offset-path leaving a fading trail - javascript

what do I need to include to make a white trail following it? I tried adding 10 spans and giving them the same path and delaying each one but it looked so off.

Here's an implementation that uses SVG <animateMotion> instead of CSS offset-path. (The path data might look a bit different, but they are basically the same.)
The trail is done with a stroke-dashoffset animation. The path gets the pathLength="100", and is then drawn ten times, each with a stroke-dasharray="2 98". That way, only a dash with a length of 2 of 100 along the path is drawn.
Then, each of the ten copies of the path gets a fading opacity, and its stroke-dashoffset is animated such that they are positioned one behind the other and moving behind the glowing orb. That part gets admitedly a bit verbose, as you need to write an individual animation rule for each of the copies. The combination of them all is then blured to smooth it.
For the orb, a custom SVG filter is used, since the drop-shadow property can't be used directly for SVG grafics.

You could write the trail animation also with <animate>. It would look like this:
<use href="#ellipse">
<animate attributeName="stroke-dashoffset"
dur="10s" repeatCount="indefinite"
from="2" to="-98" />
</use>
Which variant you use is a matter of taste.
Edit: Generalization
The above code depends on a linear movement of the orb along the path. How would you solve this with different easings? I started to explore that and found the only realistic approach is to draw the trail frame-by-frame from Javascript. An example can be found in this Codepen.

How to stop SVG animation on click?

js
var vawe = document.getElementById("vawe")
vawe.addEventListener('click',function() {
vawe.classList.toggle('stop');
})
when I click on the svg I want to stop pause the animation, so that the music stop, and then click again the animation starts again.

#wave.stop {
animation-play-state: paused;
}
Doesn't apply the animation-play-state to the actually animated (line) elements.
The css rule should rather look something like this:
#wave.stop .t {
animation-play-state: paused;
}
I also recommend to use class selectors to avoid unnecessarily high specificity
(introduced by id selectors in your css rules).
var wave = document.getElementById("wave")
wave.addEventListener('click', function(e) {
e.currentTarget.classList.toggle('stop');
})
.loader {
display: flex;
align-items: center;
justify-content: center;

}
#wave {
height: 10em;
fill: black;
}
.stop {

}
.stop .t {
animation-play-state: paused;
}

Since the delay is required on resume, try this JavaScript alternative. The animation property of the element is individually set or unset depending upon the state.
let el = document.getElementById("vawe")
el.addEventListener('click', (e) => {
let value = 'unset';
if ( e.currentTarget.classList.contains('stop') ) {
e.currentTarget.classList.remove('stop');
value = 'pulse 1s infinite';
} else {
e.currentTarget.classList.add('stop');
}
e.currentTarget.childNodes.forEach(child => {
child.style.setProperty('animation-name', value);
});
});

Make SVG graphics play on entering window (scroll)

I have a tough question! I have several SVG graphics on some of my pages which play when the page loads. But because many of them are below the fold, I would like them to start playing (and play once) when they scroll into view.
NOTE: I have searched everywhere for a solution and even hired a freelancer who couldn't make it work. The difference with my SVGs I think is that they use #keyframe and have more than one path that play in sequence which may be why other solutions do not work? The reason for more than one path is that it is a calligraphic arrow shape that overlaps when revealed by the SVG mask.
My HTML for one of the SVGs (inside a DIV to make it responsive):

I haven't posted any JS because none of the code I have tried works.

You can achieve that by running the animation if the container #arrow-1id as a specific class (lets say .play). Then you just check with javascript when the container appear in the screen. When it's the case, just add the .play class to the container:
var body = document.getElementsByTagName("body")[0];
var div = document.getElementById("arrow-1id");
body.onscroll = function() {
if (document.documentElement.scrollTop >= div.offsetTop - 200) {
div.classList.add("play");
}
};
body {
height: 2000px;
}
#arrow-1id {
margin-top: 400px;
background-color: lightgrey;
}

I tried this and it works but it seems only supported in Firefox, no other browser???
<script type="text/javascript">
var diva2 = document.getElementById("arrow-2id");
window.addEventListener("scroll", function() {
if (document.documentElement.scrollTop >= diva2.offsetTop - -500) {
diva2.classList.add("play");
}
}
);

How to show a tooltip after clicking an SVG?

