Background color in an specific page...

Due to some customization requirements I have the background-color set to transparent using override.css.
But in an specific page (the one is using ignite gallery) I need #gkComponentWrap set it to an specific color but only on this page.
I have tried to use the page suffix in template configuration (item 366, the menu ID to a suffix like color) but probably I am doing wrong or I misunderstand the way that works that.

Is there any way to do that?

Thanks for your time.

p.s.: the url is azoque2.soloparapruebas.com and the menu is Fotos/Instalaciones

Forget my question. I was a bit less lazy and looking in the forums I find the solution:

Thanks for your time and excuse me.
