Animate SVG fill from left to right - css

Question

I have this SVG that I want to smoothly fill from left to right. How can I do that using CSS?
I don't want the line to be moving, i want it filling smoothly from left to right while staying in the same place, that's why i'm using svg.
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="324" height="25" viewBox="0 0 324 25">

Answer 1

You can indeed do this in CSS with the stroke property.
I'm sorry by advance, I can't use your SVG because it's a shape and in order to make your effect you only need a path without fill. So I take this SVG for the example (from this article : https://jakearchibald.com/2013/animated-line-drawing-svg/):
<svg xmlns="http://www.w3.org/2000/svg" height="98" width="581" viewBox="0 0 581 98">
<path
class="path"
d="M62.9 14.9c-25-7.74-56.6 4.8-60.4 24.3-3.73 19.6 21.6 35 39.6 37.6 42.8 6.2 72.9-53.4 116-58.9 65-18.2 191 101 215 28.8 5-16.7-7-49.1-34-44-34 11.5-31 46.5-14 69.3 9.38 12.6 24.2 20.6 39.8 22.9 91.4 9.05 102-98.9 176-86.7 18.8 3.81 33 17.3 36.7 34.6 2.01 10.2.124 21.1-5.18 30.1"
stroke="#000"
stroke-width="4.3"
fill="none">
</path>
</svg>
Notice the stroke and stroke-width properties. It's the beginning of the trick ;). Then you need to add some CSS :
.path {
//we divide the line in multiple dashes (some full and other empty)
//these dashes have 1000px in length
//so there are one dash full of 1000px of length and then one dash empty of 1000px of length and so on and so forth
stroke-dasharray: 1000;
//we change the position of the dashes
stroke-dashoffset: 1000;
//now we animate the dashoffset
//we reduce the offset of each dash so we have the impression that the dashes are moving
animation: dash 5s linear forwards;
}
#keyframes dash {
to {
stroke-dashoffset: 0;
}
}
And that's it !

Answer 2

You could work from this.
svg {
left: -400px;
position:absolute;
}
#keyframes example {
from {left: -400px;}
to {left: 200px;}
}
#-webkit-keyframes example {
from {left: -400px;}
to {left: 200px;}
}
svg {
animation-name: example;
animation-duration: 4s;
animation-delay: 2s;
animation-iteration-count: infinite;
animation-timing-function: ease-in-out;
}

Answer 3

Try this
.fadeIn {
animation-name: fade-in-left;
animation-duration: 1s;
}
#keyframes fade-in-left {
0% {
opacity: 0;
transform: translate3d(-100%, 0, 0);
}
100% {
opacity: 1;
transform: none;
}
}
