How to make a full width overlay with masked portions - javascript

I'm trying to make a massive overlay for a site using css masks. It doesn't seem to work however. I have created a div to be the overlay and then made an svg with some cut-outs to be my masked portions. I expect to see the specified shape cut-out, but I can't see anything of the sort.
body{
background: red;
}
.overlay{
width: 100%;
height: 100%;
background-color: white;
position: fixed;
top: 0;
left: 0;
z-index: 1000;
opacity: 0.8;
}
<svg width="0" height="0">
<defs>
<mask id="hole">
<rect width="100" height="100" fill="blue"/>
<rect x="200" y="100" width="100" height="100" fill="yellow"/>
</mask>
</defs>
</svg>
<div class='overlay'
mask="url(#hole)"></div>
Does anyone know what I'm missing here?
PS: I think this is the most straightforward approach for my use-case. I'm trying to insert page markers into third party sites and then create a whole page overlay which fades out the website background, but leaves only my markers fully visible. I considered using clip-path, but it seems that does the reverse of what I need. I want something that shows my image, except for the positions/shapes specified.

how can I Create a popup ballon on an SVG image?

I have an SVG image that is a map and I would like to apple on some parts of the map the hover action that will show a popup balloon with some information about that part and also a button to redirect the client to another page.
I got the map parts with CSS classes that I added and I tried to make a div with the absolute display but it does not look responsive and changes the position based on the screen size.
there are somehow make it responsible on top of SVG image?
You can use <title>content</title> as part of the SVG code, to include text data as hints (the browser will show a standard tooltip).
Also, you can add events to track the pointer position and put some custom tooltip over there.
var elements=document.getElementsByClassName("hint");
var tooltip=document.getElementById("tooltip");
for(var i=0; i<elements.length; i++){
elements[i].addEventListener('mousemove', function(ev){
//console.log('move',ev.offsetX,ev.offsetY);
tooltip.innerHTML=ev.target.firstChild.textContent;
tooltip.style.left=ev.pageX+"px";
tooltip.style.top=(ev.pageY+20)+"px";
tooltip.style.display='block';
})
elements[i].addEventListener('mouseout', function(ev){
//console.log('out',ev.offsetX,ev.offsetY);
tooltip.innerHTML=ev.target.firstChild.textContent;
})
};
circle{
border: 1px solid #ff0;
}
#tooltip{
position: absolute;
background-color: #fff;
padding:4px;
width: 50px;
z-index: 1;
display: none;
}
<div>
<div>Interactive SVG Example</div>
<div id="tooltip"></div>
<svg version="1.1"
baseProfile="full"
width="300" height="200"
xmlns="http://www.w3.org/2000/svg">
<rect width="100%" height="100%" fill="black" ><title>Black</title></rect>
<circle class="hint" cx="150" cy="100" r="30" fill="blue" ><title>blue</title></circle>
<circle class="hint" cx="250" cy="100" r="20" fill="red" ><title>red</title></circle>
</svg>
</div>
So if you put some div in absolute position you can just react on window resize. After pop up just hook function position you balloon and update position on windows resize event, (you can throttle it by lodash/throttle).If you don't want use js, you can try by css calc with width of window or you're svg container. Give us code example then some one can tell you more.

Plot path that overlaps itself marking overlappings

I'm trying to plot the trefoil knot parametrized like in its wiki, using svg.js (but I can change the tool if it's necessary). The problem is that I can't achieve marking the zones where it overlaps like is done here.
I want to think the person that did that example plotted it in a smart way avoiding to deal with each of those spaces one by one, because otherwise doing something like that svg would be a bit expensive (in relation of time) if you need to change of model (or just another knot).
Does anyone know how was it done or was it solved by hand dealing with each space one by one?
The basic idea would be to mask the interruptions. For DRY code, define the rendered path first as templates for reuse.
path {
fill: none;
stroke: black;
}
mask rect {
fill: white;
}
.shadow {
stroke-width: 20;
}
.knot {
stroke-width: 10;
}
<svg style="width:100px;" viewBox="0 0 100 100">
<defs>
<!-- path templates for multiple use -->
<path id="lower" d="M10 10 90 90" />
<path id="higher" d="M10 90 90 10" />
<mask id="mask">
<!-- white background: everything is visible -->
<rect width="100%" height="100%" />
<!-- black line: masked out space for higher path -->
<use href="#higher" class="shadow" />
</mask>
</defs>
<!-- lower path with masked-out gap -->
<use href="#lower" mask="url(#mask)" class="knot" />
<!-- higher path uninterrupted -->
<use href="#higher" class="knot" />
</svg>

