I have a svg mask made of two dots cutting two holes out of a rectangle. This effect works great in webkit browsers, but in firefox I just get a solid rectangle. Firefox is meant to support svg mask - any ideas where I have gone wrong?
body {background:pink}
#overlay {
position: relative;
z-index: 99;
position: absolute;
width: 50vw;
height: 100vh;
}
svg { position:absolute;width: 100%;height:100%}
<div id="overlay">
<svg>
<mask id="mymask" >
<rect class="svg-bg" x="0" y="0" width="100%" height="100%" fill="white"/>
<circle id="hole-1" cx="50%" cy="37vh" r="12vh" fill="#000000"/>
<circle id="hole-2" cx="50%" cy="63vh" r="12vh" fill="#000000"/>
</mask>
<rect id="hole-bg" x="0" y="0" width="100%" height="100%" mask="url(#mymask)"/>
</svg>
</div>

i generated the following svg
<div style="height: 100%; overflow: hidden;" class='parent' ><svg viewBox="0 0 500 150" preserveAspectRatio="none" style="height: 100%; width: 100%;"><path d="M213.19,0.00 C152.69,70.06 270.03,70.06 202.98,150.00 L500.00,150.00 L500.00,0.00 Z" style="stroke: none; fill: #08f;"></path></svg></div>
the problem is that when i try to add background image for example here on the parent class
.parent {
background-image: url('../../../assets/images/calendar.png');
}
then the image is hidden behind the blue color of the svg.How can i 'insert' this image to be on the blue svg color image ?
As name says - it's "background-image" so it always is on the background of selected element.
I suggest that you should make an <img> tag in parent element and style it so that .parent would have attribute position: relative and img should have position: absolute.
Also remember to set top and left/right position for <img>.
it's Answered here https://stackoverflow.com/a/3798797/9017484
You can do it by making the background into a pattern:
<defs>
<pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
<image href="wall.jpg" x="0" y="0" width="100" height="100" />
</pattern>
</defs>
your code should be something like this:
<div style="height: 100%; overflow: hidden;" class='parent' >
<svg viewBox="0 0 500 150" preserveAspectRatio="none" style="height: 100%; width: 100%;">
<defs>
<pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
<image href="ImageFile.jpg" x="0" y="0" width="100" height="100" />
</pattern>
</defs>
<path d="M213.19,0.00 C152.69,70.06 270.03,70.06 202.98,150.00 L500.00,150.00 L500.00,0.00 Z" style="stroke: none; fill: url(#img1);"></path>
</svg>
</div>
change the opacity level so the color is lower opacity. something like this perhaps.
background {
backgroundColor:blue,
opacity: 0.5;
}
The initial SVG figure with pattern:
<svg width="200" height="200" viewBox="0 0 100 100">
<defs>
<pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%">
<circle cx="2" cy="2" fill="white" r="0.8"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="100" height="100" fill="url(#img-dotted-dots)"></rect>
</mask>
</defs>
<path d="M0 0 H 100 V 100 H 0 Z" mask="url(#img-dotted-mask)" fill="#1063B1"></path>
</svg>
Need to achieve:
One instance of the SVG figure with pattern for refferencing with CSS as clip-path.
I have tried to create SVG clipPath element and bind to CSS clip-path by this way
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<pattern
patternUnits="objectBoundingBox"
patternContentUnits="objectBoundingBox"
x="0" y="0" height="0.1" width="0.1">
<circle cx="0" cy="0" fill="white" r="0.5"></circle>
</pattern>
</clipPath>
</defs>
</svg>
Nothing happens.
Expected result - the same as the previous snippet.
For comparing:
If I use SVG rect - CSS clip-path works.
If pattern - doesn't
.figure {
width: 300px;
height: 300px;
clip-path: url(#img-dotted-clip-path);
background-color: #1063B1;
}
<div class="figure"></div>
<svg width="0" height="0" viewBox="0 0 100 100">
<defs>
<clipPath
clipPathUnits="objectBoundingBox"
id="img-dotted-clip-path">
<rect width="1" height="1"></rect>
</clipPath>
</defs>
</svg>
The only things that are valid inside a clip path are:
Shape elements (‘circle’, ‘ellipse’, ‘line’, ‘path’, ‘polygon’, ‘polyline’, ‘rect’)
‘text’
‘use’
Plus you can use animation elements etc to animate the clip path. However, only the shapes of those elements are used. Effects such as patterns, filters, etc are ignored.
