Introducing Microsoft
Expression Web
There was a time in the not-so-distant past when a designer aiming to create Web pages needed
only a basic knowledge of Hypertext Markup Language (HTML) and a robust, reliable, and 
feature-rich text editor such as Notepad. Okay, so the latter is an exaggeration, but let’s face it.
Web pages were simple then, containing limited tags used purely for formatting fonts, setting
paragraph and line breaks, adding lists, placing images, and occasionally including tabular data.
The relative simplicity of creating Web pages, then, led to the increased visibility and use of the
Web. Gone are the days of adding a few tags to a blank document in Notepad, saving the file with
an 
.html
extension, and then opening that page within a browser to see the finished product. With
increased usage came new ways of formatting and structuring content in a Cascading Style Sheet
(CSS). Scripting languages such as JavaScript were introduced in an effort to improve the usability
of Web pages, validate forms, detect browsers, create cookies, and more. As the Web became the per-
fect medium for sharing and disseminating information, users became much more finicky, demand-
ing support for audio, video, and even animation.
Beyond these simplicities however, Web pages grew to unbelievable proportions. The Web is no
longer a simple medium used merely for informational purposes. Rather, users can now expect to
do their banking, buy cars, shop for food, collaborate, and much more, online. We now work with
Web pages that are responsible for extracting content from databases, Extensible Markup Language
(XML) files, and more.
Developing for the Web no longer involves a simple understanding of HTML, a handy text editor,
and a browser. Instead, developers are increasingly required to learn other complex technologies
such as CSS, JavaScript, ASP.NET, VB.NET, C#, SQL, XML, and much more. But, with the intro-
duction of so many Web technologies just over the last decade alone, how has the Web, and, 
more specifically, how has developing for the Web increased beyond a level that so few could
have ever predicted during the Web’s infancy? The answer lies in visual editors such as Microsoft
Expression Web.
Microsoft Expression Web facilitates the development of Web pages visually. Even better, it fosters
visual development of Web applications. While knowledge of the aforementioned Web technologies
