Reference an svg embedded in html in html document in same folder - html

I would like to reference an svg embedded in one html document in another html document in the same folder. I don't need a fallback, but I would prefer one. I have seen: HTML - pick images of Root Folder from Sub-Folder, and How to link html pages in same or different folders?, and Do I use <img>, <object>, or <embed> for SVG files?.
I have one html document with the svg that I would like to reference here: (this document is called "pd_unit_red_fighter_v.0.0" and is located in the same folder)
<!doctype html>
<html>
<head>
<title>Title</title>
</head>
<body>
<svg id="red_fighter" width="480" height="480" viewBox="0 0 24 24">
<g stroke-width=".25" stroke="#000" fill="#ccc" >
<circle cx="12" cy="12" r="11.5" fill="#800" />
</g>
</svg>
</body>
</html>
I have another html document and I would like this document to reference the svg in the other one:
<!doctype html>
<html>
<head>
<title>test</title>
</head>
<body>
<object data="red_fighter.svg" type="image/svg+xml">
<img src="./pd_unit_red_fighter_v.0.0.html" />
<a href="#./pd_unit_red_fighter_v.0.0.html" >
<img class="logo" src="red_fighter.svg" width="240" height="240"/>
</a>
</object>
</body>
</html>
I have tried both the object tag and but I cannot get it to work. Is there another tag I should use or am I using the wrong information? I am new to this so I apologize for my lack of knowledge.

When you reference an SVG file using an object or image tag it must actually be an SVG file and not svg data embedded in an html file so you want red_fighter.svg to be
<svg xmlns="http://www.w3.org/2000/svg" id="red_fighter" width="480" height="480" viewBox="0 0 24 24">
<g stroke-width=".25" stroke="#000" fill="#ccc" >
<circle cx="12" cy="12" r="11.5" fill="#800" />
</g>
</svg>
Note the namespace attribute which is mandatory for standalone SVG files.
Then you can reference it using an object or img tag.
Take care that the svg file is served with the correct mime-type (try viewing it directly to check it works first).

svg external stylesheet not work

I am new svg learner and try to animate svg file with external style sheet but fail fail to style my object 'Cube'.
[index.html file]
<head>
<link rel="stylesheet" type="text/css" href="cube.css">
</head>
<body>
<img src="cube-motion.svg" height="350px" />

You are on the right track with the inclusion of the external stylesheet inside the SVG:
<?xml-stylesheet type="text/css" href="cube.css" ?>
The reason it doesn't work is because the SVG is loaded in the HTML as an <img> which - rightfully - does not allow additional external assets to be processed.
If you're adamant on having the CSS from an external file, you have two options, either embed the SVG inside the html or use <object data=file.svg type=image/xml+svg></object>.
Depending on your use case, you basically have three ways to use CSS for styling:
<img src="my.svg">
Images are not interactive and are not allowed to load any other assets within themselves. Simple presentation of the referenced image file only.
It does allow to use CSS, but only from a <style>-element inside the SVG.
<object data="my.svg" type="image/svg+xml"></object>
Objects can do more than images, such as loading additional assets and even include isolated (within the loaded SVG) interactions (e.g. the CSS :hover-pseudoclass)
Loading an external CSS file is done as you have it in the example code, the <?xml-stylesheet...?>-instruction goes before the <svg>-tag
<svg...>...</svg>
Fully embedded in the HTML document, this is allows for full integration within the page (this may have benefits on the interaction side and downsides on the CSS side, as you'll then have to take style isolation into consideration), but also the least re-usable as you'd basically have to repeat the entire SVG, which doesn't matter if used once on a page.
Note that in order to embed the SVG inside the HTML document, you cannot put any of the SVG doctype and/or xml declarations in the HTML (<?xml...?>, <!DOCTYPE svg...> and <?xml-stylesheet...?>).
With embedded SVG, you can simply import (or inline) the style using the usual HTML <link> or <style> nodes, where the <style> element may also still be inside the <svg>-element.
Here's a quick sample of the difference between <img> and <object>

