Putting code in your site to make it rank better?

[Marry]

I am somewhat new to the SEO world, but I know a little bit about it. Thing is, I don't know that much. I was wondering, is it possible to put code in your html of your site and help it rank better on google and other search engines? Say post keywords in your html file and so on. Could this help? Or does it matter? And does google not like that?
