Line Break g elements inside SVG - html

This might be fairly simple question but unable to find the answer. I want to line break g element tags inside svg element.
CSS
.container { position: reletive; width: 200px; background: #ccc; }
.container g { display: inline-block; display: inline; }
HTML
<div class="container">
<svg>
<g transform="translate(0, 0)">
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Canada</text>
</g>
<g transform="translate(100, 0)">
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Germany</text>
</g>
<g transform="translate(200, 0)">
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Norway</text>
</g>
<g transform="translate(300, 0)">
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Russia</text>
</g>
<g transform="translate(400, 0)">
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">USA</text>
</g>
</svg>
</div>
Here is the JSFiddle Link

SVG doesn't have a layout model like HTML, each element is painted on top of the previous elements and doesn't affect positioning of other elements.
You could use separate <svg /> elements so the HTML layout model can take control of positioning / wrapping the elements:
.container { width: 200px; background: #ccc; }
.container svg { width:100px; margin:0; display: inline-block; }
<div class="container">
<svg>
<g>
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Canada</text>
</g>
</svg><svg>
<g>
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Germany</text>
</g>
</svg><svg>
<g>
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Norway</text>
</g>
</svg><svg>
<g>
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">Russia</text>
</g>
</svg><svg>
<g>
<rect width="18" height="18"></rect>
<text x="24" y="9" dy=".35em">USA</text>
</g>
</svg>
</div>

SVG text not horizontally center aligning

I generated a SVG using Adobe XD. They use transform for positioning things but the text in my mini computer screen is not always the same width (it is dynamically generated). I have tried anchored, anything I could find but it still didn't work. This is how it looks with the current code:
Here is the code:
<svg xmlns="http://www.w3.org/2000/svg" width="903.5" height="860.5" viewBox="0 0 1200 1041">
<g transform="translate(-397)">
<g
transform="translate(507 975)"
fill="#fff"
stroke="#707070"
strokeWidth="1"
>
<rect width="907" height="66" rx="33" stroke="none" />
<rect x="0.5" y="0.5" width="906" height="65" rx="32.5" fill="none" />
</g>
<rect width="119" height="395" transform="translate(901 613)" fill="#fff" />
<g
transform="translate(397)"
fill="#232323"
stroke="#fff"
stroke-width="30"
>
<rect width="1127" height="627" rx="103" stroke="none" />
<rect x="15" y="15" width="1097" height="597" rx="88" fill="none" />
</g>
<text
fill="white"
fontSize="96"
fontFamily="Fredoka"
>
{screenText}
</text>
</g>
</svg>
You can use transform/translate, text-anchor and dominant-baseline to place a text in the middle of something.
body {
background: gray;
}
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 1200 1041">
<g
transform="translate(600 975)"
fill="#fff"
stroke="#707070"
stroke-width="1">
<rect x="-453.5" width="907" height="66" rx="33" stroke="none" />
<rect x="-454" y="0.5" width="906" height="65" rx="32.5" fill="none" />
</g>
<rect width="119" height="395" transform="translate(545.5 613)" fill="#fff" />
<g transform="translate(50)"
fill="#232323"
stroke="#fff"
stroke-width="30">
<rect width="1127" height="627" rx="103" stroke="none" />
<rect x="15" y="15" width="1097" height="597" rx="88" fill="none" />
</g>
<text
fill="#fff"
font-size="96"
font-family="Fredoka"
transform="translate(600 300)"
text-anchor="middle"
dominant-baseline="middle">
{screenText}
</text>
</svg>
Thanks to Buhan Yu's comment I learned that you need to specify x and y to center align it. I set x="50%" and it worked!

