how do i make the modules on my 360 page transparent?

in the edit when u click each box to choose a colour under the colours window is a wee box to tick for transparent xx

Click at the top of your page where it says EDIT CUSTOM THEME. In the box that pops up...scroll down in it to where it lists your different modules. On the right of each one there is a box...click on that box and a color spectrum will come up. Down in the bottom left corner of that spectrum is the box you need to checkmark with the word TRANSPARENT next to it....click on it and then click the PREVEIW BUTTON to see how your page looks now. If you like it...click SAVE.
