Please explain menu_gfx.png to me

[Jesse17]

So I opened the menu_gfx.png file and there are 4 lines, orange, blue, white, and blue.  I understand the orange line is the active button, if you offset it vertically -30px you get the blue 'mouse over' color.  My question is what are the white and second blue lines for?

[Akyhne]

Hmm, the "white" is really gray. But as so many others, you apparently have a difficulty seeing the color.

It's used for buttons such as the "Mark all messages as read" on the board index.

[Jesse17]

Oh good to know.  What's the last line for (the second blue line)  and is the white below that used for anything?

[Akyhne]

All (real) white is just transparent area. The second blue is to modify if you like want a 3rd color for hovering effect.

Great, thanks very much!

As an added note, if it helps, whenever you encounter something like that I always found it best to just search the index.css with the px offset, and look for the image file you are working with.
