1. Configure condition field @ Conditional 1

2. 2. the display type of the condition field in condition configuration is range ---- @ Conditional (displayType condition = condition displayType. rang, specified rangStart frequency = Specified rang. start, specify rangEnd tables = Specified rang. end, op = op. range) 1

Requirement 1: Determine the website subject

To create a website, you must first solve the website content problem, that is, determine the website subject. PC Magazine in the United States rated ten subjects of the top 100 national famous websites in 99 years: 1st categories: online job hunting; 2nd categories: online Chat/instant information/ICQ; 3rd categories: online community/discussion/email list; 4th categories: computer technology; 5th categories: webpage/website development; 6th categories: entertainment websites; 7th categories: travel; 8th categories: Reference/information; 9th categories: Family/education; 10th categories: Life/fashion. We can refer to the classification above to continue the subdivision. If you are interested in some aspects or have a large amount of information, you can also create something that you are interested in. If you are an individual, you can have your own opinions and make your own characteristics; they do not feel bored or powerless when creating websites. Interest is the driving force behind website creation. It is difficult to design and produce excellent works without enthusiasm.

The selection of content themes should be small and refined, the positioning of themes should be small, and the content should be refined. Do not try to create an all-encompassing website. This will often lead to the loss of website features, high labor intensity, and difficulties in timely website updates. Remember: there is only first, no second on the Internet!

Method 2: select a domain name

A domain name is the name of a website on the Internet. All the construction value of a non-product-sold pure information service website depends on its website domain name. If this domain name is lost, all the preliminary work will be? Ke Qi? Br>
Currently, many personal websites rely on free personal space, and their domain names also rely on free domain names, such as Netease's virtual Domain Name Service, in fact, this is not conducive to the promotion and development of personal websites. It is not only because the window opened in a timely manner hinders the viewer's sight and goodwill, so that one can know at a glance that it is a personal website, it also hinders the transmission speed of webpages. Therefore, in my personal opinion, the first thing I need to do is to spend some money to register a domain name. An independent domain name is the first fortune of my website. It is easy to remember the domain name.

Essentials 3: master the network creation tools

The development of network technology has led to the development of the software industry. Therefore, tools and software used to create web pages are becoming more and more abundant. From the most basic HTML editor to the popular Flash interactive Web page creation tools and various Web page creation tools, the following are representative Web page Producers:

(1) HTML editor. Although HTML code is complex and it takes a lot of time to edit and debug it, it is still favored by senior website creators because of the stability, wide support, and the ability to create complex pages. Currently, there are many editors to choose from. These editors support complex page creation and advanced HTML specifications. Professional HTML editors such as Hotdog are commonly used.

(2) WYSIWYG Web Editor. Microsoft Frontpage is represented by Microsoft Frontpage. It has the same operation interface as Word and is familiar with Word functions. It can easily compile webpages with a little training. In addition, Frontpage can parse the HTML source code of the webpage and provide preview support. However, some special display functions of Frontpage cannot be implemented in other non-ie browsers. Therefore, Frontpage is a tool software suitable for beginners and intermediate website developers.

(3) The Flash interactive web page creation tool developed by Macromedia. This is a powerful interactive vector multimedia webpage creation tool. It can easily output a variety of animated webpages. It does not require any complicated operations, but is also more compact than JAVA! However, its animation effect, interaction effect, and multimedia effect are outstanding. In addition, Mp3 music can be encapsulated in Flash animation, and forms can be filled in. In addition, because the webpage files compiled by Flash are much smaller than normal webpage files, browsing speed is greatly accelerated. This is a very suitable tool for dynamic Web production.

In addition, individual website creators also need to understand the W3C HTML4.0 standard, the basic knowledge of CSS Cascading Style Sheets, and the basic knowledge of javascript and VBScript. For some of the frequently-used... the remaining full text>
