Dreamweaver Cs3 And Css

Cascading Style Sheets (CSS) is a W3C standard mark-up language for defining the appearance of web pages. The use of CSS allows developers to fully separate the content of the page from its presentation, speeding up the development process and also making the pages load more quickly in the browser. Whereas 20th century websites typically used tables to construct web pages and position elements, CSS now provides a cleaner and more efficient way of controlling all aspects of web page layout.

The range of computer users who have some involvement in building web pages and web sites is vast and a good many of these users choose Dreamweaver as the software tool that helps them create the web content they need without needing to become an expert on underlying technologies such as CSS. Dreamweaver CS3 includes better support for Cascading Style Sheets than previous versions. However, there is still room for improvement.

Dreamweaver CS3 is the first version of the program which assumes that the user will want to use CSS to control the layout of their web pages. To assist inexperienced and would-be web developers, each time a new page is created, the program allows the user to choose allocate a preset CSS layout to the page. There are about 30 such layouts and they come in single, double and three column varieties.

Pages created using CSS rely heavily on the use of the HTML DIV element, a multipurpose container of web content. Choosing one of the Dreamweaver CSS presets creates a page containing a series of DIV elements complete with placeholder


Dreamweaver CS4

text and the CSS code necessary to control the position and dimension of the DIVs. The placeholder text and HTML code both contain brief explanations of the techniques used and advice on how to customise these basic pages for your own purposes.

The CSS code for pages created using Dreamweaver’s preset layouts is embedded in the page itself. If a user creates a series of such pages, each one will have its own CSS code making updating very time-consuming. It is far more efficient to have all of the CSS code in one external file and link each page to this one file. At present, Dreamweaver doesn’t really make this clear to new users. However, it does have an excellent feature for moving embedded CSS code into an external file. You simply select all of the CSS definitions you wish to externalise then choose Text – CSS Styles – Move CSS Rules.

This ability to move blocks of CSS is an excellent feature but one has to ask if new users will see its significance and actually use it. The fact is that, given the increasing importance of CSS and Dreamweaver’s role as the fledgling developers best friend, the program could use some improvement in the way it handles CSS.

It is also disappointing that Dreamweaver still automatically generates CSS styles called “style1″, etc. each time the user applies a font or colour to selected text. Surely it would be easier to simply remove these basic attributes and just let the user either apply a style to the selection or, if no styles exist, create a new one. Perhaps this will be introduced in the next release of this excellent program.

Whats new in Adobe Dreamweaver CS3

Some upgrades are rip-offs, some are bug-ridden, some are too minor to worry about, but some are usually must-haves. Dreamweaver upgrades tend to fall into this last category.

Dreamweaver is used in web-development and, because the web is constantly evolving, each new Dreamweaver release usually offers features which reflect the rapidly changing environment in which the program is used. Adobe recently acquired Macromedia, the company who created Dreamweaver. So what have Adobe come up with in this their first upgrade since inheriting everybody’s favourite web development tool?

Since the release of Dreamweaver 8, way back in 2005, the use of cascading style sheets (CSS) in web page layout has become widely recognised as the way forward. However, CSS page layout coding can be a little daunting for new web designers. Dreamweaver CS3 includes a wide range of customisable CSS layouts which include useful comments for inexperienced developers explaining how the designs function. The layouts may be used not only to create individual pages but also Dreamweaver templates.

Dreamweaver CS3 has useful new features for transferring CSS code from one location to another. You can move an internal CSS definition from inside an individual page to an external style sheet. It is also possible to take inline CSS (located next to the item it described) and transfer to an external style

sheet.

One of Dreamweaver CS3’s nicest new CSS features is the ability to move CSS code form one place to another. This is particularly useful for updating pages created before CSS was used for page layout. CSS code can now be easily transferred from inside a page, both embedded style sheets and inline styles, to an external style sheet.

