Hi @GaryStark10384,
Just quickly looking at this, it looks like you possibly have multiple CSS declarations to the same element
i.e. somewhere else there is a background-color declaration for button background-color that is over-riding your green. Check that on the right.
Try this: Instead of “;” put !important;
that way, only the !important property value will be applied to the button and all other CSS declarations will be ignored (assuming you only have one important!, lol)
So: {background-colour: green !important;}
I try to be careful with !important, and only use it when you have no alternative… you can get into issues with lots of !important. For example if you use it on a generic declaration (not a specific element) , then you may still not get the result you need, as its the order that becomes important.
Let me know if it doesn’t fix the issue, and I will take a look at it in more detail.