CSS Select #shadow-root

I'd like to use CSS to set the fill of the bottom right circle to green.
The snippet below successfully colors entire shape to green, but I just want to color part of the shape (just the circle).
[row="2"] [col="b"] {fill: green;}
<svg>
<defs>
<symbol id="myShape">
<polygon points="0,0 40,0 20,20" />
<circle r="10" cx="10" cy="10" stroke="black" />
</symbol>
</defs>
<g row="1" translate="transform(0,0)">
<use col="a" xlink:href="#myShape" x="0" />
<use col="b" xlink:href="#myShape" x="50" />
</g>
<g row="2" transform="translate(0,50)">
<use col="a" xlink:href="#myShape" x="0" />
<use col="b" xlink:href="#myShape" x="50" />
</g>
</svg>
If you want something to always be a specific colour, then set it to be that colour explicitly.
[row="2"] [col="b"] {fill: green;}
[row="1"] [col="b"] {fill: blue;}
<svg>
<defs>
<symbol id="myShape">
<polygon points="0,0 40,0 20,20" fill="black" />
<circle r="10" cx="10" cy="10" stroke="black" />
</symbol>
</defs>
<g row="1" translate="transform(0,0)">
<use col="a" xlink:href="#myShape" x="0" />
<use col="b" xlink:href="#myShape" x="50" />
</g>
<g row="2" transform="translate(0,50)">
<use col="a" xlink:href="#myShape" x="0" />
<use col="b" xlink:href="#myShape" x="50" />
</g>
</svg>

SVG rect as background to text [duplicate]

I want to color the background of svg text similar to background-color in css
I was only able to find documentation on fill, which colors the text itself
Is it even possible?
You could use a filter to generate the background.
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" result="bg" />
<feMerge>
<feMergeNode in="bg"/>
<feMergeNode in="SourceGraphic"/>
</feMerge>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">solid background</text>
</svg>
No this is not possible, SVG elements do not have background-... presentation attributes.
To simulate this effect you could draw a rectangle behind the text attribute with fill="green" or something similar (filters). Using JavaScript you could do the following:
var ctx = document.getElementById("the-svg"),
textElm = ctx.getElementById("the-text"),
SVGRect = textElm.getBBox();
var rect = document.createElementNS("http://www.w3.org/2000/svg", "rect");
rect.setAttribute("x", SVGRect.x);
rect.setAttribute("y", SVGRect.y);
rect.setAttribute("width", SVGRect.width);
rect.setAttribute("height", SVGRect.height);
rect.setAttribute("fill", "yellow");
ctx.insertBefore(rect, textElm);
The solution I have used is:
<svg>
<line x1="100" y1="100" x2="500" y2="100" style="stroke:black; stroke-width: 2"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.6em">Hello World!</text>
<text x="150" y="105" style="fill:black">Hello World!</text>
</svg>
A duplicate text item is being placed, with stroke and stroke-width attributes. The stroke should match the background colour, and the stroke-width should be just big enough to create a "splodge" on which to write the actual text.
A bit of a hack and there are potential issues, but works for me!
Instead of using a <text> tag, the <foreignObject> tag can be used, which allows for XHTML content with CSS.
No, you can not add background color to SVG elements. You can do it programmatically with d3.
var text = d3.select("text");
var bbox = text.node().getBBox();
var padding = 2;
var rect = self.svg.insert("rect", "text")
.attr("x", bbox.x - padding)
.attr("y", bbox.y - padding)
.attr("width", bbox.width + (padding*2))
.attr("height", bbox.height + (padding*2))
.style("fill", "red");
