SVG not fitting parent container, preserveAspectRatio not working as expected - html

I have an SVG that I expect to scale to the size of it's parent container. Let's say for argument sake the parent container is width: 10rem; height: 10rem;
What I expect is that the following:
preserveAspectRatio="xMidYMid meet" viewBox="0 0 100 100"
on the SVG would size the SVG to its parent container, and center it on the X- and Y- axis. That's not working, and I'm still trying to grok the magical workings of viewBox. For example, the smaller I make the numbers (the 2nd set of numbers), the larger the SVG is within the viewBox.
Here is a codepen:
https://codepen.io/mearleycf/pen/VxGyPZ
In the codepen I want the SVG to be centered vertically and horizontally and fill the available gray space.


Your image is half the size of the custom view window viewBox.
In order to enlarge the image in half, it is necessary to reduce the viewBox twice viewBox="0 0 50 50"

The first variant of the solution fulfills the conditions of the question, but is not adaptive.
In order for svg to change its size along with changing the size of the parent container, you must specify its width and height in percent

Now increasing, decreasing the percentage of width and height of the parent container .viewport will also exactly change the size ofSVG


Changing viewBox to viewBox="-3 0 50 50" fix it. I think you can not get equal width and height to fit svg to square div because it needs to keep proportions.

Why anchor tag does not take height and width of its containing element
(7 answers)
Closed 2 years ago.
I have a simple inline SVG:
<svg xmlns="http://www.w3.org/2000/svg" style="display: none;">
<symbol id="circle" viewBox="0 0 512 512">
<path d="M256 8C119 8 8 119 8 256s111 248 248 248 248-111 248-248S393 8 256 8z" />
</symbol>
</svg>
<svg class="icon"><use xlink:href="#circle" /></svg>
and some styling:
<style>
.icon{
fill: black;
height: 1.25em;
width: 1.25em;
display:inline-block;
}
a{
background:red
}
</style>
However in this example, the SVG dimensions are 19.38 x 19.38 (black circle), whereas the anchor is offset and 20 x 17.6 (red background):
Codepen.io example is here: https://codepen.io/alias51/pen/qBbBoNo.
This is the case whatever the wrapping element around the svg is (anchor, span, etc). What is going on?? How can I align the SVG and anchor so they are the same dimensions?

This is css for svg
{
width: 1.8rem;
height: 1.8rem;
}
I am trying to figure out why this space exists.
https://codepen.io/colton123/pen/qBEGwLL

Two things: Your icon is not a perfect square, and there is a gap in the icon itself on the right side.
First, with the <svg> set to 1.8rem (32px in CodePen) the <g> is 30x27px. If you changed the height and width of <svg> to 3rem (48px in CodePen) the <g> would be 45x40.5px. Since you are forcing <svg> into a square, there will be a gap.
Second, the width of <g> should match the width of <svg>, but it is always 93.75% of the width. This means there is a 6.25% gap in the icon itself.

Hello please see this and solve your issue of SVG. Thanks

Now control the width of the <svg> by adjusting the width of the wrapper.
As per why doesn't changing viewBox work, it's because the <svg> is a document, which has infinite size in theory, and the viewBox is just the window you watch this document through. <svg> is not an image. It's a document.
Ref: Why does it need a viewBox (in comments).
A: It needs a viewBox so you can define the size of what gets printed in your context in order to have control over it. If you have a viewBox and you use CSS to resize the <svg> you will transform what gets printed according to the ratio between viewBox and <svg> size. Without viewBox, you have no control over the contents of svg. It just gets printed the same size at all times, with a 1:1 ratio between svg units and document pixels, and the <svg> in your document acts as a viewBox. When bigger, you see all the contents, but they won't stretch to fit. When smaller, the contents will be cropped. Without viewBox you have no control over the size of the contents of <svg>. That's why you need a viewBox.

SVG's not inheriting values from parent

So this seems to be a bug that just cropped up in Chrome today (and Firefox apparently).
I have an SVG wrapped inside a span (I've tried div's and object tags as well, it doesn't seem to matter), and that span has a specified height and width. Yesterday, the child element would size itself appropriately to the full dimensions of it's parent, as every other html element does. However, now, that SVG element is not getting the inherited size from its parent, and is sizing itself based off the actual size of the SVG.
Check out the fiddle here: http://jsfiddle.net/theandybob/4LHeB/
The CSS:
.icon-small {
width: 32px;
height: 32px;
position: relative;
display: inline-block;
}
And the Code:
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<symbol id="run-import" viewBox="0 0 48 48">

</symbol>
</svg>
<span class="icon-small">
<svg><use xlink:href="#run-import"></use></svg>
</span>
Now, this happens in Chrome (both on Windows and Mac), and Firefox, but not IE or Safari. Ideas on how to fix the issue, or where it came up from?
The only workaround I have now is to specifically set the svg size to inherit from it's parent.
Also, throwing the version numbers out there:
1. Chrome: Version 36.0.1985.125 m
2. Firefox: 30.0

You need height and width on the <svg> element which you can set using CSS if you wish but which I've set using attributes.
