Hello.

I try to change the standard colours in the JS Plus template. Almost all the colours can be changed easy in the css files but changing the colour of the dropdown menu gives me headaches. Everytime I try to change the RGB colour code of the dropdown menu, the menu bar changes and it looks like this:
bad.jpg (image attached)

initially it looked like this:
good.jpg (image attached)

As you can see, the position of the menu items changes. Why? I only modified the RGB colour code, nothing else.

This is the code that I change:
rgba.jpg (image attached)

The website is installed on localhost with XAMPP.

i solved the problem
i used "BlueGriffon" to edit the css files. i changed the editor program with Notepad and everything works fine.