The only way you could get the effect you want to work as a clipping path would be to add numerous <circle> elements to your <clipPath>.
<clipPath>
<circle>
<circle>
<circle>
<circle>
... etc ...
</clipPath>
But you could use a mask instead. Masks allow patterns.
.figure {
width: 300px;
height: 300px;
-webkit-mask: url(#img-dotted-mask);
mask: url(#img-dotted-mask);
background-color: #1063B1;
}
<p>This only works in Firefox</p>
<div class="figure"></div>
<svg width="0" height="0">
<defs>
<pattern id="img-dotted-pattern"
viewBox="0 0 1 1"
patternUnits="userSpaceOnUse" x="0" y="0" width="20" height="20">
<rect width="1" height="1" fill="black"/>
<circle cx="0.5" cy="0.5" fill="white" r="0.15"></circle>
</pattern>
<mask id="img-dotted-mask">
<rect width="2000" height="2000" fill="url(#img-dotted-pattern)"/>
</mask>
</defs>
</svg>
However inline SVG masks applied to HTML elements, like my example above, only work in Firefox. To get an SVG mask to work in Chrome, you would need to use mask or mask-image with an external or Data URL (as Temani has done in their answer).
You can recreate the same thing using mask combined with radial-gradient
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
/*radius here size here*/
-webkit-mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
mask:radial-gradient(3px, #fff 97%,transparent 100%) 0 0/20px 20px;
}
body {
background:#f2f2f2;
}
<div class="figure"></div>
Or consider the SVG inside the mask property. Make sure to escape the # and correctly set the viewbox and width/height to have a perfect repeat
.figure {
width: 300px;
height: 300px;
background:linear-gradient(to right,red,#1063B1);
-webkit-mask:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="200" height="192" viewBox="0 0 100 90"><defs><pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%"><circle cx="2" cy="2" fill="white" r="0.8"></circle></pattern><mask id="img-dotted-mask"><rect width="100" height="100" fill="url(%23img-dotted-dots)"></rect></mask></defs><path d="M0 0 H 100 V 100 H 0 Z" mask="url(%23img-dotted-mask)" fill="%231063B1"></path></svg>');
mask:url('data:image/svg+xml;utf8,<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="200" height="192" viewBox="0 0 100 90"><defs><pattern id="img-dotted-dots" x="0" y="0" height=".08" width="7.69%"><circle cx="2" cy="2" fill="white" r="0.8"></circle></pattern><mask id="img-dotted-mask"><rect width="100" height="100" fill="url(%23img-dotted-dots)"></rect></mask></defs><path d="M0 0 H 100 V 100 H 0 Z" mask="url(%23img-dotted-mask)" fill="%231063B1"></path></svg>');
}
body {
background:#f2f2f2;
}
<div class="figure"></div>
I generated a simple svg image and loaded it to Chrome. Meant to position it to the center of browser(even when the browser resizing), but so far have failed on this.
Have referred to some articles about viewport/viewbox setting, and some Q&As on this site(https://stackoverflow.com/questions/8639383/how-do-i-center-an-svg-in-a-div;https://stackoverflow.com/questions/13373169/align-svg-to-center-of-screen), but haven't got it done. Maybe I missed something, since I am very new to this.
Here is the full code for this svg image:
<svg
xmlns="http://www.w3.org/2000/svg"
xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"
width="100%"
height="100%"
viewBox="0 -700 1080 1920"
preserveAspectRatio="xMidYMid meet"
version="1.1"
id="mysvg"
>
<g
id="group" >
<circle
r="500"
style="fill:#ffb721;fill-opacity:1"
cy="0"
cx="0"
id="path" />
<circle
style="fill:#f71c17;fill-opacity:1;"
id="path2"
cx="0"
cy="0"
r="250" />
</g>
</svg>
I expect this image could stay at the center of the browser, even during browser resizing.
I think this is what you want?
