Adjust the dimensions of a box by simultaneously altering both its height and width

I am looking to create a responsive box that automatically adjusts its height when the window width is resized. I have tried using Transform:Translate() to move the picture inside, but so far, the height only changes when I manually adjust the height of my windows. This has resulted in a box filled with white boxes instead of the desired effect. I prefer not to restrict myself to a specific code language for this task.

Answer №1

To scale the height of an element based on the viewport width, you can utilize the vw unit.

For example: HTML:

<html>
    <div>
    <div>
</html>

CSS:

div {
    height: 10vw;
    background-color: red;
}

JSFiddle

Answer №2

Here's a helpful JavaScript code snippet to retrieve the width of your browser window:

function getWindowWidth() {
  var myWidth = 0;
  if( typeof( window.innerWidth ) == 'number' ) {
    //For non-IE browsers
    myWidth = window.innerWidth;
  } else if( document.documentElement && ( document.documentElement.clientWidth ) )     {
    //For IE 6+ in 'standards compliant mode'
    myWidth = document.documentElement.clientWidth;
  } else if( document.body && ( document.body.clientWidth) ) {
    //For IE 4 compatibility
    myWidth = document.body.clientWidth;
  }
  return myWidth;
}

You can also use this code to handle the window resize event:

$( window ).resize(function() {
  $( "body" ).prepend( "<div>" + $( window ).width() + "</div>" );
  // Add your resizing code for elements here
});
