I’m trying to create an HTML, maybe a div to behave like the following: Resize automatically his height to be 100% based on your window Adjust it’s width to maintain constant proportions - example width would be always equal to 4/5 of his height. I’ve been trying to configure it with css however I might need to use JavaScript. If you guys have any other solutions not in JavaScript but anything else like jQuery, I would be happy to use it as well.

Hi @fkutev22,

I’m not really into plain JavaScript so I’ll give you an example using jQuery.

$(window).resize(function(){
    $('#resizeWindow').width($('#resizeWindow').height()*4/5);
});

$(window).trigger('resize');

I’ll recommend using the above code with a div. Here is an example

<div id="resizeWindow"> </div>
