I've been trying out using SVGs on a few of the latest projects, and since it scales, I was wondering what's your take on dynamic height and width of these SVGs?
So far, I've exported graphics from Illustrator, saving them as SVGs, opened the SVG and removed the doctype and #layer_1 etc IDs. And then I've edited the height and width attributes to 100%. So I've adjusted the size of the SVG by setting width and/or padding on their parent. This makes it easy to adjust the size with media queries. As well as CSS transitions. But I'm not sure this is the best way of doing it.
My HTML has been like this:
<div class="svg icon_phone">
<img src="static/icon_phone.svg">
</div>
<div class="svg">
<img src="static/icon_other.svg">
</div>
CSS like this:
.svg {
width: 60%;
}
.icon_phone {
padding-left: 80px;
}
And the SVG would look like this:
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
height="100%" width="100%" viewBox="0 0 97 94.5" enable-background="new 0 0 97 94.5" xml:space="preserve">
<circle fill="#5B2B6E" cx="48.63" cy="47.125" r="42.75"/>
<g>
<line fill="none" stroke="#FFFFFF" stroke-width="5" stroke-miterlimit="10" x1="48.85" y1="47.125" x2="26.41" y2="47.125"/>
<line fill="none" stroke="#FFFFFF" stroke-width="5" stroke-miterlimit="10" x1="70.85" y1="47.125" x2="58.25" y2="47.125"/>
<polyline fill="none" stroke="#FFFFFF" stroke-width="5" stroke-miterlimit="10" points="44.794,65.51 26.41,47.125 44.794,28.74
"/>
</g>
</svg>
I don't know if this would be a good way about doing things, because they behave weird in IE and some browsers, unless I specifically set both width AND height on their parent. Some of the SVGs stretch, some have their heights are all messed up. But in Chrome, everything's good.
What would be the best take on this?
It's better to remove height and width (and x, y and viewBox if needed) attributes from svg itself and use both width and height in css.
Ex:
.parent svg {
width: 100%;
heigth: 100%;
}
.parent {
width: 100px;
height: 50px;
}
Or:
.parent svg {
width: 100px;
heigth: 50px;
}
So you can easily make everything responsive.

i'm trying to build a stroked line, based on a svg file, cause of the color and the corner shapes that it has. Each stroke is 15px wide and has a gap between each line from also 15px. The problem is that when i try to include it via background-image it always makes the line longer than it actually should be.
.stroke-dotted {
background-image: url(data:image/svg+xml;base64,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);
width: 100%;
background-repeat: repeat-x;
}
<div class="stroke-dotted"></div>
Thats how it should look like:
And that's how it looks now:
Is there a way to give the lines a specific width of 15px and also an gap of 15px? I also tried to fix it with the background-size attribute, but it didn't worked out.
First things first: don't encode your SVG as a base64, it is much longer than the original code and its unnecessary as you can just add the code to the url. You might need to URL encode it for IE11 and earlier, but otherwise all browsers support it.
Now, to control your sizing in SVG tags, ommit the viewBox and simply give it a width and height of 100% and express all other values in percentage. Now you can control the size of the line by defining its pixel size, even though the points are defined in percentage:
div {
position: absolute;
width: 100%;
height: 100%;
left: 0%;
top: 0%;
background: url('data:image/svg+xml;charset=utf8,<svg width="100%" height="100%" xmlns="http://www.w3.org/2000/svg">\
<line x1="0%" y1="50%" x2="100%" y2="50%" stroke="cyan" stroke-width="1px" stroke-dasharray="15px 15px" />\
</svg>') no-repeat 50% 50% / cover;
}
body {
/* A reference grid */
background: url('data:image/svg+xml;charset=utf8,<svg width="15px" height="15px" xmlns="http://www.w3.org/2000/svg">\
<rect x="0" y="0" width="100%" height="100%" stroke="#222" stroke-width="1px" fill="black" />\
</svg>');
}
<div></div>
Once your SVG is correctly set up, it is as simple as defining the stroke-dasharray property with the pixel values:
<line x1="0%" y1="50%" x2="100%" y2="50%" stroke="black" stroke-width="1px" stroke-dasharray="15px 15px" />
Now you can use CSS to change your box, or even SVG to change the offsets within the SVG background.
Is it possible to emulate the following CSS in an SVG fill?
background-image: url(/* URL */);
background-position: 50%;
background-size: auto 100%;
background-repeat: repeat-x;
i.e. A background image that has its aspect ratio preserved, has the same height as its container, is centred, and repeats horizontally. This JSBin demonstrates the behaviour I'm trying to implement, using an animation to show how the background responds to height changes.
It's awkward, to say the least, and it is far from perfect. As the outermost element, I have set a html <div> element, but it could also be a <svg> element. The key point is to remember that you need an inner <svg> with overflow: visible, and an outer element with overflow: hidden (which would be the default for an <svg> element.
#keyframes shrink {
0% { height: 200px; }
100% { height: 50px; }
}
div {
animation: 2s ease-in-out 0s infinite alternate shrink;
border: 1px solid #000;
height: 200px;
width: 200px;
overflow: hidden;
}
<div>
<svg width="100%" height="100%" viewBox="-0.675 0 0.1 1"
preserveAspectRatio="xMidYMid meet" overflow="visible">
<pattern id="p1" viewBox="0 0 100 80" height="1" width="1.25"
patternUnits="userSpaceOnUse">
<image xlink:href="http://static.jsbin.com/images/dave.min.svg"
width="100" height="80" />
<rect width="100" height="80" fill="none" stroke="brown" />
</pattern>
<rect fill="url(#p1)" x="-500" y="0" width="1000" height="1" />
</svg>
</div>
The repetitions are not conceptually endless, but merely very long - I've set 1000 / 1.
