Is there a color code for transparent in HTML?

Question

I\'m building a new website, and I\'m looking for a transparent navigation bar so the background is visible.

Answer 1

All you need is this:

#ffffff00

Here the ffffff is the color and 00 is the transparency

Also, if you want 50% transparent color, then sure you can do... #ffffff80

Where 80 is the hexadecimal equivalent of 50%. Since the scale is 0-255 in RGB Colors, the half would be 255/2 = 128, which when converted to hex becomes 80

And since in transparent we want 0 opacity, we write 00
