I'm trying to animate an svg as if it's being written out, like this example on Codepen.

I'm trying to understand how to do this by comparing svg elements but so far I'm not seeing much difference. I replaced the svg in the codepen with my own but it wouldn't work. Why is this? And how could I make my own SVG's (such as the one below) animate in the same fashion as on the Codepen? (Besides replacing the path id!)

    Your SVG is a filled path; you need a stroke. See MDN: [Fills and Strokes](//developer.mozilla.org/docs/Web/SVG/Tutorial/Fills_and_Strokes). – Sebastian Simon Aug 18 '21 at 00:47
  • Ahhh thank you! That makes a lot more sense. Would you also be able to tell me how I'd set a beginning and end to the animation? I used stroke and got it to animate but it's now filling all over the place. – Kai Aug 18 '21 at 00:59

    1. you need a continous path like *ello* but unlike the *H* in your example. 2. You need to know the path length. You will use this as a value for stroke-dasharray and stroke-dashoffset. In order to know the path length you may use javascript and the `getTotalLength()` method – enxaneta Aug 18 '21 at 06:21

    You can also add a pathLength attribute to the path and set it =100 - which avoids having to use getTotalLength and makes it a lot easier to reason about things like % completion. – Michael Mullany Aug 18 '21 at 11:50

And how could I make my own SVG's (such as the one below) animate in the same fashion as on the Codepen? (Besides replacing the path id!)

For this you need to change your SVG

Your shapes is drawn with double paths:

enter image description here

You need to redraw the shape using single paths and make the line thicker (stroke-width ="6")

enter image description here

This is how it looks in the end:
