Adobe Dreamweaver is a web development application originally created
by Macromedia and now owned by Adobe Systems, which acquired Macromedia
in 2005.
Dreamweaver is available for both Mac and Windows operating systems. Recent versions have incorporated support for web
technologies such as CSS, JavaScript, and various server-side scripting
languages and frameworks including ASP.NET, ColdFusion, JavaServer
Pages, and PHP.
As a WYSIWYG Presto-based editor, Dreamweaver
can hide the details of pages' HTML code from the user, making it
possible for non-coders to create web pages and sites. A professional
criticism of this approach is that it produces HTML pages whose file
size and amount of HTML code is much larger than they should be, which
can cause web browsers to perform poorly. This can be particularly true
because the application makes it very easy to create table-based
layouts. In addition, some web site developers have criticized
Dreamweaver in the past for producing code that often does not comply
with W3C standards, though this has improved considerably in recent
versions. Dreamweaver 8.0 (the version prior to the recently released
9.0 within CS3) performed poorly on the Acid2 Test, developed by the
Web Standards Project. However, Macromedia has increased the support
for CSS and other ways to lay out a page without tables in later
versions of the application, with the ability to convert tables to
layers and vice versa. Dreamweaver allows users to preview websites in
many browsers, provided that they are installed on their computer. It
also has some site management tools, such as the ability to find and
replace lines of text or code by whatever parameters specified across
the entire site, and a templatization feature for creating multiple
pages with similar structures. The behaviors panel also enables use of
basic JavaScript without any coding knowledge.
Dreamweaver can
use "Extensions" - small programs, which any web developer can write
(usually in HTML and JavaScript). Extensions provide added
functionality to the software for whoever wants to download and install
them. Dreamweaver is supported by a large community of extension
developers who make extensions available (both commercial and free) for
most web development tasks from simple rollover effects to
full-featured shopping carts.
Like other HTML editors,
Dreamweaver edits files locally, then uploads all edited files to the
remote web server using FTP, SFTP, or WebDAV.