How to move svg path out of html

I am using this example from Chris Coyer
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" mlns:xlink="http://www.w3.org/1999/xlink" style="display: none;">
<defs>
<g id="icon-image">
<path class="path1" d="M0 4v26h32v-26h-32zM30 28h-28v-22h28v22zM22 11c0-1.657 1.343-3 3-3s3 1.343 3 3c0 1.657-1.343 3-3 3-1.657 0-3-1.343-3-3zM28 26h-24l6-16 8 10 4-3z"></path>
</g>
</defs>
</svg>
<h1>
<svg viewBox="0 0 32 32">
<use xlink:href="#icon-phone"></use>
</svg>
Call me
However, I would like the path definitions to NOT be in the html as they will be used throughout the app.
Is this possible? (Note: I have read the answer that suggests javascript to manually inject the svg into the html. I don't want to do that either.)
I know there are many ways of embedding/linking SVG paths and files. And I have tried them all. In particular, I need to be able to style it to the currentColor. As covered in detail in this blog post, this cannot be done with external SVG files which are then used in an img tag.
So the closest thing I have found is this example above. However, I still don't want the path embedded in the html. If I could somehow get it in an external file of some type so it is reusable, that would be great.
Another option would be to convert SVG to a font
Searching the internet for "convert SVG to font" will give you a lot of sites/tools doing that, like:
https://icomoon.io/app/#/select
https://glyphter.com/
http://fontastic.me/
Also "HTML entities" have some reusable icons etc.
https://dev.w3.org/html5/html-author/charref
There's only one remaining option here. You don't want to embed the svg manually, you don't want to inject it with javascript and you don't want to use it in an img tag since you want to modify the properties with css. The only remaining solution would be to use your server-side language to inject it.
If you're using php, you can simply echo the content of your svg file where you want:
<?php echo file_get_contents(file_path); ?>
Another option I found is SVG Sprites, explained in detail by Chris Coyier
<!DOCTYPE html>
<html>
<head>
<title></title>
<meta charset="utf-8"/>
<style>
.icon {
width: 125px;
height: 125px;
background: #eee;
fill: currentColor;
}
body {
padding: 20px;
}
</style>
</head>
<body>
<div style="color: red">
<svg class="icon"><use xlink:href="menu.svg#beaker"/></svg>
</div>
<div style="color: brown">
<svg class="icon"><use xlink:href="menu.svg#fish" /></svg>
</div>
</body>
</html>
And then this in a separate file called menu.svg:
<?xml version="1.0" ?><!DOCTYPE svg PUBLIC '-//W3C//DTD SVG 1.1//EN' 'http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd'>

Eclipse gives warnings on inline svg tags/attributes

I have the following svg inlined in my html:
<div class="navigationItem">
<svg class="navigationItemIcon" viewBox="0 0 512 512">
<path d="M257.122,165....">
</svg>
</div>
The svg is displayed and styled correctly, but I get 2 errors in my editor (Eclipse Juno, Java EE perspective)
On the svg attribute viewbox=0 0 512 512 I get the error: "undefined attributename".
On the <path> tag i get the error: "undefined tag".
I think I need to import something to tell my editor these are valid normal tags, but I don't know:
what to import?
where to import it into (into the html file? into my project as a library? into my eclipse?)
what is the syntax for importing?
You need to import svg DTD :
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:svg="http://www.w3.org/2000/svg">
<head>
<meta charset="UTF-8" />
<title>Titre : First SVG</title>
</head>
<body>
<h1>Cercle SVG</h1>
<svg:svg width="100" height="100">
<svg:circle cx="50" cy="50" r="40" stroke="green" stroke-width="4" fill="yellow" />
Sorry, your browser does not support inline SVG.
</svg:svg>
</body>
</html>
I see two possible errors:
1) viewbox is viewBox
2) The path element is not closed i.e. />

Embedding SVG in HTML without a link

Ok, so I know how to place a static SVG into html:
<object data="your.svg" type="image/svg+xml">
<img src="yourfallback.jpg" />
</object>
But, how do I place the actual SVG document (eliminating the link to save an http request):
<object data='<path d="m315.9,581.1c.....1,22.8z" fill="#fff" stroke="#4ea3ff" stroke-miterlimit="10" stroke-width="36"></path>' type="image/svg+xml">
<img src="yourfallback.jpg" />
</object>
I can't seem to get it to work.
You can make a data URI of the svg if you want to keep using the object tag, see this answer for the details.
Just paste in the svg. But you'll need to start it with an <svg> tag though, you can't just use a raw <path>
<!DOCTYPE html>
<html>
<body>
<svg height="190">
<polygon points="100,10 40,180 190,60 10,60 160,180"
style="fill:lime;stroke:purple;stroke-width:5;fill-rule:evenodd;">
</svg>
</body>
</html>

Reuse objects defined in <defs>?

I wanted to write a logo in svg, but surprisingly found that I could not re-use objects defined in <defs>...</defs>. I tried them on Chrome.
Please see examples:
test1.html doesn't work, no rect was drawn.
<!DOCTTYPE html>
<html>
<body>
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
width="480" height="360">
<defs>
<rect id="helo" x="0" y="0" height="20" width="20" />
</defs>
<use xlink:href="#helo" />
</svg>
</body>
</html>
BUT test2.svg works.
<?xml version="1.0"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN"
"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
width="480" height="360">
<defs>
<rect id="helo" x="0" y="0" height="20" width="20" />
</defs>
<use xlink:href="#helo" />
</svg>
What's needed to make the test1.html work?
Many thanks:)
It seems that this is a bug in Webkit:
Importing external SVG (with WebKit)
https://bugs.webkit.org/show_bug.cgi?id=12499
If you're going to create an SVG icon, I would make it in a separate .svg file and then add it into the HTML with the object tag. That would be better anyway since if you make changes to the SVG file and it will change all instance on your website.
The bug seems to have been fixed now however there is one important caveat here that when you are trying to re-use objects in the defs tag in SVG on a HTML page the xmlns:xlink="http://www.w3.org/1999/xlink" is important and must be added to the SVG tag. Without that the href isn't resolved.
