Here is an example class using CSS named colors    semi-transparent     background  yellow    opacity  0 25      This adds a background that is 25  opaque  colored  and 75  transparent   CAVEAT  Unfortunately  opacity will affect then entire element it s attached to  So if you have text in that element  it will set the text to 25  opacity too   -   The way to get past this is to use the rgba or hsla methods to indicate  transparency as part of your desired background  color   This allows you to specify the background transparency  independent from the transparency of the other items in your element   Here are 3 ways to set a blue background at 75  transparency  without affecting other elements    background  rgba 0   0   100   0 75  background  rgba 0   0   255   0 75  background  hsla 240  100   50   0 75
