Background:-moz-linear-gradient (left, #3992D0, Rgba (227, 157, 168, 0.5));
Left to right first parameter;
Top from top to bottom;
The second parameter is the color at which the gradient begins;
The third parameter is the color and transparency of the end of the gradient.
The so-called Rgba:
R: Red value. Positive integers | Percentage
G: Green value. Positive integers | Percentage
B: Blue value. Positive integers | Percentage
A:alpha transparency. Value between 0~1.
The first three values (red-green-blue) range from 0 to 255 integers or percentages between 0% and 100%. These values describe the amount of red, green, and blue primaries in the expected color.
If you want to set pure red, then set the red parameter full, that is 255, green, blue set 0.
The fourth value, alpha, develops the transparency/opacity of the color, which ranges from 0.0 to 1.0.