Answer by Robert Longson (#RobertLongson) with modifications:
<svg width="100%" height="100%">
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow"/>
<feComposite in="SourceGraphic" operator="xor"/>
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50"> solid background </text>
<text x="20" y="50" font-size="50">solid background</text>
</svg>
and we have no bluring and no heavy "getBBox" :)
Padding is provided by white spaces in text-element with filter.
It's worked for me
Going further with #dbarton_uk answer, to avoid duplicating text you can use paint-order=stroke style:
<svg>
<line x1="100" y1="100" x2="350" y2="100" style="stroke:grey; stroke-width: 100"/>
<text x="150" y="105" style="stroke:white; stroke-width:0.5em; fill:black; paint-order:stroke; stroke-linejoin:round">Hello World!</text>
</svg>
Note the stroke-linejoin:round which is needed to avoid seeing spikes for the W sharp angle.
You can combine filter with the text.
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>SVG colored patterns via mask</title>
</head>
<body>
<svg viewBox="0 0 300 300" xmlns="http://www.w3.org/2000/svg">
<defs>
<filter x="0" y="0" width="1" height="1" id="bg-text">
<feFlood flood-color="white"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<!-- something has already existed -->
<rect fill="red" x="150" y="20" width="100" height="50" />
<circle cx="50" cy="50" r="50" fill="blue"/>
<!-- Text render here -->
<text filter="url(#bg-text)" fill="black" x="20" y="50" font-size="30">text with color</text>
<text fill="black" x="20" y="50" font-size="30">text with color</text>
</svg>
</body>
</html>
this is my favorite hack (not sure it should work). It refer an element that is not yet displayed, and it works pretty well
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 620 40" preserveAspectRatio="xMidYMid meet">
<defs>
<filter x="-0.02" y="0" width="1.04" height="1.1" id="removebackground">
<feFlood flood-color="#00ffff"/>
</filter>
</defs>
<!--Draw the text-->
<use xlink:href="#mygroup" filter="url(#removebackground)" />
<g id="mygroup">
<text id="text1" x="9" y="20" style="text-anchor:start;font-size:14px;">custom text with background</text>
<line x1="200" y1="18" x2="200" y2="36" stroke="#000" stroke-width="5"/>
<line x1="120" y1="27" x2="203" y2="27" stroke="#000" stroke-width="5"/>
</g>
</svg>
For those wondering how to apply padding to a text element when it has a background like in the Robert's answer, do the following:
<svg>
<defs>
<filter x="-0.1" y="-0.1" width="1.2" height="1.2" id="solid">
<feFlood flood-color="#171717"/>
<feComposite in="SourceGraphic" operator="xor" />
</filter>
</defs>
<text filter="url(#solid)" x="20" y="50" font-size="50">Hello</text>
</svg>
In the example above, filter's x and y positions can be used as transform: translate(-10%, -10%) would, and width and height values can be read as 120% and 120%. So we made background 20% bigger, and offsetted it -10%, so background is now 10% bigger on each side of the text.
The previous answers relied on doubling up text and lacked sufficient whitespace.
By using atop and I was able to get the results I wanted.
This example also includes arrows, a common use case for SVG text labels:
<svg viewBox="-105 -40 210 234">
<title>Size Guide</title>
<defs>
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="white"></feFlood>
<feComposite in="SourceGraphic" operator="atop"></feComposite>
</filter>
<marker id="arrow" viewBox="0 0 10 10" refX="5" refY="5" markerWidth="6" markerHeight="6" orient="auto-start-reverse">

