics).

  • rx and ry attributes can generate rounded rectangle.
