Viewbox changing width of element - svg

Would somebody be able to explain to me why adding viewBox="0 0 612 100" in the snippet below changes the width of the embedded rectangle? Based on everything I know about viewbox if the numbers match the user units of the SVG, no zooming or panning should be done, and thus the size of the two rectangles should be the same.
<div>
<svg width='612pt' height='100pt' xmlns="http://www.w3.org/2000/svg">
<rect width="100pt" height="100pt" />
</svg>
</div>
<div>
<svg width='612pt' height='100pt' viewBox="0 0 612 100" xmlns="http://www.w3.org/2000/svg">
<rect width="100pt" height="100pt"/>
</svg>
</div>

Your viewbox is measured in pixels (px - also the default unit in SVG), while you have measured the other widths/heights in points (pt).
Point vs Pixel: What is the difference?
Use pixels all over, and things will work the way you expect:
<svg width="200" height="150" viewBox="0 0 200 150" xmlns="http://www.w3.org/2000/svg">
<rect width="100%" height="100%" fill="pink"/>
<rect width="100pt" height="100pt" fill="red"/>
<rect width="100" height="100" fill="green"/>
</svg>

Responsive full width svg logo

So I have this logo that fits the whole page. Is there anyway that, when the browser is resized I can move these paths? That way the height stays the same?
Example of what I want to achieve
Here's my svg code
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"

</svg>
you can do something like this by using preserveAspectRatio="none" for the svg element together with a fixed height and width:100%. This would give tou what you need but the the stroke would be scaled differently on the vertical and horizontal.
To fix it you need to add vector-effect="non-scaling-stroke" for the path.
svg{height:100px; width:100%}
<svg viewBox="0 0 100 20" preserveAspectRatio="none">
<path stroke="black" stroke-width="5" vector-effect="non-scaling-stroke" d="M 1,5V15M1,10H97"/>
</svg>
Yes it is possible, with a bit of trickery. Below is a modified verion of your SVG that behaves how you want.
This matches your SVG exactly, but has a limitation. The trick we are using relies on extending the middle bar a long way to the left. Then covering up the left end of the bar with your vertical piece. But in your original SVG the vertical piece is not right at the left end of your SVG. So I've had to hide some of the extension with a white rectangle. This assumes your background will also be white. If it isn't you'll need to change that white rectangle to be the same colour as your page background.

</svg>
If you want to get a better idea how the trick works, have a look at this version. I've modified the SVG to make the trick more apparent.
svg {
background-color: red;
overflow: visible;
}
rect {
opacity: 0.5;
}
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="52">

</svg>
However if you don't mind the vertical piece on the left end being moved so it's hard up against the left side of the SVG, then we can remove that restriction regarding the background. The new version below will work for any page background colour.

Two SVGs combined together

I have two SVG's. One just draws a grey circle, the second is a dog paw print. I'm really not good with SVGs and have no idea about combining the two so that the paw print is inside the circle. I have tried various approaches, the circle remains however the paw print is either hidden or just not shown.

The solution to your problem is using the paw as a symbol. For the symbol you need to use the same viewBox as the original svg element: viewBox="0 0 551.062 551.062" in this case. Now you can use the symbol and you can give the use element the position (x,y) and the size (width, height) you want.

how to do svg transform in percentage

I want to center the rect shape with something equivalent to
transform="translate(50% - 100,0)" for example:
<svg width="100%" height="100%" viewbox="0 0 100% 100%">
<g transform="translate(50% - 100,0)">
<rect width="200" height="100" fill="rgb(0,0,255)" />
</g>
</svg>
I can't find the right syntax.
You can use an inner <svg> element to do the percentage part via its x attribute then the rest with the <g> element as you already have.
I'm not sure what you intend with the viewBox but percentage values are not valid there. Looks like you just don't need that at all.
<svg width="100%" height="100%">
<svg x="50%" overflow="visible">
<g transform="translate(-100,0)">
<rect width="200" height="100" fill="rgb(0,0,255)" />
</g>
</svg>

I'd appreciate it if someone could point out my issue.
ALSO - I would like to know how and where to include a stroke color & width in this html. Thanks!!
I think there are a couple of problems with the first SVG:
The viewBox is incorrect. It doesn't match the shape. It should be more like:
viewBox="227.125 154.881 0.007 0.005"
The first two values (minX and minY) were wrong. How did this happen? I don't know. The code in that question looks alright at first glance, but I haven't attempted to debug it.
Secondly, I think there is likely a floating point issue. There are five orders of magnitude difference between the x and y offset of the shape, and its size. It seems you may be striking some floating point rounding issues, or something like that.
If you reduce the x and y coordinates, the shape renders correctly.

To avoid this problem with other shapes, you could modify the code to subtract the minX and minY value from all the coordinates. After you fix issue #1, though, of course!
The first SVG is located outside the drawing area/viewBox, however You can add the stroke inside the <g> tag that wraps the graphic, as in the second SVG theres two shapes and I added stroke to one only.
Check this code:

An SVG having only definitions for another scaling SVG still needs to scale?

My SVG is width="1200" height="600" viewBox="0 0 1200 600". It uses a clipPath from defs of another SVG.
<svg class="svg-def">
<defs>
<clipPath id="clip-1"> ...
</defs>
</svg>
<svg width="1200" height="600" viewBox="0 0 1200 600">
<g clip-path="url(#clip-1)">
...
</g>
</svg>
Demo
When .svg-def does not have width="1200" height="600" viewBox="0 0 1200 600" (the first image), on window width narrower than 1200, the right side is clipped. This is not desired.
I want the second image -- the clip is just the size of the SVG. The second image is good because the <clipPath> being used is from an <svg> element with the same width="1200" height="600" viewBox="0 0 1200 600"
<svg class="svg-def">
<defs>
<clipPath id="clip-1"> ...
</defs>
</svg>
<svg class="svg-def" width="1200" height="600" viewBox="0 0 1200 600">
<defs>
<clipPath id="clip-2"> ...
</defs>
</svg>
Questions
1) In <clipPath> <rect width="100%" height="100%"/>, what is 100% relative to?
2) The first clip's display width varies with window width (when the latter is narrow than 1200px). Narrower window width = narrower display width. What is the display width relative to?
3) So if I have an SVG which has only <defs>, its <svg> tag still has to have viewbox values, so that the other SVG which uses the definitions (and which scales with window width) can have definitions in correct sizes?
