CSS3 - 05. RGBA colours
In this video, we look at another way of setting colours in CSS. Aside from using colour names like "blue" and Hex colours like "#00FF00", CSS3 adds another colour property called the RGBA. RGBA stands for Red Green Blue Alpha, and is similar to hex colours in the sense that you use the colours red green & blue to set custom colours. The alpha is used to set the opacity value of your colour, which makes life a whole lot easier for web developers.
