## Description
<section id='description'>
The <code>opacity</code> property in CSS is used to adjust the opacity, or conversely, the transparency for an item.
<blockquote>A value of 1 is opaque, which isn't transparent at all.<br>A value of 0.5 is half see-through.<br>A value of 0 is completely transparent.</blockquote>
The value given will apply to the entire element, whether that's an image with some transparency, or the foreground and background colors for a block of text.

## Instructions
