The Internet didn’t begin as an elaborate means of communication for people around the world. In fact, it was created in the 1960s as a way to transfer data between computers via telephone lines. This allowed the transfer of information to and from scientists and military personnel in a very efficient manner. It wasn’t until the early 1980s that the Internet became more readily available to doctors, educators, businesses and government agencies.

Early Web Design

By the late 1980s, the Internet was being introduced as a means of communication for anyone with a computer, modem and telephone line. In 1993, a new freeware browser program called Mosaic was developed. (continue reading…)

IE is a very good browser in many respects, but the bad guys just love to hack at it and bombard you with nasty bugs. However, there is a better browser available that’s not subject to all these viruses and attacks. Internet Explorer is the most popular browser that is used for surfing the net today.

Don’t bother with splash pages.

A splash page is normally a pointless page people put on their websites as an introduction. The page normally contains some sort of image on with a big click here to enter sign, or sometimes people don’t say anything and just hope you will click on the picture to enter their site. Splash pages are fairly pointless and it is just creating more work for your visitor as they have to click the mouse button an extra time just to see the content of your site. By removing the splash page the visitor can get to see the best parts of your site straight away, without having to wait for a pointless page to load.

Keep your navigation simple.

Wikipedia defines Web browser as a software application that enables a user to display and interact with text, images, and other information typically located on a Web page at a website on the World Wide Web or a local area network.

Structure of a web page is actually not the way it is displayed in a Web browser. A web page is written in a coded form in HTML, PHP or any other language. Web browser gets this information and formats into the display which we usually see when we visit a webpage.

Because of inherent differences in browsers the displayed page might appear slightly different in different browsers.

If you wish to see how a webpag (continue reading…)

A browser is an application that provides a way to look at and interact with all the information on the World Wide Web. Technically, a web browser uses HTTP to make requests of web servers throughout the Internet on behalf of the browser user. In other words, a web browser is a software application that allows one to view pages on the World Wide Web.

The history of the web browser can be traced back to 1991, when a computer guru named Tim Berners-Lee invented the very first web browser. It premiered on February 26, 1991, and ran on NeXSTEP. It was called WorldWideWeb, but was later renamed Nexus in an effort to avoid confusion with the World Wide Web.

There are (continue reading…)

There are many ways for implementing this concept. More than that, since the introduction of technologies such as CGI, ASP, and PHP that allow web developers to generate dynamic web pages, a lot of companies have found creative ways to develop their website applications using this concept as their foundation.

Over the past few years, the internet community has been trying to create a set of standards for creating web sites. A new technology called CSS or Cascading Style Sheets has been introduced. There is nothing actually new in the way CSS handles a web page’s presentation. CSS allows the developer to define a style for each html tag element. This is similar to the method d (continue reading…)

1/ Installation of the Opera browser:

It’s very easy to download and install Opera – as long as you know how to install any software on your favourite platform.

2/ Opera browsers main features :

- Visual tabs (tab thumbnail preview): admittedly, tabbed browsing has been a feature of Opera for a long time now. This allows users to surf the Web more easily and faster by opening multiple Web pages within the same application window and it is now standard on any modern browser.

You’ve built a Web site, you’re getting a decent amount of traffic, but you aren’t getting the kind of response that you had anticipated. Perhaps you’ve reviewed your Web site statistics and have found that nearly all of your visitors leave after viewing your home page. Asking your nephew to design your company Web site may have seemed like a good idea at the time, but there are several simple mistakes that many inexperienced developers make that can drive visitors away in droves, ultimately defeating the purpose of your Web site.

The scary news is that these problems are currently running rampant on many small-to-medium-sized companies’ Web sites, but the good news (continue reading…)
