Recap – Web Guiding Principles
Diversity of Users & Rapid Change
– Diverse users, diverse computers, diverse skills, diverse …
– Rapid evolution of technology and expectations
– Short attention span
Common Sense
– No right way to design
Make it short
– More likely to be used and remembered
– Cut in ½ and cut in ½ again
Don't make me think
– Get rid of question marks - each item has clear purpose
Make it work at a glance
– People have little time
Support intented task - manage expectations

User Behavior  Design Implications  Design Specifics
Scan pages - don't read them
• Design for Scanning
Make text short - cut words
• Make page work at a glance
Sufficient left margin,
640x480 = main message
• Create Visual Hierarchy
Look for anything = Search Interest
Decide quickly
Choose first “reasonable item”
• Make obvious what you can do
• Make obvious what is clickable
Muddle through
Don't figure out how things work
Resist forming models
• Don't make users think
Get rid of question marks
Each item = clear purpose
1 Use Grid System
• Maintain Consistency
Helps you decide: location of primary & secondary
navigation; location and sizes of images;
location of headlines, main text, annotations etc.
• Create Visual Hierarchy & Rhythm
• Present Information Clearly & Logically
Users can read info more quickly.
Facilitates understanding and recall.
• Invisible Hand guiding users and creating
sense of place
Stick to what works
• Repetition & Consistency
Grid Layout, Easy Navigation,
Graphics, Color Coding, Typography

2 Create Visual Hierarchy & Guide Eye
• Important Things = Visually Prominent
(More Important = Larger / Sharp Contrast)
Use headlines to guide the eye
• Visual Contrast
Use sharp changes in size (headline), light intensity
(bold), color, texture, motion to create contrast.
• Proximity: related things spatially close
Spatial separation = conceptual separation.
Don't mix alignment styles.
• Use Grouping & Nesting to Increase
Information Density
(Short-term Memory = 3-7)
Use bounding shapes.

3 Typography Heuristics
• Sans Serif type is easier to read on screen
• Type size 10 -14 points
• 7 - 10 words per line
• Column width proportional to type size
• Bold and italic for small blocks of text
• Enough contrast between type & background

Writing for the Web
Concise, SCANABLE and Objective
By Jacob Nielsen
People scan page
– Study: 79% always scanned + only 16 % read word-by-word.
Make pages “scanable”
–
–
–
–
–
–
Start with conclusion
One idea per paragraph
Half the word count (or less) than conventional writing
Highlighted keywords
Meaningful sub-headings (not "clever" ones)
Bulleted lists
Credibility important and increased by:
– High-quality graphics
– Good writing
– Use of outbound hyperlinks

Dreamweaver – Create Visual Hierarchy
You can use
1
Standard Table
 Standard Mode
 Regular Columns and Rows
2
Layout Tables and Layout Cells
 Layout View
 “Irregular” Columns and Rows
to create
Layout
and
Visual Hierarchy
© Anselm Spoerri
Dreamweaver – Standard Mode
View > Table Mode > select “Standard Mode”
Certain changes must be completed in Standard mode
Format & Edit Table
and its Cells
– Format Table and Cells
– Cut, Copy or Paste Table Cell
Specify Width = Pixels or % of Browser Width
– “Accordion Effect” if specified as % of Browser Width
– If Table “Width” unspecified, then column widths unconstrained!
Layers
(future lecture)

