HTML - <svg> Tag

In order to contain SVG graphics, we use the <svg> tag. A modular language called HTML SVG is used to describe visuals in XML. It describes mixed vector and two-dimensional vector graphics in XML. The W3C has recommended it.

XML text files are used to define SVG images and their behaviors. An SVG image can therefore be created and edited as XML files, but generally speaking, drawing program like inkspace are preferred to generate it. SVG is mostly used for vector diagrams, such as pie charts and 2-D graphs with an X, Y coordinate system etc.

Syntax

Following is the syntax of the <svg> tag −

<svg>
......
</svg>

Specific Attributes

The HTML <svg> tag also supports the following additional attributes −

S.No. Attribute & Description

3

contentStyleType

Specifies the SVGfragment's default style sheet language.
4

Indicates the vertical length of rect.
5

preserveAspectRatio

Specifies the required deformation of the SVG fragment when it is inserted into a container with a different aspect ratio.
6

version

specifies the SVG version that was used to create the element's inner content.
7

viewbox

For the current SVG fragment, defines the bounds of the SVG viewport.
8

width

Example

Let’s look at the following example, where we are going to draw a rectangle using the <svg> tag.

<!DOCTYPE html>
<html>
<body>
   <svg width="250" height="150">
      <rect width="200" height="100" style="fill:#DE3163;
         stroke-width:8;stroke:#D5F5E3" />
   </svg>
</body>
</html>

On running the above code, it will generate an output consisting of a rectangle drawn on the webpage.

Example

Considering another scenario where we are going to draw a square with round corners.

<!DOCTYPE html>
<html>
<body>
   <svg width="400" height="400">
      <rect x="25" y="25" rx="20" ry="20" width="200" height="200" style="fill:#58D68D;stroke:#7D3C98;stroke-width:3;opacity:0.5" />
   </svg>
</body>
</html>

When we execute the above code, the output window will pop up, displaying the square drawn with round corners displayed on the webpage.

Example

Following is the example, where we are going to draw the SVG logo.

<!DOCTYPE html>
<html>
<body>
   <svg height="200" width="600">
      <defs>
         <linearGradient id="tutorial" x1="1%" y1="1%" x2="50%" y2="1%">
            <stop offset="0%" style="stop-color:white;
               stop-opacity: 1" />
            <stop offset="100%" style="stop-color: #52BE80;
               stop-opacity: 1" />
         </linearGradient>
      </defs>
      <ellipse cx="210" cy="100" rx="120" ry="81" fill="url(#tutorial)" />
      <text fill="#17202A" font-size="20" font-family="verdana" x="121" y="111"> TUTORIALSPOINT </text>
   </svg>
</body>
</html>

On running the above code, it will generate an output consisting of the SVG logo displayed on the webpage.
