Example
Set the opacity level for a <div> element:
div { opacity: 0.5;}
Try it Yourself »[1]More "Try it Yourself" examples below.
Definition and UsageThe opacity property sets the opacity level for an element.
The opacity-level describes the transparency-level, where 1 is not transparent at all, 0.5 is 50% see-through, and 0 is completely transparent.
opacity 0.2
opacity 0.5
opacity 1(default)
Note: When using the opacity property to add transparency to the background of an element, all of its child elements become transparent as well. This can make the text inside a fully transparent element hard to read. If you do not want to apply opacity to child elements, use RGBA color values instead (See "More Examples" below).