Dreamweaver has long had great features for integrating content with Fireworks. This new version extends a similar level of integration with the more widely-used Adobe Photoshop. Documents, slices or selections can be copied from Photoshop and pasted straight into Dreamweaver. An Image Preview window then appears in which compression and optimisation settings may be specified before the image is saved.

Dreamweaver now has support for Ajax, a programming model which uses various technologies, including JavaScript, to create fast, interactive web applications that respond to user actions by sending and receiving data to and from a server and refreshing elements of a web page without first having to reload that page. The Spry Framework, included in Dreamweaver CS3 is a collection of JavaScript code which offers developers a painless way of adding simple Ajax content to their pages.

Dreamweaver’ Spry content is divided into three categories called widgets, special effects and data sets. The widgets offer several different interface elements such as tabbed panels which allow designers to display content in a given part of the page which changes when the user clicks a particular tab. Other widgets include form validation utilities which check data entered into elements on a form and menus and sub-menus for navigation.

Spry effects can be applied to wide range of HTML components and include the ability to fade, highlight, zoom and shrink page elements in response to user interaction.

Spry data sets will bring in data from an external XML data source and display it on the page. Data sets offer a drill-down facility whereby users can click on information already displayed to bring up more detailed information on that particular item somewhere else on the page.

Adobe has not forgotten Mac users in this upgrade either. Dreamweaver CS3 now has Intel-based Mac Compatibility. This makes CS3 the first version of Dreamweaver to run natively on Intel-based Macs (as well as PowerPCs).

Whats new in Adobe Dreamweaver CS3

Many software upgrades offer poor value for money and many have bugs. However, there are some upgrades which always worth having. Adobe Dreamweaver upgrades tend to be of this type.

Dreamweaver is used in web-development and, because the web is constantly evolving, each new Dreamweaver release usually offers features which reflect the rapidly changing environment in which the program is used. Adobe recently acquired Macromedia, the company who created Dreamweaver. So what have Adobe come up with in this their first upgrade since inheriting everybody’s favourite web development tool?

Dreamweaver CS3 has useful new features for transferring CSS code from one location to another. You can move an internal CSS definition from inside an individual page to an external style sheet. It is also possible to take inline CSS (located next to the item it described) and transfer to an external style sheet.

Dreamweaver CS3’s browser compatibility check allows developers to target specific versions of all the major browsers (Firefox, Internet Explorer, Netscape, Opera, Safari) and generate a report detailing CSS-related issues with elements on the current page.

The new version of Dreamweaver now contains a great utility called the browser compatibility check. This lets you choose a particular browser, such as Internet Explorer, Opera, Firefox, Safari or Netscape, and comes up with a detailed report of any issues with the display of your CSS in the specified browser.

The fact that Dreamweaver and Photoshop are now both Adobe products is reflected a new level of compatibility between the two programs. It is now possible to make a selection in Photoshop, or to select a slice, copy it, switch to Dreamweaver and paste. The selection will automatically be converted into a web image and a new window will appear offering you a series of options for optimising the image. Dreamweaver CS3 also embraces the new Ajax technology. Ajax is a programming model which allows developers to create extremely interactive pages which are constantly refreshed with content loaded from a server but without reloading the page. Dreamweaver’s version of Ajax is through the Spry framework. This is a collection of JavaScript routines which can be inserted on the page and automatically generate all the necessary code.

Dreamweaver’ Spry content is divided into three categories called widgets, special effects and data sets. The widgets offer several different interface elements such as tabbed panels which allow designers to display content in a given part of the page which changes when the user clicks a particular tab. Other widgets include form validation utilities which check data entered into elements on a form and menus and sub-menus for navigation.

Spry data sets will bring in data from an external XML data source and display it on the page. Data sets offer a drill-down facility whereby users can click on information already displayed to bring up more detailed information on that particular item somewhere else on the page.

Dreamweaver CS3 is also the first version of the program to offer compatibility with Intel-based and PowerPC Macintosh systems. It also runs on Windows XP and Windows Vista systems.
