odd and even configuration lines does not work for me, in multiline form

Hi. I have a multiline form, and I it is difficult to identify the line where you are standing (when you go to the right of the screen). I would need to change colour of odd and even lines (didn’t worked for me), or also it would be perfect to draw a diferent line each two or three lines. How can I fix my problem? any other suggest is welcome.
Thank you very much

You can do that without programming! Go to your css settings and click through them. You will find a setting in the CSS application themese where you can set the colors for odd and even lines.
Check the Grid Line - even and Grid Line - odd or go to the advanced mode and find it there…

Thanks rr for your reply. I’ve already done that, but when I change color of even lines (for example) and save changes, odd lines are changed too, so there is no diference. What am I doing wrong?

the css is stored on your local cache. So in order to see the proper css you need to properly refresh the cache…

After that it should work fine again.

Thank you rr, but still not working after refreshing cache. Sure your suggestion is valid also in a multiline form? The strange thing is that when I make a change in odd-lines configuration (for example) I can see changes in the preview. But when I save changes, both odd and even are seved the same.
