I'm editing my website www.mundozoho.com and I wat to change the background colour of my left sidebar.
I tried to change in Manage-Settings-advanced HTML/CSS the clour of my sidebar, but the button save does not do anything. Changes are not saved.
How could I change the colour to white, or gray, or any other colour?
To make sure I'm doing ok, I attach an image where I'm trying to edit CSS
Thanks.
