I was trying to use SVGs to animate the logo for my personal website, but it's not working entirely as expected. In my CSS, I used stroke-dasharray and stroke-dashoffset to animate the SVG. But as you can see in the picture below, it's not "completing" the path and finishing outlining the logo.
It may not seem like a big deal but it is really noticeable on mobile devices.
I've checked to make sure that the actual SVG code is fine, which it is, and I've tried playing around with the values for the stroke-dasharray and stroke-dashoffset in the CSS but nothing seems to work.
Here is the code that I took from out of my website (also on JSFiddle at https://jsfiddle.net/jgpixel/ehkum9vx/7/):
class Component {
constructor(props, root) {
this.props = props;
this.root = root;
}
static setAttributes(attributes, element) {
for (const key in attributes) {
element.setAttribute(key, attributes[key]);
}
}
}
class WebsiteLoader extends Component {
constructor(props, root) {
super(props, root);
this.render();
}
render() {
document.body.className = 'no-scroll';
const overlay = document.createElement('div');
overlay.className = 'overlay';
const overlayContent = document.createElement('div');
overlayContent.className = 'overlay-content';
const jgLogo = this.createSVGLogo();
this.root.appendChild(overlay);
overlay.appendChild(overlayContent);
overlayContent.appendChild(jgLogo);
setTimeout(() => {
overlay.classList.add('fade-out-overlay');
document.body.classList.remove('no-scroll');
setTimeout(() => {
overlay.remove();
}, 410);
}, this.props.animationDuration);
}
