html!
It is a very simple language to use and understand, and anybody can come up with
a simple web page within a short time using a simple text editor. A brief
history of HTML HTML 2.0 HTML 2.0 (RFC 1866) was developed by the IETF's HTML
Working Group, which closed in 1996. HTML 3.2 This is the first recommendation
for HTML by W3C which represented the consensus on HTML features for 1996. HTML
4.0 This was first released in 18 December 1997 as a W3C recommendation. In 24
April 1998, a second release was then issued with changes limited to editorial
corrections. HTML 4.01 The latest version that most people are using today. It
is a revision which fixes all the minor errors that have been found since HTML
4.0.
xml
XML is a standard, simple, self-describing way of encoding both text and data so
that content can be processed with relatively little human intervention and
exchanged acros diverse hardware, operating systems, and applications. In brief,
XML offers a widely adopted standard way of representing text and data in a
format that can be processed without much human or machine intelligence.
Information formated in XML can be exchanged across platforms, languages, and
applications, and can be used with a wide range of development tools and
utilities. XML is similar enough to HTML in its actual format (both are closely
related to the SGML markup definition language that has been an ISO standard
since 1986) so that those familiar with HTML can fairly easily pick up basic XML
knowledge. But there are two fundamental differences: Separation of form and
content -- HTML mostly consists of tags defining the appearance of text; in XML
the tags generally define the structure and content of the data, with actual
appearance specified by a specific application or an associated stylesheet. XML
is extensible -- tags can be defined by individuals or organizations for some
specific application, whereas the HTML standard tagset is defined by the World
Wide Web Consortium (W3C).
javascript
JavaScript is used to create interactive web applications supported by the
Netscape browser. JavaScript offers many of the same advantages as VBScript.
JavaScript is simple to use, lightweight, and dynamic. Developers can easily
embed code functionality for interactive applications inside a web page. The
most noticeable difference between JavaScript and VBScript is the syntax. The
syntax for JavaScript is similar to the syntax for the C++ programming language.
Since VBScript is a subset of Visual Basic for Applications, VBScript follows
the Visual Basic for Applications syntax. The Internet Explorer 3.0 supports
JavaScript directly through a scripting engine in the file jscript.dll. In fact,
you can use both VBScript and JavaScript in a single web page. Listing 2-2 shows
an example of utilizing JavaScript and VBScript in the same page. Figure 2-2
shows a sample output. In the Internet Explorer 3.0, both JavaScript and
VBScript can read and modify HTML form elements, interact with the browser, and
automate any ActiveX component. JavaScript Versus VBScript JavaScript and
VBScript have many similarities. In fact, anyone who has mastered VBScript will
find JavaScript just as easy to learn. Since the Internet Explorer supports both
languages, knowledge of the fundamentals of both is valuable. The key
differences between JavaScript and VBScript are covered in the paragraphs that
follow. Language Scalability A primary difference between VBScript and
JavaScript is scalability. Once you learn VBScript, you are well on your way to
learning Visual Basic for Applications. If you know Visual Basic or Visual Basic
for Applications, you know VBScript. Although JavaScript has similarities to
C++, it is a new language. Other Scripting Languages Because Microsoft has
designed ActiveX Scripting to be an open standard, JavaScript and VBScript may
soon be joined by other scripting languages. The Internet Explorer can support
any scripting language that takes advantage of ActiveX Scripting. Third-party
vendors may choose to design their own scripting languages.
CSS
Cascading Style Sheets or CSS are an important way to control how your Web pages
look. CSS can control the fonts, text, colors, backgrounds, margins, and layout.
But it can be very difficult to learn CSS, and some people would rather not
learn it. There are some very good reasons to learn CSS so that you can control
your Web pages look. Modify your site designs to look how you want them to look
It's easy to take a free Web template and build a website. But these templates
can be very plain or common. So your website will look like every other site on
the internet. By learning CSS you can modify pre-built templates so that they
have your colors and styles. Thus you'll have a customized website without a lot
of effort. Save money There are a lot of Web designers who will build your
website or your CSS for you. But paying someone else to maintain your website or
blog can get expensive, even if you only have them create the designs and you
then maintain the content. Knowing how to modify the CSS will save you money
when you find small problems that you can fix yourself. And as you practice,
you'll be able to fix bigger and bigger problems. Earn money Once you know CSS
really well, you can sell these services to other websites.
vbscript
What is VBScript? VBScript is a subset of Visual Basic 4.0 language. It was
developed by Microsoft to provide more processing power to Web pages. VBScript
can be used to write both server side and client side scripting. (If you already
know Visual Basic or Visual Basic for Applications (VBA), VBScript will be very
familiar. Even if you do not know Visual Basic, once you learn VBScript, you are
on your way to programming with the whole family of Visual Basic languages.if
you want to use asp you can also use vbscript as base language.
