I have customized template from template monster to show images on the menu bar when viewer is on home site:

I would like to modify my css transition to have similar transition of the first element in menu, as on the other elements > so I would like to have image openining transition on the HOME element same as on the PORTFOLIO for example.

Could anyone let me know which file should I edit? I havent that done in css files, rather in js, as I got this template from templatemonster

Hope to hear you,
