Responsive inline svg? - svg

This SVG icon is 640x640px. The toolbar is 48px high.
The icon should now automatically adjust to the height of the toolbar.
Accordingly, the blue area would have to be 48x48px.
However, the icon now occupies much more space than it needs.
I gave the svg a height of 48px. Better would be height: 100% but that does not work.
my codepen

Changing only the height to 48px leaves the width at 640px. Because you have width="640px" specified on your <SVG>.
So the fix is simply to remove the width and height attributes from <svg>.
body {
margin: 5%;
}
.toolbar {
position: realive;
color: #fff;
display: flex;
align-items:center;
justify-content: space-between;
background: red;
height: 48px;
}
.toolbar__section.flex-grow {
flex-grow: 1;
}
.toolbar__section.bg-green {
background: green;
}
svg {
display: flex;
height: 48px;
background: blue;
}

Delete the width attribute from the svg element. You may have to adjust the flex-grow attributes in your toolbar afterwards.

SVG - stroke-dasharray with percentage units doesn't work as expected

I think I don't quite understand something here.
Percentage units in stroke-dasharray are realtive to what? I was thinking relative to the SVG viewbox, but I was probably wrong.
My problem:
I have an SVG with the width of 320px and the height of 160px.
In this SVG I draw a line from x1 = "0%" to x2 = "100%", so it has a width of 320px just like the SVG.
Then I give the line: stroke-dasharray: 100% 100%;
For me it is surprising that the line is not drawn with the full width of the SVG, but only about 80%.

If someone has an idea, I would be happy to hear from you
Here the link to an example: https://codepen.io/stefka1210/pen/xxVwBom
html, body {
width: 100%;
height: 100%;
}
body {
display: flex;
align-items: center;
justify-content: center;
}
.container {
width: 320px;
height: 160px;
background: lightgrey;
}
svg {
width: 100%;
height: 100%;
}
line {
stroke-width: 2px;
}
#one {
stroke-dasharray: 100% 100%;
stroke: red;
}
#two {
stroke-dasharray: 320px 320px;
stroke: green;
}
<html>
<body>
<div class="container">
<svg x="0px" y="0px" viewBox="0 0 320 160" xmlns="http://www.w3.org/2000/svg">
<g>
<line id="one" x1="0%" y1="40%" x2="100%" y2="40%"></line>
<line id="two" x1="0%" y1="60%" x2="100%" y2="60%"></line>
</g>
</svg>
</div>
</body>
</html>
Since a line can go in any direction, it would not make sense to link "percentage of the viewport" to either its width or height. Instead, 100% is set to the root mean square of width and height:
For width = 320 and height = 160, that gives a length of 252.98.

Clip-Path vs Border-Radius issue when window is resized

I want to use an SVG as a clip-path to round the edges of an image. Yes, I must do it in this way for various reasons .
PROBLEM:
When the browser window is resized, the points and handles that form the rounded corners adjust to the changing size of the image (bounding box) because I'm using clipPathUnits="ObjectBoundingBox". This causes the rounded edges to loose their "roundness" and look overall really bad. The CSS border-radius property doesn't have this issue. No matter how you resize the browser window, the edges of a div clipped with border-radius never loose their round shape. The problem is most apparent when you resize the browser window to it's most narrow or widest possible state. Try that with this codepen and you'll see what I mean. The top image uses border-radius and the bottom image uses clip-path. Is there any way to force the ONLY rounded edges of the SVG clip-path to stay equally rounded no matter how the image is resized without sacrificing the responsiveness of the clip-path dimensions? Is this even possible? I'm totally open to a JavaScript solution if there is one. Thanks!
You can trick the <svg> element to have just the same dimensions as the image and then size the clip-path with relative units. The downside is that you cannot reuse these paths but have to define one for every individual image.
.box {
left: 5%;
height: 40%;
position: absolute;
background-color: blue;
overflow: hidden;
}
#box1 {
top: 5%;
width: 50%;
clip-path: url(#clipPath1);
}
#box2 {
top: 55%;
width: 90%;
clip-path: url(#clipPath2);
}
.flower{
width: 100%;
height: 100%;
object-fit: cover;
object-position: center;
}

width: 100%;

svg image not working in safari 5.1.7 (windows)

