Hey, if you decide you want to do a mobile version of your site, you have two options. One is media queries, which is easier but adds more code to your css files. The second is create a "mobile version" of your site as Sammy12 mentioned.
Example of #1.
Code:
@media screen and (max-width:480) {
// Styling goes here
}
Example of #2.
Instead of yoursite.com
It could be mobile.yoursite.com.
The latter is a definitely a more intensive variation to a mobile site because it involves a completely overhauled version of your website on a sub domain. Usually mobile versions are better for enterprise business (Google, yahoo). For a personal website, I'd suggest using media queries.
It's a must simpler(easier) approach than subdomain mobile version.
