I am new to WordPress but design HTML and CSS. Not so familiar with PHP, but after spending hours on the tutorials I get the idea. I started a site on wordpress.com and now I want to update the css and php files there. I do not see a place to upload files other than graphic files. Is thee a way to upload your css and php files or do I have to host away from wordpress.com to accomplish that?
I keep looking for an upload section or somehting that allows me to select files and I just can't find anything like that. Please help.
