Mobile Safari SVG Problem
I'm trying to get an SVG image to show up on my iPhone (or iPad) default browser, but I can't seem to get even just a rect to show up.
Example at: http://www.invalidpage.com/svg/svgtest.html
Source:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/html1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us">
<head>
<title>SVG iPhone Test</title>
</head>
<body>
<div>
<svg width="500" height="220">
<rect x="2" y="2" width="496" height="216" stroke="#000" stroke-width="2px" fill="transparent"></rect>
</svg>
</div>
</body>
</html>
Answer
Add xmlns="http://www.w3.org/2000/svg" version="1.1" to your svg tag.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/html1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-us">
<head>
<title>SVG iPhone Test</title>
</head>
<body >
<svg width="500" height="220" xmlns="http://www.w3.org/2000/svg" version="1.1">
<rect x="2" y="2" width="496" height="216" stroke="#000" stroke-width="2px" fill="transparent"></rect>
</svg>
</body>
</html>
The HTTP MIME type being delivered by http://www.invalidpage.com/svg/svgtest.html is
"Content-Type: text/html". HTML inline svg works with the MIME type "Content-Type: text/xml" You can create this by ending the document with XML instead of HTML as they have done here.
Not sure if Ipad cares about the Content-Type but other browsers do.
Updated
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
Can also be used; It is what is being shown on the Ipad svg examples. When the document is delivering as an XML not HTML, it should start with <xml version="1.0" standalone="no">;
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg width="500" height="220" xmlns="http://www.w3.org/2000/svg" version="1.1">
<rect x="2" y="2" width="496" height="216" stroke="#000" stroke-width="2px" fill="transparent"></rect>
</svg>
