Why a 1930s German-Italian war would remain mainly on land

Would a 1930s war between Germany and Italy produce naval battles?

Probably very few; geography and British control of Gibraltar would keep the conflict mainly on land.

A German-Italian war arising from conflict over Austria would not naturally create a major fleet battle. The German navy would have to pass France and Spain, negotiate the English Channel or Atlantic approaches, and then enter a Mediterranean whose gateway Britain could close at Gibraltar. Commerce interference elsewhere might produce minor actions, but the main war would remain on land. Maritime geography could keep the nominal enemies from bringing their fleets into contact.
