CSS Image Opacity (Transparency)

In CSS, there is no property such as transperancy. But, you can achieve transparancy by inserting a pseudo element with regular opacity the exact size of the element behind it. The CSS3 property for transparency is opacity and it is a part of the W3C CSS3 recommendation.

The opacity-level describes the transparency-level, it ranges from 0.0 to 1.0. The level 0.0 is completely transparent, 0.5 is 50% see-through and level 1.0 is not transparent. Opacity has a default initial value of 1 (100% opaque).
