Designing and Planning Webpages
(Session 2)

Fundamentals of Web Design
Purpose of Web Design
• Inform/Educate
• Persuade
Influences on Web Design
• Technology Used by Both Target Audience and Designer
• Nature of the Content
• Economy (Budget, Time, and Scale of the Project)
• Amount and Type of Visuals Included
• Meeting Usability Objectives

The Making of a Good Design
Content is important, but content alone will not make your site
work.

The Making of a Good Design
Content is important, but content alone will not make
your site work.
Good Design is:
• Understandable
• Interesting
• Easy to use
• Uniform in look and feel
• Done from a visitor’s point of view:
WYSIWYW (What You See Is What You WANT)
4

Good Design Maxims
“Rules” are only guidelines -- no single model fits every
situation, and there is no such thing as the “right” way to
create a web site.
Remember WYSIWYW
• Web users want control over the online material --
they want to seamlessly obtain the information they
need.
• Don’t force visitors down a specific path -- give them
control.
5

Typical Website Evolution
Generation 1 -- replaces paper information
Generation 2 -- has flashy elements
Generation 3 -- is bleeding edge, causing content to suffer
Generation 4 -- content and technology are integrated
Ideally, try to skip the problems of Generations 1-3 by planning
your web site carefully.

General Methods for Design
• “Ad-hoc” Process (“seat of the pants”)
• Hastily put together
• Created on the fly
• “We need a web site TODAY”
• A methodical, well-thought process includes:
• Planning
• Quality-assurance testing
7

Pitfalls of Ad-hoc Process
• Many “under construction” banners
• Old content
• Dated design and techniques
• Errors (broken links, broken scripts)
• Convoluted logic results in a confusing site
• “Spaghetti code” in the CSS that only the original designer
understands
• Difficult to update and maintain
8

Benefits of Ad-hoc Process
Sometimes “quick and dirty” is not only good enough, it’s
the best way.
It’s useable for:
• Sites that will have a short lifespan
• Very small web sites
• Sites designed for a very specific purpose (a single
survey, a single class, a specific event, etc.)
9

Why take the time to design and test
before launching?
Although it takes a lot more time up front, a well-
thought-out web site:
• Has fewer problems
• Is more effective
• Is more understandable
• Is easier to navigate
and may end up taking less time overall to create and
maintain.
10

Pre-design Work
• Consider your organization’s mission
• Define the target audience
• Set goals for the web site
• Immediate
• Long-term
• Gather content
• Organize and establish hierarchy of content
• “Chunk” content into logical information units
11

More Pre-design Work
• Create an outline or plan for content
• Create your web site on paper first
Use a flowchart to depict how visitors will go from one
page to another
• Think about the actual HTML, PDF, graphic, sound, and
other files you will need in the site
• Where will they be placed?
• How will visitors access them?
• Organize the files logically, so that the development team
can understand the hierarchy of the web pages.
12

Influences of Technology on Design
• Browsers
Internet Explorer is the dominant browser

• Operating systems
Windows XP is the most popular operating system
• Connection speeds
75% access the Internet using broadband (DSL/T1/T3)
25% access it using narrowband (modem)

• User screen sizes
80% of users are using a display with 1024x768 pixels 13

Influences of Content on Design
• The content drives how the web site looks
• Sites designed for students look different than sites
designed for staff, which look different from sites designed
for potential faculty
• Sites designed for current employees look different than
sites designed for potential clients
• Sites designed to get people to purchase items look
different than sites designed to provide information
• Use quality content from subject matter experts
• Have site reviewed PERIODICALLY by key members (CEOs,
Department Heads, Supervisors, etc.) of the group the site
supports
• Have non-affiliated people review content for clarity
• Have others proofread for grammar. 14

Economic Considerations
Budget concerns
• Staff time for creation
• Staff time for maintenance
• In-house vs. outsourcing
15

Usability
• Browsers don’t use web sites -- people do. Don’t design
a site for a particular browser -- design a site for the
user.
• There are no generic people. Try to envision a real
person accessing your site.
• Most users absorb data visually.
• Most users will not expend effort to remember things
about how your site works.
16

Usability -- Making It Easy To Read
• Factors that affect readability
• Poor eyesight of users
• Smaller, older computer monitors as displays
• Poor color perception of users
• “Cocktail-party” effect -- lots of information on a single
web page
• Design fixes:
• Use high contrast between text and background
• Use lots of white space
• Use larger fonts
• Put key navigation buttons in the upper left
• Don’t rely on color alone to distinguish between
elements on a web page
19

Usability -- User’s Memory
• Don’t force visitors to remember how to navigate/use
the site
• Provide redundant, easily recognizable features
• Generally, have visited and unvisited links be different
colors to make it easy for users to remember where
they’ve been
• Limit the number of items in a group of choices
20

Usability -- Response Times
• The amount of time a user will wait is proportional to the
payoff. If they know there is something they want to see,
they will wait for it.
• Otherwise…
• 1 second: no major potential for interrupt
• 10 seconds: users become bored
• More than 10 seconds: user may leave
Without a progress bar or other browser feedback, users
generally will go about other business -- look at sites in
other windows, talk on the phone, etc. Designers must
provide some sort of indication as to how much longer
the download will take, if the wait will be more than 10
seconds.
21

Using Cutting-Edge Tools
• Poor reasons:
• To look cool
• To prove you can
22
• Good reasons:
– To look cool!
– To draw attention
– To maintain attention
– To enhance
information
– To inform or educate

Accessibility in Web Design
• Make the navigation clear and simple
• Use a clean visual layout with ample white space
• Use descriptive link texts (avoid using “click here” without
more information)
• Provide text equivalents for non-text elements
• Don’t rely solely on color to indicate links
• Don’t make the screen flicker
• Use plain, understandable English
• Don’t rely completely on high-tech solutions
• Use markup and style sheets -- HTML for structure and CSS
for presentation.
23

Approvals/Proofing (again!)
• Get feedback on the entire web design from:
• Other web designers (for design)
• Subject matter experts (for content)
• All represented parties, including department
heads, managers, deans, etc. (for final approval)
• Non-affiliated people (for clarity)
• Proofread for grammar -- fresh eyes may catch things
you miss!
• Validate for accessibility and compliance with W3C
guidelines

• http://validator.w3.org/
• http://cynthiasays.com/
24

Maintenance/Improvement
•Set a maintenance schedule for the site.
• Who will do the maintenance?
• What to do if emergency problems occur?
• Where will backup copies of the site be located?
•Schedule a quarterly review of the site.
• Does the content need updating?
• Is the design still working?
• Are there newer, cutting-edge tools we should be
using?
