Expand widget area by default on frontpage

you can add this line to your child theme css:
#secondary {
display: block;
}

this will keep the bottom widget area open by default and the users can close it if they want.

anyone knows how to change the sidebar-link to default with a “-” symbol and not with a “+” symbol?
I have changed the bottom widget area to be open as default but now I need to change the symbol that toggles this area from open to close.

sure. sorry.
