how to position svg which is nested and contained in parent svg - javascript

i'm working on svg in html and added some nested svg in the webpage. how can I position the child svg contents which are present in a parent svg? the x and y coordinate is not working. and also tried translate but it is not working. I want to give values in cm (I don't know how to do it), but values in px also not working. is there a way to position svgs relative to one another? or if not possible, how can I translate or position it manually?
The code is in sniplet, kindly check it out

You can use x and y attributes to position nested <svg> elements. For example:
<!-- body -->
<svg width="100%" height="20.6cm" x="0" y="5.8cm">
In the example below I have used this method to position the body svg. I also made it red here so it is obvious which one it is.
<svg width="33.5cm" height="57.5cm" style="border:1px solid black;">
<svg width="31.8cm" height="54cm" x="1cm" y="2cm" style="border:1px solid black;">
<rect width="100%" height="100%" style="stroke:black; stroke-width:1; fill:none;"/>
<!-- Header -->
<svg width="100%" height="5.8cm">
<rect width="100%" height="100%" style="stroke:black; stroke-width:1; fill:none;"/>
<!-- Logo -->
<svg width="23.6cm" height="100%">
<rect width="100%" height="100%" style="stroke:black; stroke-width:1; fill:none;"/>
</svg>
</svg>
<!-- body -->
<svg width="100%" height="20.6cm" x="0" y="5.8cm">
<rect width="100%" height="100%" style="stroke:black; stroke-width:3; fill:red;"/>
</svg>
<!-- Ad -->
<svg width="100%" height="26.8cm">
<rect width="100%" height="100%" style="stroke:black; stroke-width:1; fill:none;"/>
</svg>
</svg>
</svg>
Note Be aware that a "cm" in SVG units will almost certainly not correspond to a real-world cm - for example on screen or printed. SVG units like "cm" and "in" are based on a standard CSS DPI of 96 CSS pixels per inch. No attempt is made to match the real DPI of the device that the SVG is being rendered on.

External SVG file in clippath

I have SVG file that i created it in photoshop. I would like to use it in my html page with clip-path property. I am trying to implement it as using clip-path:url(#mysvg); and paste the svg code to my html page. But i does not work. How can i do that?
My purpose is like this with css:
Here is the .svg file:
https://svgshare.com/i/dfw.svg
Here is the svg code
<!--IMAGE-->
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 814 506" >
<image id="image" class="image__svg-image" width="100%" height="100%" clip-path="url(#mask)" x="-100px" xlink:href="https://res.cloudinary.com/alvarosaburido/image/upload/v1589435086/blog/The%20Magic%20of%20SVG%20Clip-path/pic_yo5eyq.png" />
</svg>
<!--MY SVG FILE-->
<svg xmlns="http://www.w3.org/2000/svg" width="1920" height="1920" viewBox="0 0 1920 1920">

