1 <svgversion= "1.1"2 Baseprofile= "full"3 width= "+"Height= "$"4 xmlns= "Http://www.w3.org/2000/svg">5 6   <rectwidth= "100%"Height= "100%"Fill= "Red" />7 8   <CircleCX= "Max"Cy= "+"R= "a"Fill= "Green" />9 Ten   <textx= "Max"y= " the"font-size= "$"Text-anchor= "Middle"Fill= "White">Svg</text> One  A </svg>

Note: 1. The DOCTYPE declaration from (X) HTML should be discarded because SVG-based DTD validation can cause more problems than it solves. 2. versionAnd baseProfileattribute is required for other types of validation to determine SVG version 3, as a dialect of XML, SVG must have the correct binding namespace (in the xmlns attribute). SVG uses 1 in HTML, imports SVG as an image

<src= "Test.svg"  alt= "svg">

2. Background-image introduced in CSS

Background-image:url (TEST.SVG);

3. Import SVG images using object or IFRAME

<type= "Image/svg+xml"  data= "Test.svg"></ Object > <  src= "Test.svg"></iframe>

4. Import SVG as data URI

<src= "Data:image/svg+xml;base64,[data]>background:url (data:image/svg+xml; Base64,[data]); <object type= "image/svg+xml" data= "data:image/svg+xml;base64,[data]></ Object>

<!--with version, namespace, Baseprofile -<svgversion= "1.1"Baseprofile= "full"width= "+"Height= "$"xmlns= "Http://www.w3.org/2000/svg">    <rectwidth= "100%"Height= "100%"Fill= "Green" /></svg><!--Shorthand -<svgwidth= "+"Height= "$">    <rectwidth= "100%"Height= "100%"Fill= "Green" /></svg>