If the container is higher than wide in respect to the aspect ratio of the svg viewBox, the image will only scale so far that the viewBox still fits inside. This is due to the meet keyword being always applied for both directions. Therefore, the viewBox width needs to be small - I've set 1 / 10.
The size of the image needs to be known in advance, and it must be used in four places:
The <image> width and height must be explicitely set, SVG has no notion of "natural size".
The <pattern> viewBox attribute must be set to the image size. I've added a rectangle to illustrate the image borders.
While the pattern height attribute always needs to be 1, the width has to be set to the correct apect ratio.
If the viewBox on the on the inner <svg> has a value of "x 0 ws 1", and wp is the pattern width, then x = -(wp/2 + ws) - for my example, ws=0.1, wp=1.25 => x=-0.675.
I have a svg tag with two circle elements inside that which are the same as each other. with same X and Y and R. but when I put one of them inside a clipPath and link it to an image or div, the position of the clipped circle will change. what is the problem about it?
It would be appreciated if anyone can help.
Here is the html code:
<div class="clip-background"></div>
<svg width="500" height="500">
<clipPath id="clipping-area">
<circle cx="200" cy="200" r="100">
</clipPath>
<circle class="circle-border" cx="200" cy="200" r="100">
</svg>
And here is the css code:
.clip-background{
position:absolute;
width:500px;
height:500px;
background-color:pink;
clip-path: url(#clipping-area);
-webkit-clip-path: url(#clipping-area);
}
.circle-border{
fill:none;
stroke:#666;
stroke-width:2;
}
codepen here.
This is happening because in your clipPath, the coordinates of the circle are being treated as being relative to the top left of the page. Whereas the circle coordinates in the SVG are relative to the top left of the <svg>. But the SVG is affected by the default margins/paddings on the HTML <body>. And so is not positioned in the same place.
If you get rid of the body margins in the standard way:
BODY {
padding: 0;
margin: 0;
}
you will see they both line up.

I have a svg image that doesn't fit into my div. When I re-size my svg the div doesn't re-size to fit the svg. The svg should be at max size 700px and then re-size down as browser window re-sizes. I had it working with another element in Div1 that stretched the div1 to max-width:700px, but as I deleted that element it stopped working.
I removed the fiddle, since the issue is resolved.
If you have an svg image it will grow as large as its container allows.
This is both in width and height.
So if the svg element looks like this: <svg height="100%" width="100%">
It will scale up until to its container size.
I use css to modify how to control its size:
.svg-class { //put this class on your svg element
width: 100%;
}
So as long as there is room in the parent containers it will grow. Now we want to limit it to 700px: Just add max-width: 700px to the size control:
.svg-class {
width: 100%;
max-width: 700px;
}
Now it will only grow until 700px width. Even if the container is bigger.
body {
margin: 0;
}
.top {
background-color: black;
}
.sprite {
max-width: 700px;
width: 100%;
}
<div class="top">
<svg class="sprite" viewBox="0 0 100 100">
<rect x="0" y="0" width="50" height="50" fill="red" />
<rect x="50" y="0" width="50" height="50" fill="yellow" />
<rect x="0" y="50" width="50" height="50" fill="green" />
<rect x="50" y="50" width="50" height="50" fill="blue" />
</svg>
</div>
I found the answer. I added image tags around the svg and set the width. Works now.
I have a SVG-element with a lot of elements inside. The SVG-element has a viewbox, so you can press a zoom-button and the elements appear bigger or smaller. Works well. Now the problem is, when the elements overflow the parent SVG-element no ScrollBars appear.
Example:
<div width="100%" height="100%">
<svg height="100%" width="100%" style="overflow-x: auto; overflow-y: auto; "viewBox="0 0 793 1122">
<g>
...
<line y2="44.9792mm" y1="44.9792mm" x1="197.203mm" x2="12.7028mm"></line>
<line y2="44.9792mm" y1="44.9792mm" x1="197.203mm" x2="12.7028mm"></line>
<text x="43.4516mm" y="52.9167mm" style="font-size: 11pt;">S</text>
<rect x="0" width="210mm" y="0" height="297mm"></rect>
...
</g>
</svg>
</div>
//here I set the viewbox after clicking the zoomOut-Button
float width = svg.getViewBox().getBaseVal().getWidth();
float height = svg.getViewBox().getBaseVal().getHeight();
svg.getViewBox().getBaseVal().setHeight((float) (height / 0.9));
svg.getViewBox().getBaseVal().setWidth((float) (width / 0.9));
Can someone help me?
I put the overflow attribut in the svg and also in the div tag. doesn't work.
Try making the SVG element bigger than the div, and let the div handle the overflow using scroll.
For example, see this jsfiddle, which utilizes the following css:
div#container {
height: 400px;
width: 400px;
border:2px solid #000;
overflow: scroll;
}
svg#sky {
height: 100px;
width: 1100px;
border:1px dotted #ccc;
background-color: #ccc;
}
Part of the point of SVG is so that it can scale to fit the screen. However, I think if you want to get something like what you are describing, then you need to set explicit width and height to the svg element. Something like http://jsfiddle.net/qTFxJ/13/ where I set the width and height in pixels to match your viewBox size.
