We are providing professional training
of WEB Designing.
Part I-The Web Environment:-
Browser usage overview as of this writing, the latest trend in
browser usage is the closing of the gap between Netscape Navigator and Internet
Explorer. In mid-1997, Netscape enjoyed a comfortable 70–80% of the overall
browser usage. Presently, they are
running neck-and-neck at about 40–45% of the market share each. This may be due
to the fact that IE is so integrated with the Windows operating system that new
users are using Internet Explorer by default. It may also reflect consumer
approval for the quality of the IE software.
Browser statistics change much faster than book publishing
schedules, so the statistics presented below are not necessarily meaningful;
however if you are completely unfamiliar with the typical browser breakdowns,
these statistics from the Browser Watch site should give you an idea of who’s
using what as of this writing of course.

II-HTML:-
Affecting
the Appearance of Links As we all by
now know, the linked text is blue and underlined by default and graphics are
identified by blue borders. But it doesn’t have to be that way! Changing the
color of links is easy with HTML, so you can make your links more coordinated
with your chosen site palette. Style sheets offer even more control over the
appearance of links. You should exercise some caution in changing link
appearance. The blue text and underlines have become a strong visual clue for
“click here,” so altering this formula may confuse your users. Use your
knowledge of the savvy of your target audience to guide your design decisions.
Part
III-Graphics:-
When images with colors from the full 24-bit color space are displayed
on 8-bit monitor’s browsers do the best they can to render the
image using colors in their own built-in Web Palette.
Remapping images to the Web Palette can result in unpredictable and
undesirable dithering. Not only that, sometimes flat colors shift to the
nearest web-safe colors without dithering. The algorithm for deciding which
colors to shift and which to dither differs depending on the browser brand and
version.
But because you know exactly which colors will not dither, you can
use the Web Palette to your advantage by choosing these colors in the image
creation process. It requires a little extra effort, and an adjustment to a
limited color choice, but the payoff is that you get to see your image the way
everyone else will, with fewer surprises. It gives you, not the browser,
control over whether and how the image will dither.
If you don’t care about
dithering or how your graphics appear on 8-bit monitors, then this chapter is
not for you.
The techniques in this chapter apply to graphics that use 8-bit
palettes such as GIF or PNG.
Part
IV-Multimedia and Interactivity:-
Static
audio files tend to be in common audio formats and are transferred via a
simple FTP transaction like any other web file
When
the user’s browser detects the audio file, it will either launch an external a player or use a plug-in to play the audio. Which player it uses depends on the platform, the browser, its version, and its configuration, therefore the web
site designer cannot directly control which player will be used.
Some
common Macintosh external players include Sound Machine and SoundApp. Media The player is a common player on the Windows operating system. Internet Explorer
versions 3 and higher can play many audio file formats natively. Netscape
Navigator 3.0 and higher use the Live Audio plug-in to play most audio files.
The QuickTime player is available for both platforms and as a plug-in to both
browsers.
Streaming Audio
Streaming
audio technology was developed to address the problem of unacceptable download
times. Streaming media begins playing almost immediately after the request is
made, and continues playing as the audio data is being transferred. Some
vendors offer live broadcast capabilities.
Part
V-Emerging Technologies:-
• Greater typography and page layout controls. With style sheets, you can specify
traditional typography attributes such as font size, line spacing, and letter
spacing. It also offers methods for specifying indents, margins, and element
positioning. It even uses terminology from traditional and desktop publishing
such as points and em spaces.
• Style is separate from structure. HTML is designed for indicating the
structure of a document, to which presentation is applied by the end user’s
browsing device. Over recent years, however, HTML has been extended to provide
greater control over presentation (the tag being the most infamous example).
Style sheets, when done correctly, mark the return to the original intention of
HTML by removing presentation instructions from HTML and placing them in a
separate, optional area.
• Potentially smaller documents.
Placing font specifications once at the beginning of the document instead of
using a description for every individual element can drastically cut down on
the number of characters in the document, and thus its file size. As always
with the Web, it is desirable to keep file sizes as small as possible.
• Easier site maintenance. It is possible to link multiple HTML pages to a single style sheet,
which means you can make style changes to hundreds or thousands of web pages by
editing a single file.
Part
VI-Appendixes:-
The World Wide Web Consortium (W3C) is the organization responsible
for setting the HTML standard. The W3C takes HTML advancements into
consideration when compiling the new standards. Many once-proprietary tags have
been rolled into the standard and eventually find universal browser support.
Others go by the wayside. As HTML advances and improved methods such as
Cascading Style Sheets emerge, older tags are put to rest by the W3C. The HTML
4.0 Proposed Recommendation has classified a number of HTML tags and individual
attributes as “deprecated.”
