How to Fade in and Out Color of Svg

How to fade in and out color of svg

Use the values attribute instead of from and to.

<svg>  <rect width="100%" height="100%">    <animate attributeName="fill" values="red;blue;red" dur="10s" repeatCount="indefinite" />  </rect></svg>

SVG fade color of object

You will want to use the radial gradient to have this work. You can play around with the offset numbers for the desired effect.

<svg height="100" width="100">
  <defs>
    <radialGradient id="myGradient">
      <stop offset="10%" stop-color="red" />
      <stop offset="95%" stop-color="black" />
    </radialGradient>
  </defs>

  <!-- using my radial gradient -->
  <circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="url('#myGradient')"/>
</svg>

Fade out after animating SVG fill color

Here is a more elegant approach using transitionend:

function fillGreen() {  $(this).css({fill : 'green', transition: "2.0s"});}
function fadeoutCheckbox() {  $(".checkbox").fadeOut('fast'); }
$('.circle')  .one('click', fillGreen)  .one('webkitTransitionEnd otransitionend oTransitionEnd msTransitionEnd transitionend', fadeoutCheckbox);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><svg class="checkbox" xmlns="http://www.w3.org/2000/svg" version="1.1">   <circle class="circle" stroke="green" stroke-width="2" cx="26" cy="26" r="25" fill="transparent"/>   <path stroke="green" stroke-width="5" fill="none" d="M14.1 27.2l7.1 7.2 16.7-16.8"/></svg>

SVG Fade in Animation

The simplest approach is to use a keyTimes attribute to control the fade in and fade out timing.

We have five arrows. The first one takes one second to fade in, then waits for the other four to fade in. Then takes one second to fade out again, and waits for the other four to do the same.

This means that the animation takes 10s in total for each arrow. And there are five key times in that animation:

• at 0s, opacity value is 0
• at 1s, opacity value is 1
• at 5s, opacity value is 1
• at 6s, opacity value is 0
• at 10s, opacity value is 0

The keyTimes attribute works in conjunction with the values attribute. It specifies at which time in the animation the opacity has to be at each value. So it needs to have the same number of values as there are in the values attribute. The other thing you need to know about keyTimes values is that its time values have to be in fractions of the duration. So for the second time above (1s), we need to use 0.1 (1s of 10s).

So our values attribute should be "0; 1; 1; 0; 0", and our keyTimes attribute will be "0; 0.1; 0.5; 0.6; 1".

Then to offset the start of each arrow's animation, we just use staggered begin times.

Fade the color of a custom SVG using Javascript/jQuery on hover

Snap.svg is a perfect solution for this.

Snap.svg is a javascript library for animating and interacting with svgs.
Their 'Getting Started' tutorial is a good place to start.

In terms of actual code, the following should help you achieve what you desire (taken from the linked tutorial):

//create a new instance of Snap, specifying the svg element to use
var s = Snap("#svg");

//load your svg as a fragment
Snap.load("yourfile.svg", function (f) {
    //you can change the colour of your polygons/paths/lines/etc
    f.selectAll("polygon").attr({fill: "#bada55"});
    
    //and then append the fragment to the page
    g = f.select("g");       
    s.append(g);

    //now we can animate the polygons/paths/lines etc
    g.selectAll("polygon").forEach(function(element){
        element.animate({fill: "#f00"}, 2000);
    });

});

Hope this helps.
The documentation explains all the available functions.

Fill SVG path with colour but on hover fade-in pattern

You can't transition fill like that because the two fills are not something that can be interpolated smoothly between.

What you need to do is have two versions of the ellipse, one on top of the other. Then either fade in or out the top one.

.visible-on-hover {  transition: opacity 400ms;  opacity: 0;}
.visible-on-hover:hover {  opacity: 1;}

svg fade-in text, fade-out text, and continue doing the same with new text, for set time-periods

You want something with keyTimes and keySplines. Like this perhaps...

<svg width="100%" height="100%" viewBox="-180 5 700 300" xmlns="w3.org/2000/svg"; xmlns:xlink="w3.org/1999/xlink"; version="1.1">   <path id="path" d="m0,110 h1100"/>       <text font-size="30" font-family="arial" fill="#ff5722">         <textPath xlink:href="#path"><tspan fill-opacity="0"><animate id="animation1" begin="0s;animation2.end" attributeName="fill-opacity" dur="5s" values="0;1;1;0" keyTimes="0;0.04;0.96;1"/>Word 1 </tspan>    </textPath>   </text>   <text font-size="30" font-family="arial" fill="#ff5722">         <textPath xlink:href="#path"><tspan fill-opacity="0"><animate id="animation2" begin="animation1.end" attributeName="fill-opacity" dur="5s" values="0;1;1;0" keyTimes="0;0.04;0.96;1"/>Word 2 </tspan>    </textPath>   </text> </svg>

How to show an svg element with an fade in?

You can use CSS @keyframes.

@keyframes stretchInFromLeft {
  0% {
    width: 100%;
  }
  100% {
    width: 0;
  }
}

img {
  max-width: 100%;
  width: 100%;
}

.wrapper {
  position: relative;
}

.overlay {
  animation: 1s ease-out 0s 1 stretchInFromLeft;
  position: absolute;
  top: 0;
  right: 0;
  
  background: #fff;
  width: 0;
  height: 100%;
}

<div class="wrapper">
  <img src="https://i.stack.imgur.com/dta2g.jpg" />
  <div class="overlay"></div>
</div>
