Issues Affecting the Design of Web Sites
||Once posted, a page has to be frequently
incorporate the ever-changing web technology. Also, if the
does not maintain the links, then these too have to be checked
that the owner has not withdrawn the page.
|Speed Of Access
||This is perhaps one of the most contentious
Web design and often involves conflict. To aid the speed of
is essential that only necessary information be displayed.
images that aid usability may cause sites to download slower. It
thus be necessary to reduce the image content of a page and
it with text. An apt balance between speed and design for
should be established.
||With the Web, it IS true to say that
see is what YOU get. However, what YOU see is not
what everyone else gets. Every Web user will have different
different screen settings, different graphics cards and
computers. Designing for the average majority is the key, but
||Navigational aids such as navigational bars at
of a page, a content index, or site map on every page of the
aid usability. As many Web sites are non-linear, the use of
tools to aid
navigation around a complex site that spans over many pages is
in helping a user find their way. Link colours should be
destination of links should be obvious.
||It is possible to predict a 'possible' user
web designers are essentially designing for an 'unknown'
||These include Clarity, Accessibility,
Simplicity, Navigability, Integratability, Feedback,
Displays and Speed.
|Limitations Of HTML
||HTML structures a web page, but it is not a
tool. The use of tables, frames and tags etc allows for some
procedures, but these are not ideal. However, as technology is
constantly changing, new versions of HTML (v4.0) and DHTML (that
browsers support) are evolving, as are other techniques such as
of Java and XML etc. Also, certain typefaces are not supported,
designers use graphics instead, but these slow down the access
Thus, certain conventional design traits are unattainable.
