If you have worked with WordPress one of the things you notice right away is how limited the Page and Post editor is. Very simple but not a lot of tools to work with. Well there’s a reason for this in that WordPress is Blog and used to create Post entries, a picture and paragraph.
With the popularity of WordPress growing, designers continue to push the limits.
Here’s the good news, you can replace the default editor with a Plugin. There are a variety of Editors you can install that will give you further functionality. Some work fairly well others are a bit buggy.
As a designer I mostly do Page and Post design by editing the Code (the text tab). This is typically what you would need to do to achieve advanced layout and formatting.
A theme is a collection of files that work together to produce a graphical interface with an underlying unifying design for a weblog. A theme modifies the way the weblog is displayed, without modifying the underlying software. Essentially, the WordPress theme system is a way to skin your blog.
