webpage design vs print document design
Webpage Design vs. Print Document Design

Many design principles apply to both webpages and print documents.

Apply a few fundamental principles to every webpage created.

webpage design vs print document design1
Webpage Design vs. Print Document Design

WHAT?

  • Use clear titles to capture the reader’s attention.
  • Include a title in the <head> section in case viewers bookmark your page.

WHERE?

  • Place a link to the “home” URL on at least the main pages of the site.
  • Provides connection back to where a page originated.
overall page layout
Overall Page Layout

Place the most important items or information near the top!

Be consistent in all design elements used on all pages —fonts, colors, graphic size and location, alignment, and backgrounds.

Use white space to divide the page into “chunks” of information that readers can quickly scan.

the home index page
The Home/Index Page

Creates a positive first impression of site

Communicates the purpose of the website

Place the company’s logo on the page and use it in a consistent location throughout the website.

Include navigational links or menus to provide viewers with the links they will need to navigate the website.

the home index page continued
The Home/Index PageContinued

Limit to one screen of information.

Limit amount of prose text on home page.

Show all major options on home page.

Enable access to home page from any other page on the website.

Announce changes to the website on home page.

using color
Using Color

Use contrasting colors for background and text.

Light text on dark background OR

Dark text on light background

Improves readability

text issues
Text Issues
  • Cascading Style Sheets
    • Help ensure consistency throughout the website.
    • Increase editing speed
      • Change settings of the style once to update all documents using that style
    • Similar to styles in word processor
  • Consider the intent of the site and the target audience when selecting:
  • Typefaces
  • Size
  • Alignment
  • Line length
  • Paragraphs
  • Type as a graphic
text issues typefaces
Text Issues—Typefaces

Use typefaces designed for on-screen viewing

Sans serif typefaces are easier to read on computer screens.

Use “font-family” property in styles to specify typeface.

TextIssues–Size

  • Display resolutions and operating systems vary.
    • 12 point on one machine may display as 14 point on another.
  • Windows web browsers typically display type that is 2 to 3 points larger than a Macintosh.
text issues alignment
Text Issues—Alignment

Left justified text is the most legible option for web pages.

Left margin is even and predictable.

Ragged right margin will not interfere with legibility.

Justified text is not recommended for use in webpages.

Poor spacing

Excessive hyphenation

Centered and right justified text are notrecommended.

Scanning more difficult

Ragged left margins make scanning extremely difficult

text issues continued
Text Issues Continued
  • Use indents or a blank line to indicate a new paragraph.
    • Use paragraph tag <p> in html to leave a blank line.
    • Use non-breaking spaces (&nbsp) to indent.
text issues general guidelines
Text Issues—General Guidelines

Use initial caps for headlines and headings.

Use sentence case for body text.

All caps are difficult to read.

Use italics to stress foreign words or phrases or to list book and periodical titles.

Use bold to emphasize headings.

Don’t overuse a—it will lose the effect of adding emphasis.

Do not use underlining—it implies a hyperlink.

Indicate to users when a link will move them to a page on a different website.

Add URL below the link

Add an exit disclaimer

Add an interim page warning the user that they are leaving your site and requiring them to click an additional link to leave your site.

Text as a Graphic

  • Use for banners and navigational graphics.
  • Avoid using text as a graphic for headings, subheadings and body text in case the graphic does not load properly on the viewer’s browser.

This text is really a graphic. Note that a rollover or gloss provides pop-up text.

headings and titles
Headings and Titles

Use headings that are unique from one another, descriptive and relate to the content they introduce.

Use headings in the appropriate HTML order.

Helps users get a sense of hierarchy of information on the page

Also helps users of assistive technologies understand the level of importance of information

Use a descriptive, unique, concise, and meaningful title for each webpage in the website.

Titles display in the browser’s title bar.

Titles are used by search engines to identify pages and are listed on the results page.

lists
Lists

Display a series of related items in a list.

Provide a descriptive heading for the list.

Make lists easy to scan and understand—

Meaningful labels, effective colors, borders, and white space

Capitalize first letter and first word in lists.

Bullets/Unordered List <ul> for items of equal status or value

Place important or most commonly used items at top.

Numbered/Ordered List <ol> for items where a particular order exists

Organize alphabetically or numerically.

Start numbered items at 1 rather than 0.

graphics on the web
Graphics on the Web

Use video, animation, and audio only when they help convey or support the website’s content.

Place the organization’s logo in a consistent place on every page.

Use images that add value and increase the clarity of the information on the site.

Graphics on the Web Continued

Ensure that images load quickly.

Use several small images rather than a large single image.

Include height and weight pixel dimension attributes in the image tag.

Allows layout of page to continue during download—text will fill in and space will be saved for graphics to “pour” into the reserved spaces.

Use thumbnails to preview larger images.

Use simple background images.

Can make text difficult to read

Consider solid color backgrounds instead.

multimedia

Overall considerations:

Provide controls so that users can stop, start, play, and adjust volume.

Be aware that embedded media can make total page file size very large and slow the download process.

Tags

Use object or embedded tags to include multimedia elements in page.

Use anchor tags and href attributes to link to video.

Use combinations of anchor and image tags to link to video.

Also consider the including:

  • Animation
  • Video
  • Audio
  • Slide shows
multimedia continued
Multimedia Continued

Audio

Effective, low bandwidth way to enhance content.

File sizes are smaller than video.

Do not use as much bandwidth as video.

Slide shows

Use when image quality is a top priority.

Uses a smaller file size than most video so storage and bandwidth are optimized.

Combine with audio for additional emphasis.

multimedia continued1
Multimedia Continued

Animation

GIF format

Doesn’t require special plug-in

Has no interface control.

Flash becoming dominant animation format.

Video

Use video sparingly.

Video files tend to be large.

They require more storage and slow the download speed of the webpage.

writing web content
Writing Web Content

Define acronyms and abbreviations.

Use abbreviations sparingly.

Avoid jargon.

Use familiar words.

Make first sentences descriptive.

Use active voice.

“John hit the baseball.” rather than “The baseball was hit by John.”

Minimize the number of words in sentences and the number of sentences in paragraphs.

Sentence: 20 words

Paragraph: 6 sentences

accessibility issues
Accessibility Issues

Section 508 of the Rehabilitation Act

All US government websites must meet the needs of all users including people with disabilities.

About 8% of all users have a disability that makes using a traditional website very difficult or impossible.

Vision-related, movement-related, hearing-related and learning-related are the most common.

accessibility issues continued
Accessibility Issues Continued

Provide text equivalent for non-text elements.

Ensure that all information conveyed in color is also available without color.

Provide text only pages that are useful for screen readers.

Provide equivalent alternatives for multimedia elements that are synchronized:

A text caption or auditory description of the visual track with the presentation

Do not require style sheets.
