Transparency with alpha valuesThe simplest way to add transparency to a background colour, border, or text element is using alpha values in your colour styles. background-blend-mode defines how background layers blend with the background colour behind them, and with each other. I can achieve results simply by changing the background colour and these background-blend modes. If you give more than one element the same z-index value, the one which comes last in source order will appear on top. As I closed my first article here on this day all those years ago, “Have a great holiday season!” Z’s still not dead baby, Z’s still not dead.
