What is a WordPress Theme?
A WordPress Theme is a collection of files that work together to produce a graphical interface with an underlying unifying design for a website. These files are called template files. A Theme modifies the way the site is displayed, without modifying the underlying software. Themes may include customized template files, image files (*.jpg, *.gif), style sheets (*.css), custom Pages, as well as any necessary code files (*.php).