}
</style>
</defs>
<path id="rect1" class="cls-1" d="M133,333.637L1426.05,171.265a157.557,157.557,0,0,1,175.99,136.647l157.93,1256.5L466.929,1726.79a157.574,157.574,0,0,1-176-136.65Z"/>
</svg>
In this example the viewBox of the <svg> is 100 in width and the image also takes up 100% of the width. So, no matter the actual width of the image it will always fill the entire SVG.
The <clipPath> fits in the size of the viewBox of the <svg> that holds the image. I know the width is 100, so I made the clippath 70 in height and width plus the extra height that the rotation takes up. This matches kind of the height of the images (unknown at this point).
I replaced the content of the <clipPath>. It is more "transparent" what the clip path does and easier to manipulate.
<!--IMAGE-->
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 100 100" width="300">
<image width="100%" href="https://res.cloudinary.com/alvarosaburido/image/upload/v1589435086/blog/The%20Magic%20of%20SVG%20Clip-path/pic_yo5eyq.png" clip-path="url(#mask)" />
</svg>
<!--MY SVG FILE-->
<svg xmlns="http://www.w3.org/2000/svg" width="0" height="0">
<defs>
<clipPath id="mask" transform="translate(15 0) rotate(-10 60 0)">
<rect width="50" height="50" />
<rect x="20" y="20" width="50" height="50" />
<rect x="20" width="50" height="50" rx="10" />
<rect y="20" width="50" height="50" rx="10" />
</clipPath>
</defs>
</svg>
Update
OP asks if the original path can be used as a clip-path. It can, but the viewBox needs to be modified accordingly. So, if the viewbox 0 0 2300 1800 is used the path fits the image.
<!--IMAGE-->
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 2300 1800" width="300">
<image width="100%" href="https://res.cloudinary.com/alvarosaburido/image/upload/v1589435086/blog/The%20Magic%20of%20SVG%20Clip-path/pic_yo5eyq.png" clip-path="url(#mask)" />
</svg>
<!--MY SVG FILE-->
<svg xmlns="http://www.w3.org/2000/svg" width="0" height="0">
<defs>
<clipPath id="mask" transform="translate(350 0)">
<path id="rect1" class="cls-1" d="M133,333.637L1426.05,171.265a157.557,157.557,0,0,1,175.99,136.647l157.93,1256.5L466.929,1726.79a157.574,157.574,0,0,1-176-136.65Z"/>
</clipPath>
</defs>
</svg>
Update
To "path" or not to "path", that is the question. This third example is a better solution. The path is simpler and there are not that many child elements in <clipPath>.
<!--IMAGE-->
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 11 11" width="300">
<image width="100%" href="https://res.cloudinary.com/alvarosaburido/image/upload/v1589435086/blog/The%20Magic%20of%20SVG%20Clip-path/pic_yo5eyq.png" clip-path="url(#mask)" />
</svg>
<!--MY SVG FILE-->
<svg xmlns="http://www.w3.org/2000/svg" width="0" height="0">
<defs>
<clipPath id="mask" transform="translate(2 0) rotate(-10 7 0)">
<path d="M 0 0 L 6 0 A 1 1 90 0 1 7 1 L 7 7 L 1 7 A 1 1 90 0 1 0 6 Z"/>
</clipPath>
</defs>
</svg>
Update
This fourth example is using the original path, BUT defined in a <clipPath> and used as an external reference in CSS. The external SVG file have the following content:
<svg xmlns="http://www.w3.org/2000/svg">
<defs>
<clipPath id="mask" transform="translate(350 0)">
<path id="rect1" class="cls-1" d="M133,333.637L1426.05,171.265a157.557,157.557,0,0,1,175.99,136.647l157.93,1256.5L466.929,1726.79a157.574,157.574,0,0,1-176-136.65Z"/>
</clipPath>
</defs>
</svg>
But for this example I replace the URL (like https://svgshare.com/i/dfw.svg#rect) to the SVG file with a data URI.
svg>image {
clip-path: url('data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPgogIDxkZWZzPgogICAgPGNsaXBQYXRoIGlkPSJtYXNrIiB0cmFuc2Zvcm09InRyYW5zbGF0ZSgzNTAgMCkiPgogICAgICA8cGF0aCBpZD0icmVjdDEiIGNsYXNzPSJjbHMtMSIgZD0iTTEzMywzMzMuNjM3TDE0MjYuMDUsMTcxLjI2NWExNTcuNTU3LDE1Ny41NTcsMCwwLDEsMTc1Ljk5LDEzNi42NDdsMTU3LjkzLDEyNTYuNUw0NjYuOTI5LDE3MjYuNzlhMTU3LjU3NCwxNTcuNTc0LDAsMCwxLTE3Ni0xMzYuNjVaIi8+CiAgICA8L2NsaXBQYXRoPgogIDwvZGVmcz4KPC9zdmc+#mask');

ForeignObject in an SVG doesn't work - React

I'm trying to display a React component inside of an SVG. I used the foreignObject component to display my React object (ToolbarItem) inside of the SVG. However, nothing is displayed. What I did wrong?
Thanks for your help
<svg xmlns="http://www.w3.org/2000/svg" width="222.002" height="119.151" viewBox="0 0 222.002 119.151">
<g id="Margin" transform="translate(-51 -59)">
<path id="Soustraction_10" data-name="Soustraction 10" d="M10914,6398.1h0l-39-38.132v-41.828l39-38.139Z" transform="translate(-10641 -6220.475)" fill="#313c57">
<foreignObject x="40" y="40" width="100" height="100">
<ToolbarItem propKey="marginTop" type='draggableNumber' max={maxTop} />
</foreignObject>
</path>
</g>
</svg>
You can add a body tag
<foreignObject x="40" y="40" width="100" height="100">
<body>
<ToolbarItem propKey="marginTop" type='draggableNumber' max={maxTop} />
</body>
</foreignObject>
EDIT: the above works but generates a warning message.
Do the following instead :
<foreignObject x="40" y="40" width="100" height="100">
<div data-xmlns="http://www.w3.org/1999/xhtml">
<ToolbarItem propKey="marginTop" type='draggableNumber' max={maxTop} />
</div>
</foreignObject>

cannot change height of a svg group element with javascript

<svg>
<!--SOME SVG CODE HERE-->
<g id="bg"> <!--More svg code-->
</g>
</svg>
<!--Imports-->
<script src="script.js"></script>
<link rel="stylesheet" href="st.css">
</html>
CSS:
#bg{
height:100%;
}
When i use javascript to change the height:
document.getElementById("bg").style.height = "500px"
nothing happens, and, when i try to print the height in screen, it's returns nothing:
alert(document.getElementById("bg").style.height)
what can i do to change the height with javascript.
if you need to give a width and a height to an element inside an svg element you have to use a <symbol> with a viewBox instead of a group. Next you have to use the <symbol>and you can give a width and a height to the <use> element
svg{border:solid}
<svg viewBox="0 0 200 100" width="300">
<symbol id="c" viewBox="0 0 20 20">
<circle cx="10" cy="10" r="5"/>
</symbol>
<use xlink:href="#c" x="10" y="10" width="40" height="40" />
</svg>

