I've got this inline SVG on my site
JSFiddle
Problem seems to be somewhere around this line.
<line
x1="25%" y1="-567"
x2="25%" y2="200%"
style="stroke-dasharray:6 11;"
transform="skewY(45)" />
On different versions of Firefox I see some glitches with missing or flicking parts of image. In chrome/edge everything is OK. Am I using some non-standard SVG stuff, or it's just some FF bug? And is there any workarounds?

I am using contenteditable="true" to edit text in SVG. In all browsers except Safari it works.
Safari has an issue with caret position:
Sample code:
[contenteditable]{
-webkit-user-select:text;
user-select:text;
}
<div contenteditable="true" style="background: #ffe7e7">
<svg style="display:inline-block">
<text id="text" y="2em">Hello world</text>
</svg>
</div>
I have had a similar issue in the past. Unfortunately, the answer was to admit that safari sometimes has particular issues and I had to decide between supporting safari for that or rethinking the approach. Since I didn't want to drop saffari, I totally rethought the need for that layout, but YMMV. You can find the issue tracker for safari issues related to contenteditable here.
We have solved the issue by implementing our own caret. System caret is hidden by style rule.
If your Safari browser is up to date (contenteditable is fully supported from 3.1.), most likely your problem is that webkit and safari are very buggy with contenteditable. Here are Safari's bugs.
I have the following structure on my website, which should display an image within an svg tag.
<div class="wrapper">
<svg width="100%" height="100%">
<g class="image-map-container" transform="translate(143, 221.5) scale(1)"><image xlink:href="https://source.unsplash.com/random"></image></g>
</svg>
</div>
As you can probably imagine, I use this structure in combination with JS to scale and move the image within a set container.
This approach works great in Chrome, newer versions of Firefox and Safari 13.1, but in Safari 12.1 and in Firefox version 68 and downwards, the image isn't displayed at all.
What could be the reason for this?
I created the following snippet for reproduction purposes:
https://codepen.io/pasa/pen/RwaRrKm
I have been developing a web page "game" on my PC based in HTML, SVG, and Javascript. It has a large image of the earth loaded into the SVG views through the SVG <image> tag. Testing on my PC this works with no problem, however recently I published it to a public web page (http://rbarryyoung.com/EarthOrbitalSimulator.html) and discovered that only the bottom right quarter of the SVG is rendering on both SVG views on my iPhone and iPad. Like this:
At first, I thought that it was just the image in the SVG viewports, but then I realized that the entire SVG viewport was black except for the lower-right quadrant. The SVG viewport is correctly fully sized, it just appears as if there is some black mask over 3/4s of it (or only 1/4 of it renders).
Here's what I think are the relevant HTML code lines, the containing Div tag for the first SVG view (line 67):
<div id="divSvg1"
style="position:relative; z-index:1; margin:15px;
top:100px;
width:640px; height:640px;
background-color:black;
float:left;"
>
The SVG tag (line 104):
<svg id="svgEa"
style="width:100%; height:100%;"
viewBox="-7500 -7500 15000 15000"
preserveAspectRatio="xMidYMid meet"
clip-path="url(#svgEaClip)"
transform="scale(1.0,1.0)"
version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<!-- NOTE: All internal units are in KM (or %) -->
And the embedded Image tag (starting at line 160):
<g id="gEaAll" transform="scale(1.0,1.0)" >
<!-- ... -->
<g id="gEaSurfaceFacingBottom" class="eaSurfaceFacing">
<g id=gEarthImage>
<!-- ... -->
<image x="-6413" y="-6413" width="12826" height="12826" href="eosImages/globe-arctic 8bit.png" />
</g>
</g>
The second SVG view is a shadowed (<use..> tag), zoomed view of the first with the same problem.
I have tested this on my PC, on both screens in Chrome, Edge, and IE, where it works correctly on all of them. I have also tested this on my iPhone with both Safari and Edge and my iPad with Safari, Chrome, and Edge with the same failure on all of them. I have tried just a bare <img> tag of the PNG file outside of SVG and that works fine on these platforms.
I do not have any Android platforms to test with, so if anyone wants to try it and let me know, I can add those results here.
I have researched this, and though there's a bunch of stuff about iOS not rendering images, mostly those are a complete failure to render, rather than this very specific partial rendering, and much less specific stuff about SVG differences. Ultimately I didn't find anything that seemed to be the same problem.
To summarize then, my question is: what is causing this problem or what have I done wrong, and how can I fix it? (I do understand that I will need to have a different style/CSS layout for mobile, but I still need to know what needs to be changed to make this render correctly)
Add X and Y coordinates for your <rect />. In your case, your Clip-Path Rectangle is not in an exact coordinate.
Here is the code working for me
<clipPath>
<rect x="-7500px" y="-7500px" width="100%" height="100%" />
<cliPath>
replace this code with your <clipPath> on line 114 and 301.
Here is the Screenshot
Moreover here is a live demo that worked on my Mac Safari as well in windows Chrome, where I took one part of your code.

Orignal answer:
You can try the -webkit- prefix before clip-path. It seems to be a safari issue related to clip-path.