I have an SVG circle, it has a small svg circle inside it and a polygon inside the small circle, when i click on the polygon it should rotate and it's working fine, but after rotation a tool-tip should appear above the polygon and i don't know how to show it, i put it in a div above my svg, here is my code:
document.querySelector('polygon').addEventListener('click', function() {
this.classList.toggle('rotated');
});
.rotated {
transform: rotate(-90deg);
}
polygon {
transition: all 1s;
}
<div class="marker marker-index-0" style="display: none;">
<h3>I should be a tooltip</h3>
</div>
<svg>
<circle cx="40" cy="122.5" r="26" fill="red"></circle>
<g class="markerG" transform="matrix(1,0,0,1,40,122.5)"><circle cx="0" cy="0" r="14" fill="#000000" style="cursor: pointer;"></circle><polygon points="1 -1 1 -7 -1 -7 -1 -1 -7 -1 -7 1 -1 1 -1 7 1 7 1 1 7 1 7 -1" fill="#ffffff"></polygon></g>
</svg>

Looks to me like you never specified to show the tool-tip ;)
document.querySelector('svg').addEventListener('click', function() {
document.querySelector('polygon').classList.toggle('rotated');
document.getElementById('marker').classList.toggle('show');
});
.rotated {
transform: rotate(-90deg);
}
polygon {
transition: all 1s;
}
.show {
display: block !important;
}
<div class="marker marker-index-0" id="marker" style="display: none;">
<h3>I should be a tooltip</h3>
</div>
<svg>
<circle cx="40" cy="122.5" r="26" fill="red"></circle>
<g class="markerG" transform="matrix(1,0,0,1,40,122.5)"><circle cx="0" cy="0" r="14" fill="#000000" style="cursor: pointer;"></circle><polygon points="1 -1 1 -7 -1 -7 -1 -1 -7 -1 -7 1 -1 1 -1 7 1 7 1 1 7 1 7 -1" fill="#ffffff"></polygon></g>
</svg>
Hope this helps!

A transition alone won't do it, because you can't do anything after it's done.
Instead, it would be a good time for you to learn CSS Animations.
Note that I applied the classes to a container involving both the polygon and the tooltip, in order to avoid synchronization errors.
document.querySelector('polygon').addEventListener('click', function() {
if(!document.getElementById('animationContainer').classList.contains("animated")) {
document.getElementById('animationContainer').classList.add("animated");
document.getElementById('animationContainer').classList.add("rotated");
} else {
document.getElementById('animationContainer').classList.toggle('rotated');
document.getElementById('animationContainer').classList.toggle('faded');
}
});

Just add the following to your event listener that rotates the svg. The rest is just css.
$('.marker-index-0').show();
Btw you have cursor pointer on the inner circle, but it only works on clicking the polygon. That's not intuitive design.

How can achieve an invisible pencil effect with SVG text? [duplicate]

I am trying to animate a text that I created and saved as SVG. So far, I've only been able to animate the stroke, but that's not what I am trying to achieve. How can I implement animation like the two examples, below?
http://codepen.io/se7ensky/pen/waoMyx
https://codepen.io/munkholm/pen/EaZJQE
Here is what I have so far:
.test {
width: 300px
/* margin:0 auto; */
}
.l1 {
animation: dash 15s 1;
stroke-linecap: round;
stroke-miterlimit: 10;
stroke-dasharray: 300;
stroke-dashoffset: 300;
animation-fill-mode: forwards;
/*fill: none;*/
}
.l2 {
stroke-dasharray: 300;
stroke-dashoffset: 300;
animation: dash 20s linear forwards;
-webkit-animation-delay: 1s;
/* Chrome, Safari, Opera */
animation-delay: 1s;
}
.l3 {
stroke-dasharray: 300;
stroke-dashoffset: 300;
animation: dash 25s linear forwards;
-webkit-animation-delay: 2.5s;
/* Chrome, Safari, Opera */
animation-delay: 2.5s;
}
.l4 {
stroke-dasharray: 300;
stroke-dashoffset: 300;
animation: dash 25s linear forwards;
-webkit-animation-delay: 4.5s;
/* Chrome, Safari, Opera */
animation-delay: 4.5s;
}
#keyframes dash {
to {
stroke-dashoffset: 0;
}
}

