[SOLVED] set HTML-Component to page-max - How?

hello together,
I was wondering if/how it is possible to stretch an HTML element to the entire size of the user’s browser window.
I have a leaflet map in the HTML element and would like to display it as shown in the photo:

I want to stretch the HTML component to max width and length, but I don’t know how. I have only seen in the settings, you can stretch the element to the page width, but not the height.
I would like to note that I have already read through some posts and API-Doc regarding this topic, but have not found anything about it.
Is it perhaps only possible with Editor X?

I would appreciate any help!

I have solved it:
I did it in Editor-X. I have set in my HTML component Code the style from px-values to:

<style>
    html, body, #map {
      height:100%;
      width:100%;
      padding:0px;
      margin:0px;
   } 
  </style>

then I set the html component container itself to w 100% h 100% and the strip size to 100 Viewport-Height. Now my Leaflet card automatically adjusts to any screen size!
