In css3, the purpose of hsla () is to define colors.
The hsla () function defines colors using hue, saturation, brightness, and transparency.
HSLA means hue, saturation, brightness and transparency (English: Hue, Saturation, Lightness, Alpha).
Hue (H) is the basic attribute of color, which is commonly referred to as the color name, such as red, yellow and so on.
Saturation (S) refers to the purity of the color, the higher the color, the purer the color, and the lower the color will gradually turn gray, taking a value of 0-100%.
The brightness (L) is 0-100%. If you increase the brightness, the color will change to white; if you decrease the brightness, the color will change to black.
The value of transparency (A) is between 0,1, which represents transparency.
