Changing styles of custom element css properties with css media

I am trying to make responsive web and I have a little issue. Whenever I want to change some custom css property based on css media, it won't apply.

For example: I am trying to change size of iron-icon based on currently active CSS media. I have following:

<iron-icon icon="battery" class="battery"></iron-icon>

and CSS:

iron-icon.battery {
  --iron-icon-height: 2.3em;
  --iron-icon-width: 2.3em;
}

@media screen and (max-width: 1000px) {
    iron-icon.battery {
      --iron-icon-height: 1.5em;
      --iron-icon-width: 1.5em;
    }
}

current output: only 1 size is selected and the other one is ignored. For example, if I open window in resolution less than 1000px wide, 1.5em is selected. When I open window with more than 1000px wide, 2.3em is selected. But when I manually change size of window while site is laoded, other @media is not applied.

Is there a way to achiev this without using javascript (I am trying to avoid setting new class and removing old)

Right now it seems like your CSS is targeting an element with the class "iron-icon" and "battery". Where in fact you want to target the element with a class of "battery".

Simply remove your dots before iron-icon.battery. 

iron-icon.battery {
  --iron-icon-height: 2.3em;
  --iron-icon-width: 2.3em;
}

@media screen and (max-width: 1000px) {
    iron-icon.battery {
      --iron-icon-height: 1.5em;
      --iron-icon-width: 1.5em;
    }
}