The SVG will be position in the center even the browser resized and scroll
ON GLOBAL CSS
CSS:
#container {
top: 50%;
left: 50%;
position: fixed;
transform: translate(-50%, -50%);
}
INSIDE SVG
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 439.29 439.29" width="100%" height="100%">
<g id="group">
<circle cx="219.64" cy="219.64" r="219.64" style="fill: #ffb721" id="path"/>
<circle cx="219.64" cy="219.64" r="108.32" style="fill: #f71c17" id="path2"/>
</g>
</svg>
Your SVG needs a little modification to center it in the ViewBox.
body {
min-height: 100vh;
display: flex;
align-items: center;
justify-content: center;
}
.container {
width: 300px;
height: 300px;
background-color: rgba(red, .3);
}
<div class="container">
<svg
xmlns="http://www.w3.org/2000/svg"
xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"
width="100%"
height="100%"
viewBox="-540 -960 1080 1920"
preserveAspectRatio="xMidYMid meet"
version="1.1"
id="mysvg"
>
<g
id="group" >
<circle
r="500"
style="fill:#ffb721;fill-opacity:1"
cy="0"
cx="0"
id="path" />
<circle
style="fill:#f71c17;fill-opacity:1;"
id="path2"
cx="0"
cy="0"
r="250" />
</g>
</svg>
</div>
I'm a newbie in SVG so it's probably an easy question. I'm trying to make an SVG Mask with a simple triangle shape inside a rectangle. What I want to achieve is to get the rectangle responsive with his width but the triangle should
- get a fixed size
- be always at the center of the viewport
You'll understand better with my snippet:
.header-arrow {
height: 70px;
}
svg {
height: inherit;
}
#arrow-down-alpha {
transform: translateX(calc(50vw - 130px/2));
}
<div class="header-arrow">
<svg width="100%">
<defs>
<mask id="myMask" x="0" y="0" width="100%" height="100%">
<rect fill="white" x="0" y="0" width="100%" height="100%" />
<polygon id="arrow-down-alpha" fill="black" x="00" y="0" width="165px" height="100%" points="55.91 37.8 111.81 0 0 0 55.91 37.8" />
</mask>
</defs>
<rect id="base-mask" mask="url(#myMask)" x="0" y="0" width="100%" height="100%" />
</svg>
</div>
It's workning right now in chrome, but the translateX (or translate) is not working in firefox and edge. I've tried to use the transform SVG attribute but it seems that I can't use percentages values.
I'm not realy familiar with the viewbox but I'm not sure it will help in this case.
Thanks anyway for any kind of help !
Here's one way to achieve what you want without relying on new units or calc(). It should be cross-browser compatible also.
How it works:
We wrap the triangle in a nested SVG. We use an SVG because it has an x attribute which can take percentages.
We position this nested SVG at x="50%". It is now centred in the mask (roughly, see next step).
We move the triangle shape so it is centred at x=0. That's so that it is not offset from the centre of the mask.
We set overflow="visible" on the nested SVG so the part of the triangle that is now off the left of the SVG (ie. x < 0) are not clipped.
.header-arrow {
height: 70px;
}
svg {
height: inherit;
}
<div class="header-arrow">
<svg width="100%">
<defs>
<mask id="myMask" x="0" y="0" width="100%" height="100%">
<rect fill="white" x="0" y="0" width="100%" height="100%" />
<svg x="50%" overflow="visible">
<polygon fill="black" points="0 38 56 0 -56 0" />
</svg>
</mask>
</defs>
<rect id="base-mask" mask="url(#myMask)" x="0" y="0" width="100%" height="100%" />
</svg>
</div>
I have 2 SVG rectangles connected by one canvas. I tried HTML5 to make it responsive. SVG is reacting to the code, but the canvas is static, so the connection between them is lost. What can i do?
Try to use an svg element as a ViewBox.
e.g.:
<svg viewBox="0 0 1 1">
<rect width="0.4" height="0.3" y="0" x="0" fill="yellow"/>
<rect width="0.2" height="0.2" y="0" x="0" fill="blue"/>
</svg>
<svg style="position:relative; top: 20x; left: -4px;width: 200; height: 175">
<rect x="5" y="2" rx="20" ry="20" width="100" height="150" style="fill:#FF7070;stroke:black;stroke-width:5;opacity:0.5">
</rect>
</svg>
<svg style="position:absolute; top: 80px; left: 430px">
<rect x="5" y="2" rx="20" ry="20" width="200" height="100" style="fill:#FF7070;stroke:black;stroke-width:5;opacity:0.5">
</rect>
</svg>
<canvas id="canvas1" style=" background-color : gray; position: absolute;top:112px;
left: 110px ;x-index:1;" width="323" height="7" `enter code here`>
</canvas>
