Advantages of Web Publishing
Web publishing offers distinct advantages over
print
– Currency
– Interactivity
– Reduced production costs
– Rapid, economical delivery
Chapter 2: Web Publishing Fundamentals

The Currency Advantage
Web sites can be updated continuously and
inexpensively, while print publications are only
as current as their date of publication
To keep visitors on your site, always supply
timely, changing material

weather, stock info, news seconds after the
events occur

limitations, and load time
Chapter 2: Web Publishing Fundamentals

The Delivery Advantage
Distributing information via the Web can be
significantly faster and less expensive
With the same immediacy and cost, the Web
can reach both global and local audiences

information

Basic Web Design Principles
Three things to consider when designing a
successful Web publication that will leave a
distinct impression:
– Balance and Proximity
– Contrast and Focus
– Unity and Visual Identity
Chapter 2: Web Publishing Fundamentals
10
Balance and Proximity
Arrange Web elements symmetrically
(centered and balanced) to suggest a
conservative, safe, peaceful atmosphere
– Avoid too much symmetry (boring, uninteresting)
Arrange Web elements asymmetrically (off
balance) to create a fun, energetic mood
Chapter 2: Web Publishing Fundamentals
11
Balance and Proximity
Chapter 2: Web Publishing Fundamentals
12
Balance and Proximity
Proximity (closeness) is closely associated
with balance
Elements that have a relationship should be
placed close to each other
White space can help define proximity and
organize Web page elements

Contrast and Focus
Contrast is a mix of elements to stimulate
attention
– Use different text styles, colors, and size
Chapter 2: Web Publishing Fundamentals
15
Contrast and Focus
Focus is the center of interest or activity
A Web page needs a focal point
– This is where you want your visitors to focus their
attention
Create Web pages with contrast to elicit
awareness and establish a focal point, the
center of interest or activity
Chapter 2: Web Publishing Fundamentals

Unity and Visual Identity
Web pages and Web sites need unity, a sense
of oneness or belonging, to create the visual
identity
Create unity with consistency and repetition
throughout a Web site

Color and the Web
Color can be a powerful design tool
The color wheel can help you choose effective
and appealing color combinations
– Primary colors—red, yellow, blue
– Secondary colors—orange, green, purple
– Cool colors—green, blue, purple (tranquility)

The RGB Color System
Monitors project color using the RGB color
System
– Combines red, green, and blue light
– Levels of intensity are measured from
0 – 255
– Not all monitors can display all colors
• Web-safe palette—set of 216 of 256 colors for 8-bit
monitor
Chapter 2: Web Publishing Fundamentals

Target Audience Expectations
Certain colors have come to symbolize
particular qualities
Keep in mind the qualities generally associated
with different colors when selecting colors for
your Web site

noncommercial Web site color
schemes
Chapter 2: Web Publishing Fundamentals

Web Publishing Issues
Successful Web publishing includes
recognizing the following issues:
– Technical
– Legal and ethical
– Accessibility
– Usability
– Design techniques
Chapter 2: Web Publishing Fundamentals

Technical Issues
Bandwidth is the quantity of data that can be
transmitted in a specific time frame
– Keep file sizes to a minimum
– Corel Paint Shop Pro® or Adobe Photoshop CS3
can decrease image file size
Browser differences
– Graphical vs. Non-graphical display
• Alternative text—description for each image that loads in
a Web page in place of turned-off images
Chapter 2: Web Publishing Fundamentals
31
Technical Issues
How alternative text works
Chapter 2: Web Publishing Fundamentals
32
Technical Issues
Monitor Resolution
– The measure of sharpness and clarity
– A pixel is a single point in an electronic image
– Page elements display differently at different
resolutions
– Use percentages instead of pixels to define width
Chapter 2: Web Publishing Fundamentals
33
Legal and Privacy Issues
Copyright
– Easy to acquire images from the Web
– Make sure the material on your Web site is free of
copyright infringement

Issues
Web Accessibility
– Consider access by visitors with special needs
• Web Accessibility Initiative (WAI)—consortium of
agencies representing people with special needs

pages more accessible to people with special
needs
– Section 508—requires US govt agencies to use
accessibility technologies to ensure special needs
people can access public info
