High cost when design errors not identified until later.

Cost of fixing mistake found in test phase = 100 x cost if found in planning phase.

Design to minimise Maintenance costs

“The goal is to provide for the needs of all

of your potential users, adapting Webtechnology to their expectations, andnever requiring the reader to simplyconform to an interface that putsunnecessary obstacles in their paths”

-Yale Style Guide

location within your web site breadcrumbs, consistent page naming, link/non-

active link colours on navigation bars provide easy return to the homepage use “navigation bars” which are easily

understood provide overview

DesignCommon Navigation Problems

Avoid inconsistency establish a visual hierarchy put navigation elements in consistent position

Avoid dead-end (orphan) pages (no link to other website pages) primary/secondary navigation bars links take opportunity to draw users into other

sections

DesignVisual design and page layout

some design conventions exist for placement of elements navigation

top and left of page(with text links repeated at bottom)

header and footer links logo top left or centre (maybe link to home

page)

DesignVisual design and page layout

short web pages home pages documents to be browsed or read on-

line pages with large images

long web pages easier to maintain easier to download or print similar to paper structure

DesignVisual design and page layout

3 layout techniques stylesheets frames (out of date) tables (XHTML only permitted for

data not layout)

2 page width options fixed width variable width – fluid layout *

DesignImages

Acceptable use not distracting not gratuitous images provide information images complement/relate to content images provide ‘brand’ identity no text in image (avoid accessibility/localisation

problems)

Speed issues - download & renderConsistency

DesignImages

Graphic file types: JPEG, GIF, PNGAdvantages of GIF All graphic web viewers support GIFs GIF supports transparency and interlacing

Advantages of JPEG Faster to download due to compression Supports full-colour images (24-bit “true colour”)

Advantages of PNG No royalty due to Unisys Increasingly popular particularly with open

source

DesignColour

Choose high contrast text/background coloursKeep colours to a minimumUse colour to unify elementsUse white space to separate elementsSymbolism in colourGlobal audiences and colourDisability and colour (10% of men are red/green colour blind)

DesignTypography - content

Style for online documents Be concise and consistent Use lists where possible

Make printing easy

DesignTypography - legibility

Line length optimal for print is 30-40 chars – line across web page is too longIncrease line spacing by 25-50%Limit no of fonts used per pageDesign for browser independent use of fonts Readability of centred text is 60% worse than left justified so avoid centeringJustified text less legible on screen so avoidCAPITALS ARE HARDER TO READ SO AVOID

DesignTypography – cross-platform

Different sizes of ‘standard fonts’ left column is PC right column is Mac

Win fonts appear 1-2 pt large than MacUse font family not just single font

DesignPage Layout

content should dominate (50-80%) important info “above the fold” place common page elements according to user expectations and conventions

DesignPage Layout

Simplify and be consistent pages (or sections) share the same

basic layout themes editorial conventions hierarchies of organisation

DesignTools

Storyboard – from TV/advertising - diagram often hand-drawn explaining what a page will look like and demonstrating the ‘look and feel’Sample proformas storyboardproforma.xls

AuthoringAuthor and test prototype

Important to identify design faults before full-scale production

AuthoringTest design using prototype

Your aim as a web designer is to make a site accessible to your target audience(s) widest audience possible
