rgba function

Should I have to use rgb numbers to put the color for the rgba function? What if I dont know the RGB number for the specific color and I put the number #e088fd for example, or just the word#pink. How can I make the color transparent in certain percentage like rgba function?

Yes, you do have to use RGB values in the RGBA function. If you don't know what the RGB values are you can calculate them, look them up online or use a color picker function online.

Thanks, if I know the 6 digital numbers of the color, how and where can I find the RGB values though?

So if you want to calculate the values from your known hexadecimal number you simply break the number into pairs and calculate each as such: For each pair such as XY: (16*X)+Y = R, G or B. more info here http://www.pixel2life.com/publish/tutorials/164/using_php_to_convert_between_hex_and_rgb_values/

Otherwise, you can look at sites like this http://www.colorpicker.com