Centering icon inside SVG circle chart

I'm trying to put an icon inside an SVG circular graph so that it will display like this: SVG graph example.
No matter what I do, there's always a slight gap between one side of the inner icon and the SVG path that displays like this. I think the issue has to do w/the fact that the arc degree for the SVG circular graph isn't a perfect circle
Here's everything I've already tried:
Created a static png of the inner icon image so that it wasn't a perfect circle + then wrapped the SVG around it
Created SVG in illustrator with the inner icon as a png with two outer paths: one for the grey fill all around and one for the green fill to represent 50%. When I export the file, the d parameter is displaying based on coordinates, not percentages.
<path d="M82,153.53C122.23,153.41,153.2,121,153.46,82,153.69,43.3,122.59,10.94,82,10.49"
fill="none" stroke="#7aef93"
stroke-miterlimit="10" stroke-width="15" />
I started playing around w/this on CodePen, but didn't get very far.
Is this even possible to achieve? I'd really appreciate any and all help/feedback!
This is a fast solution, I don't know is it good. You should add class circle to the second svg like this:
<svg class="circle" width="120" height="120" viewBox="0 0 120 120" fill="none" xmlns="http://www.w3.org/2000/svg"

And then you should add this css:
.circle {
position: absolute;
top: 25px;
left: calc(50% - 108px);
}
This should make a second svg inside first svg.

Cutting out a text shape from background that can be resized dynamically

I'm trying to create a box that is opaque, but has a block of text in it that you can see through (to like the background image of the page or some element underneath).
It's hard to explain so I've made some crude diagrams:
I am attempting to use SVG files to do this and use Javascript/jquery to modify the rectangle width and height but I'm not proficient at the SVG format... I've managed to piece this together using the evenodd filter:

I don't know how to modify the size/position of the text and rectangle independently well. I can barely understand what I wrote and why the margin is so big.
If anyone could help me, through this or any other method, thank you!
Edit: someone pointed out that there may be a duplicate, but that solution does not work in Firefox unfortunately. I am looking for a cross “platform” solution. But thanks for the link, it’s very helpful nonetheless.
My suggestion is to create a mask using the text. We then create a blue rectangle that we mask with the our text mask.
We can postion the SVG and have it size the way we want using SVG width and height. But we also make the blue rectangle very large and have the SVG set to overflow: visible. This allows us to easily have the SVG size be responsive and also have the blue extend to all the way to the edges of the screen.

SVG get current animation progress (SMIL) in <path>: stroke-dashoffset

I am having very simple animation of path element. Animation applies to stroke-dashoffset attribute. Problem that I am facing is that I can't get animation progress after pause animation.
Here is my SVG code and javascript which actually do nothing but pause and start animation:
setTimeout(function(){
$('.svg')[0].pauseAnimations();
// get current stroke-dashoffset value ??
// $('#stroke')[0]['stroke-dashoffset'].animVal - it doesn't work
$('.svg')[0].unpauseAnimations();
}, 500); // 500 is testing value (!) it can be anything
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<svg xmlns="http://www.w3.org/2000/svg" width="100" height="100" class="svg">
<path d="M47.488,10.079A40,40,0,0,0,16.302,71.551" id="stroke" style="stroke-width: 10px; fill: none; stroke: #333;" stroke-dasharray="83.07828521728516px 83.07828521728516px" stroke-dashoffset="-83.07828521728516px">
<animate attributeName="stroke-dashoffset" id="anim2" dur="1000ms" from="-83.07828521728516px" to="-39.095663631663605" fill="freeze"></animate>
</path>
</svg>
I know how to get animation progress when using <circle> element: https://stackoverflow.com/a/17217470/1736186 but I don't know how to get stroke-dashoffset value in <path>.
I can get it done by combining timeout with min/max stroke-dashoffset and calculate approximate progress, but I believe (hope) I am missing something and it can be done easily with animVal.
So please don't post an answer with that kind of solution, because I know how to do it by myself.
Quite interesting, I didn't know there weren't an animVal for all animatable attributes, but it seems that stroke-dashoffset attribute, is directly converted to its style equivalent.
So for your problem, a simple solution is to request the computed style of your element :
setTimeout(function(){
$('.svg')[0].pauseAnimations();
// get current stroke-dashoffset value
console.log( getComputedStyle($('#stroke')[0]).strokeDashoffset );
$('.svg')[0].unpauseAnimations();
}, 500); // 500 is testing value (!) it can be anything
