Despite the presence of frames in HTML 4.0, Web designers still rely on tables for page layout. Jennifer Heins is an Information Engineer at IBM working in the areas of Pervasive Computing and WebSphere.
Look at the HTML source of many Web pages today and you will find a vast number of tables nested one inside another with various inline colors and fonts defined. When you use frames, one frame can contain an HTML file with your site's navigation and a second frame can contain your content.
For example, in Figure 1, if you were to click on any of the links in the blue navigation area on the left, the contents in the right frame change to display the appropriate information.
The same Web page could be designed using tables, but the contents of the header, footer, and navigation area would have to be loaded repeatedly as users go to different parts of the site. Figure 2: A sample Web page using framesMinimal planning needs to be done when creating just two frames.
By default, frames can be resized by the user regardless of the frameset rows and cols attributes you define. The first time you sign in to developerWorks, a profile is created for you, so you need to choose a display name. Keep up with the best and latest technical info to help you tackle your development challenges.

However, tables are not as resource efficient as frames and they do not present information as effectively as frames can.
Besides Web development, writing, and designing samples, she enjoys architecting and implementing efficient Web information design.
Besides adding an unnecessary amount of HTML to a Web page, these tables can make a page difficult to maintain. The frame containing the navigation is only loaded into the browser once, and the navigation remains visible when users scroll through your content.
However, using frames means that the other three sections do not change and, thus, prevent resources from being spent to reload them. Also, since everything would be in one page (and one frame), the navigation and header would likely be scrolled out of view, and if the users do not scroll, they would not see the footer at all.
To explain, let's look at a basic Web page that uses two frames and go over the creation of a frameset.Whenever you see frames in a Web site there are many HTML files being used. Typically the browser default for frameborders is yes, so if you want frameborders you do not need to use this attribute.
Your display name must be unique in the developerWorks community and should not be your email address for privacy reasons. ConceptDraw PRO diagramming and vector drawing software was extended with Computer Network Diagrams Solution from the Computer and Networks Area to make your design process easier.
ConceptDraw Network Diagram is ideal for network engineers and network designers who need to draw Local Area Network diagrams, physical office network diagrams and Diagram for LAN.
We separated all the graphic documents on application areas and had produced multiple solutions for each of them.
Using the ConceptDraw collection of library objects and templates makes much easier the work on documenting the Vehicular Networks. Frames minimize unnecessary page reloads, load common parts of your site once, and reduce the amount of page scrolling.
Since 1998, Jennifer has been designing online information and information interfaces to run on various computing platforms. Further, tables typically require that each Web page on a site contain site navigation and other common pieces of site information, which means that if you want to make changes to these elements on one page, you must make that change on every page.
Also, since these frames do not change, when a user scrolls through the content in the right white frame, the information contained in the three remaining frames does not change and is always ready for use. There is always one HTML file for each frame as well as an HTML file defining the layout of the frames.
You also need to choose the size of the two frames, and decide whether you want to split the screen horizontally or vertically. A typical use of the target attribute is to have a list of links in one frame and have the linked pages open in the defined target or window.For example, an HTML page in the "nav" frame contains a link to another page that you want to open in the "content" frame.
Holzschlag describes the tremendous amount of power in using style sheets in Design Web pages with class.Check out Web Developer's Virtual Library for more information on frames, including browser specifics.


ConceptDraw provides a wide variety of examples such as flowcharts, organizational charts, business charts, UML diagrams, database and ERD, directional map, network diagrams and lots more. Find out the benefits of frames and learn the secret to your pages rendering quickly and efficiently. Her most recent attention has been on developing information and samples for mobile devices. And this marks the only limit to using frames: Do not use frames with Web content that will be primarily viewed in old browser versions. Each solution accommodates 10+ examples that shows specific application cases of a diagram. However, keep in mind that most Internet users today are either using or have access to Netscape Navigator or Microsoft Internet Explorer 4.x or higher. Cascading style sheets make it easy to manage the overall appearance of your whole frameset. Clouds are used to represent networks external to the one pictured for the purposes of depicting connections between internal and external devices, without indicating the specifics of the outside network.
Typically, LAN includes many wires and cables that demand a previously designed network diagram. Solution Browser is an application for downloading solutions with examples, templates and stencil libraries.
Often these have been provided with either their operating system or through their Internet service provider.The best way to explain frames is to look at an example.
If you are unfamiliar with cascading style sheets, check the Resources section for a helpful article.When using a style sheet, apply the default style to the frame with the most changes. Wikipedia] The global vehicular network diagram template is included in the Vehicular Networking solution from the Computer and Networks area of ConceptDraw Solution Park.
