Needing to control an element's opacity is a common occurrence in page layout.…In CSS we have two primary means of controlling transparency: the opacity…property and using the RGBA or HSLA color declarations.…So I am going to be working with the opacity.htm file, which is found in…the 08_05 directory.…Just to give you a heads-up on the structure of the page, if we scroll down, after…some descriptive text, we have a section that has three different div tags in it,…and they have a class of opacity, alpha, and background.…
If I just preview that in the browser, you can see what's happening. The div…with the background has the image in beside it, and we have a div tag on the…left-hand side that we are going to use the opacity property for.…Then we have a dig tag on the right- hand side that we are going to use…alpha transparency for. Okay.…So if I go up into my code, I can see I already have some selectors for…those two elements,…so we are just going to start adding properties directly to them.…