</g>
</g>
</svg>
An obvious workaround to the problem of the blur produced by the filter effect is to render the <text> two times: once for the background (with transparent characters) and once for the characters (without a background filter).
For me, this was the only way to make the text readable in Safari.
<svg width="100%" height="100%">
<filter x="0" y="0" width="1" height="1" id="solid">
<feFlood flood-color="yellow" />
</filter>
<g transform="translate(20, 50)" font-size="50">
<text aria-hidden="true" fill="none" filter="url(#solid)">solid background</text>
<text fill="blue">solid background</text>
</g>
</svg>
The aria-hidden="true" attribute is there to prevent screen readers from speaking the text twice, if the user uses a screen reader.
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example.
Does not work in IE :)

Rotate HTML SVG Text by 270 degrees

I'm struggling to understand how the rotation of text works with the Html SVG Text tags.
I read this, somewhat, similar question rotate x axis text in d3 but the answer doesn't really seem to apply - that i can figure anyway.
Take the following SVG Markup:
<svg>
<g>
<rect x="0" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="2" y="73" font-size="10">1</text>
</g>
<g>
<rect x="20" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="22" y="73" font-size="10">2</text>
</g>
<g>
<rect x="40" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="42" y="73" font-size="10">3</text>
<!-- Trying to rotate this 270 degrees -->
<text x="42" y="73" font-size="10">Missing</text>
</g>
<g>
<rect x="60" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="62" y="73" font-size="10">4</text>
</g>
</svg>
There is some text, in the 3rd group; 'Missing'
I am trying to rotate this 270 degrees, but struggling to understand where it rotates from. I have read it rotates from the origin, but what is the origin in this?
I've tried things like transform="rotate(270, 42, 73)" and various other numbers in place of 42 and 73. I can eventually, with guesswork, get it in the right position though without understanding how it actually works, then i can't add text to the other groups and rotate it.
So, how do i rotate this and, in laymen terms, how does it work?
For clarification - I am looking to achieve:
Text is positioned with the baseline starting at the coordinates you provide. In your example you are positioning the "3" and the "Missing" at the same position. Trying to find the right values for the transform, that will rotate the text into position from there, is unnecessarily complicating the process.
I would suggest positioning the "Missing" where you want the (soon to be vertical) baseline to start and apply the rotation once you find the right position.
First step: position the text
<svg width="200" viewBox="0 0 100 100">
<g>
<rect x="0" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="2" y="73" font-size="10">1</text>
</g>
<g>
<rect x="20" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="22" y="73" font-size="10">2</text>
</g>
<g>
<rect x="40" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="42" y="73" font-size="10">3</text>
<!-- Trying to rotate this 270 degrees -->
<text x="52" y="63" font-size="10">Missing</text>
</g>
<g>
<rect x="60" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="62" y="73" font-size="10">4</text>
</g>
</svg>
Second step: now rotate
(52,63) looks about right. So now we can re-use those coordinates for the rotate().
<svg width="200" viewBox="0 0 100 100">
<g>
<rect x="0" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="2" y="73" font-size="10">1</text>
</g>
<g>
<rect x="20" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="22" y="73" font-size="10">2</text>
</g>
<g>
<rect x="40" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="42" y="73" font-size="10">3</text>
<!-- Trying to rotate this 270 degrees -->
<text x="52" y="63" font-size="10" transform="rotate(270 52 63)">Missing</text>
</g>
<g>
<rect x="60" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="62" y="73" font-size="10">4</text>
<text x="72" y="63" font-size="10" transform="rotate(270 72 63)">Missing</text>
</g>
</svg>
Ultimately, Robert's solution is simpler, but I wanted to help you understand how the rotate transform works with text.
This seems to roughly match the drawing. The rotation origin at the bottom left by default.
<svg>
<g>
<rect x="0" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="2" y="73" font-size="10">1</text>
</g>
<g>
<rect x="20" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="22" y="73" font-size="10">2</text>
</g>
<g>
<rect x="40" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="42" y="73" font-size="10">3</text>
<!-- Trying to rotate this 270 degrees -->
<text transform="rotate(270, 42, 73) translate(10,10)" x="42" y="73" font-size="10">Missing</text>
</g>
<g>
<rect x="60" y="0" width="20" height="75" fill="white" stroke="#CCC" stroke-width="0.5"></rect>
<text x="62" y="73" font-size="10">4</text>
</g>
</svg>

g element rendering outside of svg

I have a bar chart I've created using D3. I've left out the JS code because the issue has to do with html and css not D3.
Run the snippet below. There are 3 sections (g elements) each with a label and 3 bars (with some text inside). The first g element seems to be rendering outside the svg, cutting off the label text, and I cannot figure out why.
Things I've already tried (that don't work):
Position relative on the svg and g elements.
overflow: visible (would be more of a hack than a solution)
wrapping the svg in a clearfix div
I would prefer a solution, opposed to a hack like translate the g elements down by 20 each...
#chart{ width:100%;}
#chart rect {
fill: steelblue;
}
#chart text.value {
fill: white;
font-size: 10px;
text-anchor: end;
}
#chart text.value2 {
fill: white;
font-size: 12px;
}
#chart text.label {
fill: black;
font-size: 20px;
}
<svg id="chart" width="908" height="375">

The text.label elements "baseline" is, by default, at the bottom edge of the text. Meaning, when you render text at (0,0), the text is rendered from the bottom left corner.
To fix your issue, you can add dominant-baseline: hanging; to the text.label rule in your CSS, and adjust the bars down by the height of the text.