How the Se7ensky animation works is that it uses the standard dash animation technique, but clips the animated stroke with an outline representing the hand-drawn look of the logo.
So the standard dash animation technique works as follows. You take a standard line:
<svg>
<path d="M 10,75 L 290,75" stroke="red" stroke-width="50"/>
</svg>
Then you add a dash pattern to it and animate it's position (stroke-dashoffset).
.pen {
stroke-dasharray: 280 280;
stroke-dashoffset: 280;
animation-duration: 2s;
animation-name: draw;
animation-iteration-count: infinite;
animation-direction: alternate;
animation-timing-function: linear;
}
#keyframes draw {
from {
stroke-dashoffset: 280;
}
to {
stroke-dashoffset: 0;
}
}
<svg>
<path class="pen" d="M 10,75 L 290,75" stroke="red" stroke-width="50"/>
</svg>
Finally to get the fancy variable stroke width of the Se7ensky example, you clip that line with the outline of your logo.
So let's pretend this simple path below represents your logo:
<svg>
<path stroke="black" stroke-width="1" fill="lightgrey"
d="M 40,50
C 110,55 195,60, 265,55
C 290,55 290,85 265,85
C 195,85 110,85 40,100
C 0,100 0,50 40,50 Z"/>
</svg>
We turn that into a clipPath element and use it to trim our animated stroke to the shape of our logo:
.pen {
stroke-dasharray: 280 280;
stroke-dashoffset: 280;
animation-duration: 2s;
animation-name: draw;
animation-iteration-count: infinite;
animation-direction: alternate;
animation-timing-function: linear;
}
#keyframes draw {
from {
stroke-dashoffset: 280;
}
to {
stroke-dashoffset: 0;
}
}
<svg>
<clipPath id="logo">
<path d="M 40,50
C 110,55 195,60, 265,55
C 290,55 290,85 265,85
C 195,85 110,85 40,100
C 0,100 0,50 40,50 Z"/>
</clipPath>
<path class="pen" d="M 10,75 L 290,75" stroke="red" stroke-width="50" clip-path="url(#logo)"/>
</svg>
So to replicate their example, you'll need to add a continuous path (or paths if you want) to your SVG that represents the path that a pen would take if it were writing the letters in your logo.
Then animate that path using the dashoffset technique while clipping it with your original logo.
Update
Here's a final demo with a more realistic letter shape:
// Simple code to enable and disable the clipping path
var chk = document.getElementById("chk");
var penpath = document.getElementById("penpath");
chk.addEventListener("input", function(evt) {
if (evt.target.checked) {
penpath.classList.add("clipped");
} else {
penpath.classList.remove("clipped");
}
});
.pen {
fill: none;
stroke: red;
stroke-width: 18;
stroke-linecap: round;
stroke-dasharray: 206 206;
stroke-dashoffset: 206;
animation-duration: 2s;
animation-name: draw;
animation-iteration-count: infinite;
animation-direction: alternate;
animation-timing-function: linear;
}
.clipped {
clip-path: url(#logo);
}
#keyframes draw {
from {
stroke-dashoffset: 206;
}
to {
stroke-dashoffset: 0;
}

The example looks like a combination of svg paths and delayed animations.
This blog post by CSS-Tricks explains it pretty well (Note that the svg must have strokes for this to work):

Here's a guide on stroke-dashoffset (used on the example) that might be useful:

Combine draw in, rotate, and draw out with SVG animation

https://jsfiddle.net/u1sqa210/
I want to make a spinner that will draw in clockwise, rotate 2 full cycles at a faster rate than the draw in, then draw out counter clockwise. I have it pretty close, but I am not sure how to coordinate the rotation with the drawing animations. I usually end up with it rotation not enough, or during the draw out animation, which is not what I want.
$spinnerSize: 100;
svg.spinner {
width: $spinnerSize + px;
height: $spinnerSize + px;
x: 100px;
y: 100px;
viewBox: 0 0 $spinnerSize $spinnerSize;
circle {
fill: transparent;
stroke-width: 12;
stroke-dasharray: (3.14 * $spinnerSize);
transform-origin: (0.5px * $spinnerSize) (0.5px * $spinnerSize) 0;
animation:
spinner 3s linear infinite,
rotation 3s linear infinite;
transform: ScaleX(-1) rotate(270deg);
}
}
#keyframes spinner {
0% { stroke-dashoffset: 350; }
10% { stroke-dashoffset: 630; }
30% { stroke-dashoffset: 630; }
100% { stroke-dashoffset: 1000; }
}
#keyframes rotation
{
0% {transform: rotate(270deg)}
10% {transform: rotate(270deg)}
15% {transform: rotate(300deg)}
30% {transform: rotate(270deg)}
100% {transform: rotate(360deg);}
}
<svg class="spinner" stroke="url(#linear)">
<circle cx="50" cy="50" r="40"></circle>
<defs>
<linearGradient id="linear" x1="0%" y1="0%" x2="100%" y2="0%">
<stop offset="0%" stop-color="rgba(231,60,99,1)"/>
<stop offset="100%" stop-color="rgba(150,77,135,1)"/>
</linearGradient>
</defs>
</svg>

I think this is what you're technically asking for. I combined two animations into one:
#keyframes spinner {
0% { stroke-dashoffset: 350; transform: rotate(270deg) }
25% { stroke-dashoffset: 630; transform: rotate(270deg)}
50% { stroke-dashoffset: 630; transform: rotate(990deg)}
75% { stroke-dashoffset: 630; transform: rotate(990deg)}
100% { stroke-dashoffset: 1000; transform: rotate(990deg)}
}
