RGBA是一种用于描述颜色的格式。RGBA代表着红(Red)、绿(Green)、蓝(Blue)和透明度(Alpha)，每个属性的值范围在0-255之间。通过将这四个属性的值结合起来，可以定义出任何可能的颜色。与RGB相比，RGBA还可以定义颜色的透明度，这使得它在某些场合下更为实用。RGBA格式在计算机技术中具有广泛应用。例如，...

RGBA color values are an extension of RGB color values with an Alpha channel - which specifies the opacity for a color. An RGBA color value is specified with: rgba(red,green,blue, alpha) The alpha parameter is a number between 0.0 (fully transparent) and 1.0 (not transparent at all): ...
In CSS, a color can be specified as an RGB value, using this formula:rgb(red, green, blue)Each parameter (red, green, and blue) defines the intensity of the color between 0 and 255.For example, rgb(255, 0, 0) is displayed as red, because red is set to its highest value (255)...
