CSS: Apply opacity only for div background and not text


In order to make only the background color opaque but not the text within the div, we need to use RGBA color scheme instead on RGB or Hex Color code.

rgba stands for "Red Greed Blue and Alpha". Alpha is for opacity. So in order to set only the background-color opaque we need to set the alpha lower then 1.

⚡️ background:rgba(80,80,80,0.5);

and not something like,

⚡️ background:#999999;opacity :0.5;

<html>
<head>
<title>Set Opacity Example</title>
</head>
 <body>
	<div style="background:rgba(80,80,80,0.1);padding:100px">
	This text has a background that is made opaque making sure text is not.
	</div>
 </body>
</html>
