Need a little help on Squeeze page?

I have a little problem on creating my squeeze page on wordpress, I have this socrates theme installed.

I want to create a squeeze page about my pregnancy site, and I want you people to help me on what will be my content on that squeeze page.

Any suggestion for a beginner like me?
I want a simple squeeze page with simple video, any help for a html code? and I want to create a warning box on that. theme and this is my unfinish squeeze page

Which theme? I guess you have forgotten the link so it’s very hard to make suggestions or give any help