Safari 6.1.5 is not displaying a pattern in an SVG rectangle. I've finally simplified it down to this test case:
<html>
<head>
<style>
.patterned { fill: url("#myid") none; stroke:blue}
</style>
</head>
<body>
<svg width="2880" height="592">
<defs>
<pattern id="myid" patternunits="userSpaceOnUse" x="0" y="0" width="20" height="20">
<circle r="10" cx=12 cy=10 fill="purple">
</pattern>
</defs>
<rect class="patterned" height="27" width="58">
</svg>
</body>
</html>
Safari displays an empty blue outline, while Firefox and Chrome show polka-dots inside it. I have the same problem with the diagonal hatch pattern I'm using in the real thing.
I actually stumbled on a strange workaround that works for this snippet but not for the real thing: changing none to yellow after the url shows purple circles on a white/transparent background on all three browsers. Unfortunately, when I do that in my real application I get a yellow background and no pattern.
I now think my test case is a red herring; it fails for a different reason than my real web site fails to show the pattern. Safari can be made to produce the same result as the other browsers just by deleting the none after the URL. (Possibly a bug in Safari; see other answer.)
Unfortunately, that just means I failed to reduce my real problem to a small test case, because the real thing still doesn't work. After more experimentation, I found that I can break the corrected test case by adding a <base> element to the header. Presumably Safari doesn't resolve the url("#myid") correctly. (Also, Firefox and Chrome seem to resolve it differently if it appears in a file called styles/style.css; Chrome apparently uses the main document as the base, Firefox apparently looks for the {{defs}} in the style sheet.)
And yet Safari does still work if I serve the same the corrected test case as http://localhost:3000, so it's not as simple as file: vs. http:. It must be something else, somewhere in the huge complex web app I've taken over developing. I've now tried three times to isolate the problem by deleting elements until the pattern works (which is how I discovered that Firefox doesn't like the style being defined from another folder), but I've had no luck in isolating the problem with Safari.
I've given up for now and taken a different approach to get the visual effect the designer wants.
I don't have any problems using clip-path with links to .svg files in Firefox, but Safari seemingly refuses to use them.
If you load my WIP page http://www.omakadesign.com in Firefox, you will see a butterfly pattern at the bottom of the menu, but if you load it in Safari, the menus are completely rectangular.
The relevant line appears in main.css (221) and looks like:
clip-path: url("../img/menu-news.svg#news-clip");
There seems to be very little information about clip-path and Safari, and not many questions about it on this site either (believe me I've looked). But then again, I can't even get the most basic inline svg example with clip-path to work even in Firefox, so perhaps there is something fundamental I'm missing on this topic?
(Also, though this is another subject, why these menus have both padding and margin on the bottom is a mystery to me since I zero them out using min-width...)
UPDATE:
I did a test and created a .svg with a mask tag in it and replaced the clip-path line that appears above with a css mask instead (still 221 if you want to try it with the Firefox Style Editor) and amazingly that still works in Firefox and Safari STILL skips over it:
mask: url("../img/menu-news-mask.svg#news-mask");
(Final update: Found the solution, but I'm not allowed to post it for another 5 hours... turns out, you have to use very, very specific SVG and use -webkit-mask for Safari.)
I found the solution. You have to use VERY SPECIFIC SVG code! Follow the example of this guy to the letter, and clipping will work in Safari too:
https://github.com/Modernizr/Modernizr/issues/213#issuecomment-1149691
(Sorry about posting my own answer for my own first question, but I was really desperate and I usually find that when you start asking others, that's when you stumble upon the solution...)
EDIT: Doesn't work in IE9, which I don't really care about, but just a heads up for those who do (the fallback is simply a plain rectangular menu for me which still works).
Thank you for having that link to Modernizr's github!
For a note on if you are clipping an image, what's important is the path has to be inside the clipPath.
On a side note, if you export your SVG Code from Illustrator. Just make sure to use the actual path instead of this:
<defs>
<path id="path" d="....">
</defs>
<clipPath id="clipping">
<use xlink:href="#path"/>
</clipPath>
<image clip-path=url(#clipping) ...>
to the actual path like this...
<clipPath id="clipping">
<path id="path" d="....">
</clipPath>
<image clip-path=url(#clipping) ...>
It will work in FF, Chrome, Safari, Opera and IE9 & 10.
Here's the jsfiddle
Edit
The original issue now I realized is a slightly different problem than what I had... Which is using the svg path to clip an image outside of the svg as an img tag. Unfortunately, IE, even 10 didn’t work when I tried the exact same method. Therefore, if you have have a single image, best is to embed the image inside the svg itself instead of clipping an img tag with the path. That worked for IE9&10 and then some..
For second part of your question (..why these menus have both padding and margin on the bottom..) :
main.css line 95
nav a {
background: none repeat scroll 0 0 #616161;
color: white;
display: block;
font: 12px/20px Lucida Sans Unicode,Lucida Grande,Lucida Sans;
margin-bottom: 10px;
padding: 15px 0;
text-align: center;
text-decoration: none;
}