svg image not working in safari 5.1.7 (windows) . But when i open the svg image in safari and then visit the site, the image is displayed there.
Safari on Windows has known issues calculating the height of responsive inline SVGs.
You might try the intrinsic ratio technique, whereby you position the <svg> tag absolutely inside an <object> tag with bottom padding equal to the ratio of the viewBox (or height/width attributes) of the svg.
.my-responsive-svg {
width: 100%;
display: block;
height: auto;
position: relative;
/* for an svg with a 16:9 aspect ratio */
padding-top: 56.25%;
}
.my-responsive-svg svg {
width: 100%;
height: 100%;
position: absolute;
top: 0;
left: 0;
right: 0;
}
<object class="my-responsive-svg">
<svg width="160" height="90" viewBox="0 0 160 90">
<rect x="10" y="10" width="140" height="70" />
</svg>
</object>

Show scrollbars if SVG elements overflows their container

I have an embedded SVG with dynamic content inside, which may grow in all directions.
This content may be grow bigger than the fix sized container around.
My expected behavoir is, to show scrollbars, if any element inside the SVG needs more place than the container provides.
See the following simplified example:
<html>
<head>
</head>
<body>
<div style="overflow: auto; position: absolute; top: 60px; left: 60px; background-color: gray; height: 200px; width: 300px;">
<svg style="height: 190px;">
<rect x="-50" y="0" width="100" height="50" fill="red"></rect>
</svg>
</div>
</body>
</html>
What is the way to do this?
Is it really true, there is no concept in SVG to support such behavoir?
Any suggestions how to do it right "by hand"?
Svg does'nt support auto resizing to inside elements of itself.
So, you should resize manually the svg graphic to be able to scroll by outer svg element.
var svg = document.querySelector("svg");
var bbox = svg.getBBox();
svg.setAttribute("viewBox", [bbox.x, bbox.y, bbox.width, bbox.height]);
svg.width.baseVal.valueAsString = bbox.width;
svg.height.baseVal.valueAsString = bbox.height;

SVG scales down to fit small screen height, why?

I have a simple SVG in a web page, and I'd like the SVG to be responsive to width only. The problem is, it scales down also when the screen height is less than the SVG height.
HTML:
<div class="container">
<svg version="1.1" width="100%" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 500 500" preserveAspectRatio="xMinYMin">
<circle stroke="#000" stroke-width="10" fill="transparent" cx="250" cy="250" r="200"/>
</svg>
</div>
CSS:
svg {
max-height: 100%;
}
.container {
width:50%;
border: 1px solid black;
}
Here is the jsfiddle, where you can see the circle radius decreases when the window height is reduced. How can this be avoided ?
Thanks !
Here is what I wanted to achieve, sorry if my question wasn't clear enough:
width of the SVG depending only on the width left available to the container,
(width / height) ratio of the SVG preserved at all time,
container's height depending only on the width of the SVG and its (width / height) ratio.
I got it working this way:
HTML & SVG:
<div class="container">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg"
viewBox="0 0 500 400" preserveAspectRatio="xMinYMin">
<circle fill="#F7941E" stroke="#231F20" stroke-width="10" cx="250" cy="200" r="150"/>
</svg>
</div>
<hr>
CSS:
.container {
position: relative;
width:50%;
padding-bottom: 40%;
border: 1px solid black;
}
svg {
position: absolute;
top: 0;
left: 0;
max-height: 100%;
}
Fiddle here
The only drawback I see is that the padding-bottom of the container needs to be defined, and to a value matching the w/h ratio of the SVG, which is redundant.
If what you want is for the circle to remain the same size even when the window size changes, then just get rid of the viewBox. Try removing : viewBox="0 0 500 500" preserveAspectRatio="xMinYMin" from the opening svg tag.
The default for height (like width) is 100%. Which means 100% of it's container height.
One solution is to give the container a very large height.
.container {
width:50%;
height: 9999px;
border: 1px solid black;
}
Fiddle here
You don't really say what you want to happen to the lower parts of the circle when the height scales up. If you want it to be hidden off the bottom of the div container, then you could do something like this:
svg {
height: 9999px;
}
.container {
width:50%;
height: 300px;
overflow: hidden;
border: 1px solid black;
}
