SVG, the "Scalable Vector graphics" Scalable vector graphic, based on Extensible Markup Language, is used to describe a graphic format for two-dimensional vector graphics.

SVG is purely XML and can be inserted into HTML using the following methods:

    • Using <iframe> elements to embed SVG images
    • Using elements to embed SVG images
    • Embed an SVG image as a background image
    • Using <svg> elements directly
    • Using <embed> elements to embed SVG images
    • Using <object> elements to embed SVG images

Suppose you have an SVG file, named Test.svg, as shown below.

<?XML version= "1.0" encoding= "UTF-8"?><!DOCTYPE svg public '-//w3c//dtd svg 1.1//en ' http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd '><svgwidth= "$"Height= "$"xmlns= "Http://www.w3.org/2000/svg">//Here xmlns is necessary<rectwidth= "100%"Height= "100%"style= "Fill:cornflowerblue" /></svg>

The xmlns declaration space for SVG must be specified, otherwise it will not be parsed as an SVG tag.

Write an HTML file that reads as follows

<!DOCTYPE HTML><HTMLLang= "en"><Head>    <MetaCharSet= "UTF-8">    <title>Document</title></Head><Body>    <imgsrc= "Test.svg"></Body></HTML>

The results are as follows

You can also use SVG tags directly in the HTML5 document, as shown below

<!DOCTYPE HTML><HTMLLang= "en"><Head>    <MetaCharSet= "UTF-8">    <title>Document</title></Head><Body>    <svgwidth= "$"Height= "$">        <CircleCX= "+"Cy= "+"R= " the"style= "Fill:url (#orange_red)" />        <defs>            <lineargradientID= "Orange_red"X1= "0%"Y1= "0%"X2= "100%"y2= "0%">                <StopOffset= "20%"style= "Stop-color:rgb (255,255,0); Stop-opacity:1 "/>                <StopOffset= "80%"style= "Stop-color:rgb (255,0,0); Stop-opacity:1 "/>            </lineargradient>        </defs>    </svg></Body></HTML>

The performance is shown below
