How to get rid of this background

I have donated buttons on a wall and want to make it so there is no back round just the text and the wall

I don’t know how to get rid of the background

I tried changing the transparency of the part but that did not work

If I’m understanding what you are saying correctly, you shouldn’t change the transparency of the part, but rather the BackgroundTransparency of the TextLabel/TextButton.

I dont see an option to do that

You need to have the text label selected, not the part.
Now go to properties and scroll until you see BackgroundTransparency, then set it to 1.