How to pack text inside svg rect

I wish to fit svg text inside a rect. I could use an approach to compare the widths and add line breaks to the text, but it's not tedious.
Is there a more elegant way than this? Maybe by using CSS or d3?
UPDATE:the following code appends foreignObject using d3 but the div is not displayed. (it is there in the code inspecter)
var group = d3.select("#package");
var fo = group.append("foreignObject").attr("x", 15).attr("y", 15).attr("width", 190).attr("height", 90);
fo.append("div").attr("xmlns", "http://www.w3.org/1999/xhtml").attr("style", "width:190px; height:90px; overflow-y:auto").text("Thiggfis the dgdexsgsggs wish to fit insidegssgsgs");
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.11/d3.min.js"></script>
<p id="p"></p>
<svg width="220" height="120" viewBox="0 0 220 120" id="package">
<rect x="10" y="10" width="200" height="100" fill="none" stroke="black"/>
</svg>
A namespace cannot be assigned by attr, it's a side effect of element creation. You need an html div so you need to tell d3 that by calling the element xhtml:div, once you do that, d3 will do the rest.
var group = d3.select("#package");
var fo = group.append("foreignObject").attr("x", 15).attr("y", 15).attr("width", 190).attr("height", 90);
fo.append("xhtml:div").attr("style", "width:190px; height:90px; overflow-y:auto").text("Thiggfis the dgdexsgsggs wish to fit insidegssgsgs");
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/3.4.11/d3.min.js"></script>
<p id="p"></p>
<svg width="220" height="120" viewBox="0 0 220 120" id="package">
<rect x="10" y="10" width="200" height="100" fill="none" stroke="black"/>
</svg>
Here's a simple example of a foreignObject used to insert HTML markup into an SVG:
<svg width="220" height="120" viewBox="0 0 220 120">
<rect x="10" y="10" width="200" height="100" fill="none" stroke="black" />
<foreignObject x="15" y="15" width="190" height="90">
<div xmlns="http://www.w3.org/1999/xhtml" style="width:190px; height:90px; overflow-y:auto"><b>This</b> is the <i>text</i> I wish to fit inside <code>rect</code></div>
</foreignObject>
</svg>

Is there a way to sprite raster images within an SVG element?

I have the following SVG elements containing markers to be displayed on a map in a web page. The markers are composed of the <image> elements referencing to various small PNG images:
<svg id="OL_105_svgRoot" width="1246" height="373" viewBox="0 0 1246 373">
<g id="OL_105_root" style="visibility: visible;" transform="">
<g id="OL_vroot">
<image id="P115" cx="843" cy="203" r="1" x="827" y="188" width="32" height="32" href="spider.png" ...>
<image id="P119" cx="453" cy="269" r="1" x="437" y="254" width="32" height="32" href="zoo.png" ...>
<image id="P123" cx="628" cy="82" r="1" x="612" y="67" width="32" height="32" href="wild.png" ...>
<image id="P131" cx="10495" cy="69" r="1" x="1034" y="53" width="32" height="32" href="export.png" ...>
...
</g>
</g>
</svg>
Is there any way I can replace those images with a single large image file and use something similar to CSS background-position property to specify the viewing window for each image?
Wrapping the <image> elements into inner <svg> elements, specifying a certain width and height on the <svg> element and the "background-position" on the <image> element using the x and y attributes might be a solution:
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%">
<svg width="17" height="19">
<image xlink:href="http://s14.postimage.org/f66u116ap/rainbow_Hello_World4.png" width="188" height="19"/>
</svg>
<svg width="17" height="19" x="12" y="19">
<image xlink:href="http://s14.postimage.org/f66u116ap/rainbow_Hello_World4.png" width="188" height="19" x="-17"/>
</svg>
<svg width="17" height="19" x="35" y="6">
<image xlink:href="http://s14.postimage.org/f66u116ap/rainbow_Hello_World4.png" width="188" height="19" x="-34"/>
</svg>
<svg width="17" height="19" x="46" y="14">
<image xlink:href="http://s14.postimage.org/f66u116ap/rainbow_Hello_World4.png" width="188" height="19" x="-51"/>
</svg>
<svg width="17" height="19" x="60" y="24">
<image xlink:href="http://s14.postimage.org/f66u116ap/rainbow_Hello_World4.png" width="188" height="19" x="-68"/>
</svg>
</svg>
(See a test on Tinkerbin.)
You could also use the clip-path attribute, but I guess this is even more tedious than the above solution.
