Take a look at the text-only cached version of the page. If you are unsure how to do that follow my crude instructions below.
What I do to test if Googlebot can view the content of my homepage:
Do a Google search for 'site:example.com' and find your homepage. Next to the green URL in the SERP listing for your homepage there is a green arrow. Click that and select 'cached'. Then, when viewing the cached version of the homepage, click 'Text-only version' in the bottom right corner of the grey bar that appears at the top of the browser.
If the content you are questioning shows up, there is a good chance Google has obviously been able to crawl and index it. If the content is not there, there is a good chance they can't. If the content is in a hidden div it will likely still not show up in the text-only cache.
