Example
Let us now see an example for RGBA color values −

#demo1 {background-color:rgba(108,111,35,0.6);}
#demo2 {background-color:rgba(108,111,35,0.5);}
#demo3 {background-color:rgba(108,111,35,0.4);}
#demo4 {background-color:rgba(108,111,35,0.3);}
#demo5 {background-color:rgba(108,111,35,0.2);}
#demo6 {background-color:rgba(108,111,35,0.1);}
</style>
