installing multiple WP sites locally with wamp question

I have been using WAMP to locally run a single wordpress site, it was all isntalled under the ‘www’ directory so that “localhost” would direct to the site in a browser.
I saw instructions on how to install multiple WP sites with WAMP that said to put everything for each WP site in separate sub-folders. So under ‘www’ i could have a folder ‘siteA’ with wordpress installed and then in a browser i would typed “localhost/siteA” to direct to the site.

I did all this and it works, however the site is now text only, no color, graphics, or images.
I am assuming that somewhere else needs to be re-routed to this new sub-folder but i have no idea what to do. Anyone know about this?
