Basic Web Design Principles
 Three things to consider when designing a
successful Web publication that will leave a
distinct impression:
1. Balance and Proximity
2. Contrast and Focus
3. Unity and Visual Identity
Chapter 2: Web Publishing Fundamentals

Balance and Proximity
Arrange Web elements symmetrically
(centered and balanced) to suggest a
conservative, safe, peaceful atmosphere
– Avoid too much symmetry
Arrange Web elements asymmetrically (off
balance) to create an fun, energetic mood
Chapter 2: Web Publishing Fundamentals

page elements create balance
and a conservative mood

page elements create an
energetic, light-hearted mood
13
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

Web Publishing Issues
Successful Web publishing includes
recognizing the following issues:
– Technical
– Legal and ethical
– Accessibility
– Usability
– Design techniques
Chapter 2: Web Publishing Fundamentals
34
Technical
 Bandwidth is the quantity of data that can be
transmitted in a specific time frame (bits per second)
– Keep file sizes to a minimum
– Adobe Photoshop can decrease image file size
• Thumbnails – miniature photo version that links to larger photos
Differences among browsers
– Graphical vs. Non-graphical display
– Browsers vary in support for HTML, CSS, and JavaScript
• ALT tag – added to <IMG SRC> ATTRIBUTE to describe the
graphic in case the graphics mode in browser is turned off.
Technical Issues
How alternative text works

Technical Issues
Monitor Resolution
– The measure of sharpness and clarity
– A pixel (picture element) is a single point in an
electronic image (96 pixels per inch default)
– Page elements display differently at different
resolutions
– Use percentages instead of pixels to define width
• Solution – use relative width tables (define width with
percentages) as opposed to fixed width tables (define
width with pixels)
