Web Designing is as easy as 1-2-3, claim some of the
software tools on the market that "generate"
your pages for you. Unfortunately, many web designers
today have fallen prey to this marketing gimmick - and
the results are obvious. Every now and then, one comes
across a website that looks good with a particular browser
and a particular screen-resolution; but view it with
a different browser, and you can't even read the plain
text on the page. Worse still, given the number of operating
systems that are used by netizens worldwide, these pages
will never be seen properly by more than a half of the
intended surfers.

Now let's assume that this web page belongs to a
site that sells stuff online. The very fact that half
the users cannot even see the page, translates into
losses worth half the amount straightaway (perhaps,
even more!) I guess that makes a good case for the
raison d'?e of this article! Web Designing is, in
my opinion, a cocktail of creative skills & technical
prowess - and one is no less important than the other.
In the following lines, I have jotted down a few
points that I noticed during my online journeys, important
from the point of view of web designers. Some of them
may be taken with a pinch of salt; for it is not possible
to please everyone everytime. But most of them are
simple enough to be used as a rule of thumb.
A picture, they say, is worth a thousand words. A
picture file, alas, is also almost as big. Images,
no doubt, enhance the look of a page, but it is not
advisable to go overboard in stuffing your page with
a truckload of images. Most net-surfers use a dial-up
connection, and the average time to load a page should
be no longer than 5 seconds. If it's longer, the surfer
will most probably click away elsewhere. So, within
this time, all the images on a page must be loaded
as well. So, as a rough yardstick, keep the aggregate
page size less than 30k.
Another important point to note is that each file
on the page requires a separate HTTP request to the
server. So a lot of small images - even if they do
not add up to a lot in terms of bytes - will slow
down the loading a lot.
Even when you must use images for navigation, please
give a second thought to the users who will not be
seeing those jazzy, fantastic & truly amazing
buttons that you spent hours to design. Yes, I'm talking
of the ALT text attribute of the IMG tag. Do not forget
to provide an Alternate Text for each image that you
use for navigation. (It may be left blank for certain
images that are purely for aesthetic reasons, but
let that be an exception, rather than the rule.) Though
not obviously apparent, ALT text can help such users
immensely.
Modern browsers offer users a choice to turn off
images. This gives an idea of how troublesome the
unwanted images could be.
A couple of more attributes that make your pages
load faster are the HEIGHT and WIDTH attributes. Without
these, the browser must wait for the image to download
since it cannot know how much space to leave for them!
Navigability & functionality come before artistic
excellence. It is no use making your site a masterpiece
of art if users cannot navigate around it - even after
they reach the main page, they have no clue as to
how to go where they want to go.
Especially common, is a kind of navigation that some
people call Mystery Meat Navigation. That means, that
unless your mouse moves over an image, you have no
idea where that link might take you. Only when the
mouse hovers do you see the actual link. This is cumbersome
because users need to move their mouse all over the
place to find out which part is a link and which is
not.
Follow the K.I.S.S. principle: Keep it simple,
stupid!
Next is a very important practical suggestion: whenever
your whole page is within a TABLE, the page cannot
render (i.e., the page does not show on the screen)
unless the entire table is downloaded. You might have
noticed this on several websites, when there is no
activity for a long time, and suddenly the entire
page is visible. Hence, to avoid such a situation,
what you should do is this: Split the table up into
two tables one below the other, and let the top one
be a short table that displays just the page header
and a few navigation links. So now, immediately upon
downloading this part of the page, users can see the
page header - and this prepares them for the long
wait ahead, as well as keeps them from leaving your
site to go to other sites, in case of a slow connection.
The ongoing browser wars have left only one
casualty -
the user. As a word of caution, stay away from all
browser-specific functions. Because if a certain feature
is supported by one browser, it will most definitely
not be supported by another. Where you must use such
features, it should not hamper the display of the
page in the other browser which does not support such
functionality. In other words, your page should degrade
gracefully.
Creating a new browser window should be the authority
of the user only. Do not try to popup new windows
to clutter the user's screen. All links must open
in the same window by default. An exception, however,
may be made for pages containing a links list. It
is convenient in such cases to open links in another
window, so that the user can come back to the links
page easily. Even in such cases, it is advisable to
give the user a prior note that links would open in
a new window.
Keep in mind the fonts-challenged users too. The
ultra-jazzy "Cloister Black MT Light" font
that looks so amazing on your machine may well be
degraded into plain old Times New Roman on your user's
machine. The reason? He/she does not have the font
installed on his/her machine - and one thing's obvious
- there's nothing you can do about the situation,
sitting halfway across the globe from them.
Stay clear of out-of-the-way hard-to-find fonts.
Use plain vanilla fonts like Arial, Verdana, Tahoma,
and Courier. If need be, make your jazzy fonts into
an image and put that on the page. (and while you're
there, do not forget Tip #1.)
A new design trick that is increasingly being used
on the web has caught my fancy: It is a very functional
navigation bar that guides you across all possible
paths within the site. It looks something like this:
Home > Section > Subsection > Page
What better than to give your users a handy way of
visiting just about any other page on your own site,
and informing them where they are!
Another new trend on the web is not all that inviting
- various vendors come up with "revolutionary
plug-ins" and undoubtedly, most amateur web designers
jump up to spruce up their pages using them. The reality
is that most people won't have them installed, and
wouldn't care about it anyway. Come to think of it,
have you seen plug-ins on any of the most popular
sites, including Yahoo.com, Amazon.com or Google.com?
It's simply not the best thing to do. Mention must
be made here of Macromedia's Shockwave Flash plug-in,
which has now made its way onto most computers today,
and thus presents no harm in using vector animation
on your site.
Java is yet another often-misused technology on webpages.
Use Java as a utilitarian programming language, not
as a graphics front-end for your photos/images. There
are various things you can do with Java; that does
not mean you should do all of them. Java applets are
known to run slower, so users experience a certain
sluggishness in performance. And worse still, Java
has been known to crash certain browsers. This is
not something everyone likes, especially if it is
done for the sole purpose of showing a set of images
in a slideshow!
The moral: Use it, but with discretion.
Never underestimate the importance of those META
tags. They can make all the difference between your
users coming to your site and going to your competitor's
- just because they couldn't find yours. Search Engines
heavily rely upon the Keywords & Description Meta
tags to populate their search database. And once again,
use discretion in writing these. Including a huge
number of keywords for the same page can spell trouble.
The description should be a small, meaningful summary
of the whole page that makes sense even when seen
out-of-context of the webpage itself, say, in a listing
of search engine results.
And the final point that summarizes all the
points so forth:
Write for all browsers, all resolutions, and all color-depths.
If you show people pages that look best with their
own browser and their own resolution, that makes them
feel "at home", and you get a better response.
Compare this with a website that proclaims "Viewed
best with Browser X at a resolution of 1024x768."
I'll give you a choice between two options when you
see such a page: download the suggested browser (which
might well be over 50 Megs), then go get a new monitor
that supports the high-resolution, and then adjust
your screen setting so you get the perfect picture.
Or simply click away to another site. Which do you
prefer?
The web waits for no one. And furthermore, the user
is king. Try your best to keep the user happy. And
to keep all users happy. For, a good website is like
a good storefront - it can mean all the difference
between a casual surfer and a serious customer.
