03. Changing Image Opacity

It's easy to change the opacity of an image in CSS.

Simply use the opacity property, and specify a decimal number from 0 to 1.0

We haven't learned pseudo-selectors yet, but just know that the :hover attribute attached to a selector gives the style when the mouse hovers over the element.

#sample {
  opacity: 1;
  height: 250px
}
  
#sample:hover {
  opacity: 0.4;
}

Try hovering over the logo to see the transparency!
