Svg rect animate height from bottom to top

So I have and svg clipPath and rect inside, because I want to transfom only that rectangle inside fixed shape. And I want to change height of that recangle, it works nice, but it's fixed to top of that clipPath or svg and I want to stay it at bottom and change height from bottom to top.

This is that svg code:

<svg version="1.1" id="logo" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 505 162.7" style="enable-background:new 0 0 505 162.7;" xml:space="preserve" class="go">

  <style type="text/css">

    .D{clip-path:url(#Dobrys_1_);}



    .fill3 {

      fill:#4E7DBF;

    }

  </style>

    <rect id="D3" x="0" y="0" class="D fill3" width="90.7" data-height="125.3"></rect>

  </g>

</svg>

I'm animating that height and I created codepen, where you can see my problem:
codepen
And don't tell me please to use linerGradient, because I have multiple rectangles there.
I can't use transform: scale, because it will 'shrink' it and not 'cut' it.
Can you help me please?

Your code is working only in Chrome. Normally you can't change the value of height in CSS. As for the solution to your problem: I would use a path like this: <path id="D3" class="D fill3" d="M0,125H90.7V0H0z" /> and in Javascript I would animate the d attribute from d="M0,125H90.7V125H0z" to d="M0,125H90.7V0H0z"

And how can I modify x and y positioning, when I use translate it's just not visible on the place it should be.

As I've commented I would use a path instead of a <rect> and I would animate the d attribute like this:

The main idea is to animate a value from 130 to 0 (in this case) and use this value to update the d attribute of the path, something like this:

D.setAttributeNS(null, "d", `M0,125.3H90.7V${value}H0z`);

let rid = null;



let memory = [0, 130];

let target = memory[0];

let value = memory[1];







function updateValue() {

  let dist = target - value;

  let vel = dist / 10;

  value += vel;

  //improvement

  if (Math.abs(dist) < 0.01) {

    if (rid) {

      window.cancelAnimationFrame(rid);

      rid = null;

    }

  }

}



function updatePath() {

  D.setAttributeNS(null, "d", `M0,125.3H90.7V${value}H0z`);

}



function Frame() {

  rid = window.requestAnimationFrame(Frame);

  updateValue();

  updatePath();

}



HB.addEventListener(

  "click",

  function() {

    if (rid) {

      window.cancelAnimationFrame(rid);

      rid = null;

    }



    memory.reverse();

    target = memory[1];

    Frame();

  },

  false

);

Actually I didn't notice that it doesn't work in other browsers, thank you for pointing it out. I'll try your method when I'll get home.

And by the way, it's possible by doing it like this stackoverflow.com/a/16305817/9421094 tbh I'm not sure if it is possible, I can't test it, cause I'm on my phone now, but I hope it's possible.

As I've commented I would use a path instead of a <rect> and I would animate the d attribute like this:

The main idea is to animate a value from 130 to 0 (in this case) and use this value to update the d attribute of the path, something like this:

D.setAttributeNS(null, "d", `M0,125.3H90.7V${value}H0z`);

let rid = null;



let memory = [0, 130];

let target = memory[0];

let value = memory[1];







function updateValue() {

  let dist = target - value;

  let vel = dist / 10;

  value += vel;

  //improvement

  if (Math.abs(dist) < 0.01) {

    if (rid) {

      window.cancelAnimationFrame(rid);

      rid = null;

    }

  }

}



function updatePath() {

  D.setAttributeNS(null, "d", `M0,125.3H90.7V${value}H0z`);

}



function Frame() {

  rid = window.requestAnimationFrame(Frame);

  updateValue();

  updatePath();

}



HB.addEventListener(

  "click",

  function() {

    if (rid) {

      window.cancelAnimationFrame(rid);

      rid = null;

    }



    memory.reverse();

    target = memory[1];

    Frame();

  },

  false

);

Actually I didn't notice that it doesn't work in other browsers, thank you for pointing it out. I'll try your method when I'll get home.

And by the way, it's possible by doing it like this stackoverflow.com/a/16305817/9421094 tbh I'm not sure if it is possible, I can't test it, cause I'm on my phone now, but I hope it's possible.

Actually I didn't notice that it doesn't work in other browsers, thank you for pointing it out. I'll try your method when I'll get home.

And by the way, it's possible by doing it like this stackoverflow.com/a/16305817/9421094 tbh I'm not sure if it is possible, I can't test it, cause I'm on my phone now, but I hope it's possible.
