I'm having trouble getting the height of my div element to render in percentage (%) in the CSS. Can anyone assist me with this issue?

When I try to set the "height" CSS property in percentage (%) for a div element, the HTML doesn't render anything. However, if I set the "height" CSS property using length values such as px or cm, it works perfectly fine. Can anyone provide assistance with this issue?

<html>  
    <head>  
        <meta name="viewport" content="width=device-width, initial-scale=1.0">  
    </head>  
    <body>  
        <div style="width: 40%; height: 40%; background-color: #565;">  
        </div>  
    </body>  
</html>

Answer №1

Start by ensuring that the width and height of your HTML and body elements are set to 100% in your stylesheet:

html,body{
    height:100%;
    width:100%;
}

Once you have made this adjustment, your issue should be resolved.

Answer №2

Give this a shot...

Try setting the width to 40vw and the height to 40vh.
