Each WordPress theme is made up of a collection of templates which includes a stylesheet (style.css) and several PHP template files.
The stylesheet controls the formatting and layout of your blog theme in terms of colour, what the font looks like, where elements are position on the page and so on.
PHP (stands for PHP Hypertext Preprocessor) is the scripting language used by WordPress to create the blog pages. When a visitor goes to your blog to read content, a request is sent to your server. This request is received by the PHP programming language which obtains the required information from your MySQL database and displays it in the visitor’s web browser.
While you don’t need know how to code PHP a basic understanding of both HTML and PHP means you can make minor edits to themes using a text editor such as EditPlus. EditPlus is a text editor, HTML editor and programmer’s editor for Windows. While you could edit in NotePad, EditPlus offers many powerful features that makes it better suited for editing PHP.
For Mac Users try using Smultron; free Text Edit software designed for Macs.
Always save a backup of your themes on your hard drive so that you have the original files in case it is necessary to restore the original themes.