Format Table – in “Standard Mode”
W and H fields
– Specify width & height of table as pixels or % of browser window
– If “Width” unspecified, then column widths are unconstrained!
– Usually don't need to set table height
CellPad
– Amount of space between content of a cell and cell boundary
CellSpace
– Amount of space between each layout cell
Align
– Default = “Left”
Border
– Specify in pixels thickness of border
© Anselm Spoerri
Format Table – Layout Table in “Layout Mode”
1
2
3
1
Clear Row Heights
2
Make Widths Consistent
3
–
Resets widths of each cell to match the content within that cell.
–
If width set to 400 pixels, then add content with width of 450, top bar of
table in Layout view will display: “400" (450).
Clicking "Make Widths Consistent" removes the 400-pixel setting and
keeps 450.
Remove All Spacers
–
4
Remove spacer images inserted when “autostretch” is selected
(see next slide)
Remove Nesting
–
e.g. tables within tables
Layout cells will become part of parent table
© Anselm Spoerri
4
Format Table – Layout Cell in “Layout Mode”
Fixed Width
– Specify width in pixels,
where cell width is constrained by table width
page display
Autostretch
– Resizes width automatically to fill browser window
– Displayed as wavy line in page display
– With Autostretch, transparent spacer images are inserted in fixed width
columns to control the layout.
Without spacer images, columns will change size or even visually
disappear completely if they do not contain content.
– Only one column in a layout can be Autostretch.
© Anselm Spoerri
Format Table – Layout Cell in “Layout Mode”
(cont.)
Bg
– Set Background Color of layout cell
Horz and Vert Alignment
– Specify width in pixels,
where cell width is constrained by table width
No Wrap
– If checked, then Text is not allowed to wrap
© Anselm Spoerri
Table Management
Tag Bar
(bottom border of selected file)
Use it to select specific layout elements
Clicking on <table> selects table
Clicking on <tr> selects row
Clicking on <td> selects cell
Expanded Mode
Temporarily adds cell padding and spacing to tables
and increases the tables’ borders to make editing easier.
Select View > Table Mode > Expanded Tables Mode
or
In Layout category of the Insert bar, click Expanded Tables button
© Anselm Spoerri
Editing Table – in “Standard Mode”
Cut / Copy / Paste
preserving the cells’ formatting
Single table cell
Multiple cells at once
–
Contents of the Clipboard must be compatible with structure
of table or selection in the table in which the cells will be pasted.
Insert Row / Column
–
Modify > Table > “Insert Row” or “Insert Column” or “Insert Row or Column”
(latter gives you most control)
Merge Cells
–
Modify > Table > Merge Cells
Remove cell content but leave cells intact:
–
Select one or more cells.
(Make sure the selection does not consist entirely of complete rows or columns.)
–
Choose “Edit > Clear” or press Delete.
Delete rows or columns that contain merged cells:
–
–
Select the row or column to be deleted.
Modify > Table > Delete Row / Column

Formatting Precedence – “Table Rules”
Cell Format
overwrites
Column / Row Format
overwrites
Table Format
BUT
Table Width / Height
Column
or
Row
or
constrains
Cell Width / Height
If Table “Width” unspecified, then column widths unconstrained!
© Anselm Spoerri
Dreamweaver – Table Troubleshooting
Make sure Table Width in Layout and Standard Mode Agree
– Layout Mode: Table Width = 500 pixels
– Standard Mode: Table Width = %
 Dreamweaver can “suddenly” change widths specified in “pixels” to “%”
 Good practice to double check
(especially when layout behaves strange)
© Anselm Spoerri
Text + Misc
Format Text
– Select Text
– “Properties” Window changes to “Format”
– Style, Font, Size, Color etc.
– More Control of Appearance of Text
 Remember to use Sans Serif Typeface
– Preferably set Page Font using Modify > Page Properties
Useful Features
– Visual Grid
– View > Grid > select “Show Grid” and “Snap-to-grid”
– View > Grid > Edit Grid (to edit grid)
– Tracing Image
– Modify > Page Properties: “Tracing Image” category

You can cut, copy, or paste a single table cell or multiple cells at once,
preserving the cells’ formatting.
You can paste cells at insertion point or in place of a selection in an existing table.
Pasting Multiple Table Cells
–
Clipboard content must be compatible with structure of table
or the selection in table in which the cells will be pasted.
 example
1 Open files “CopyPasteSource” and “CopyPasteDestination”
Select “CopyPasteDestination”
2 Layout Mode: create similar cell structure in interior Layout Table
as in “Source”
Select “CopyPasteSource”
