organisations differ in:

understanding of concepts and techniques from
teaching materials

Review of Block One
Two sentence summaries of each part of Block 1
(Does NOT replace actually reading the material…)
Key Points from Block 1
Part 1
• STANDARDS allow the internet (and the web) to work
• IETF for the internet, W3C for the web
• + Others, e.g. ISO
Part 2
•
XHTML describes the CONTENT
•
CSS describes the FORMAT
o
csszengarden.com - every page has identical
CONTENT but (through CSS) a different FORMAT
Key Points from Block 1
Part 3
•
•
•
There's > 1 way to design a website...
There are attempts to measure USABILITY
BUT never forget that "content is king"!
o
Style over substance rarely true (for long) on the web
Part 4
•
ACCESSIBILITY is a good thing
•
But not necessarily easy
o
Additional effort + thought & planning
Key Points from Block 1
Part 5
•
•
Print out the CSS Box Model & pin it up!
Quality web typography isn't here yet...
Part 6
•
(Coverage of security is very light)
o
•
More to come later...
XHTML LINKS create the "web"
o
But XHTML FORMS make it "interactive"
Web Standards
“The nice thing about standards is that you have so many to
choose from.”
Andrew Tanenbaum – “Computer Networks”
Standards: How the Web Develops
- A personal view
Good Ideas
Bad Ideas
Standards Version x.a
Standards Version x.b
Bad idea
"dies out"....
(we hope!)
IE6!!
Standards Version y.a
Good Idea:
Tables (added to HTML2.0 in 1996)
Bad Idea:
Microsoft Frontpage Extensions
"Work-arounds"
Better
implementation
Work-around
"dies out"....
Work-around:
Round Corners
- At first, layout as a table with corner images
- Later, replaced by CSS features

Web Page Design
Much of what follows is subjective – your opinions may vary
Please feel free to state your view in the chat box…
Effective Design? BBC News
"I think this site has been designed very well, it is un-cluttered, clean, efficient and has good signal as
opposed to noise. It makes good use of white space, it uses one primary font (Arial I think) with
various styles to direct you straight to various headlines"
Effective Design? Guardian UK
"The useful information is displayed in the visible form without the unnecessary distraction. The
graphic elements complement the message to convey and attract the users."
Ineffective Design? Waitrose
"This is a search for Pork Sausages that returns 44 hits. I can only see 12 on each page and
between 4 & 6 on each screen. ********* Annoying. Look at all that ********** white space. Total *******
waste of my valuable *********** time and ********* ********* *********....."
Different Devices, Different Formats
•
The next three pages show the same
information presented in three different
formats
•
Consider:
o
Navigation - how does the information "flow"?
o
Use of space - how is white space used?
o
Other content - what else is in view?

onwards – Don’t worry if you haven’t read these parts yet,
you can always come back to view the recording.
What is XHTML?
• Structured ASCII Text
File
• <tag on> and <tag off>
• <head>…</head>
• <title>…</title>
• <body>…</body>
• <h1>…<h1>
• <p>…</p>
• <ol>…</ol>
• <ul>…</ul>
• <li>…</li>
Anatomy of an XHTML page
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=utf-8" />
<meta name="keywords" content="" />
<meta name="description" content="" />
<title>XHTML1.0 Valid Strict Template</title>
<link href="styles.css" rel="stylesheet" type="text/css" />
</head>
<body>
<!-- An unseen HTML comment – All content and other tags go

HTML Developments
• 1992 HTML Based on SGML
o Tagged document + DTD
• November 24, 1995 : HTML 2.0 published
o May 1996: (tables)
o August 1996: (client-side image maps)
o January 1997: (internationalization)
• January 1997 : HTML 3.2 published as a W3C Recommendation.
• December 1997 : HTML 4.0 published as a W3C Recommendation.
o Strict, in which deprecated elements are forbidden,
o Transitional, in which deprecated elements are allowed,
o Frameset, in which mostly only frame related elements are allowed;
• April 1998 : HTML 4.0 was reissued
• December 1999 : HTML 4.01 published as a W3C Recommendation.
• May 2000 : HTML 4.01 Strict published
• HTML5
• January 26, 2000. XHTML 1.1 became a W3C Recommendation on May
31, 2001.
Using CSS
•
Each XHTML tag can have associated CSS info
•
CSS has TWO major functions
•
•
Formatting
o
Set font, style, size
o
Set foreground colour
o
Set background
e.g:
o
h1 { font-family: sans-serif;
font-weight: bold; }
•
•
Layout
o
Where something appears
on the page
e.g:
o
#menu { position:
absolute; left: 10px; top:
10px; }
CSS Layout Concepts
•
In essence, very simple
•
Everything is a box
o
•
•
Boxes are either DIVs or SPANs
By default (with no CSS stylesheet) o
DIVs are arranged on the left, down the page
o
SPANs fill containing box left to right, top to bottom
Automatic assignments,
o
e.g. h1 is a DIV, words are SPANs
CSS Layout Concepts - 2
•
This is useful, because the default (nostylesheet) case does something sensible
•
Header and paragraph boxes arranged down
the left of the page
•
Words packed inside paragraph box
CSS Layout Concepts - 3
•
Or we can make boxes FLOAT, to act a bit like SPANS:
CSS Layout Concepts - 3
•
This gives us a LOT of flexibility
•
But can also cause problems!
o
o
o
o
Simple, fixed layouts, where everything is a known, fixed size
are pretty easy (e.g. forms)
The interaction of "width", "padding", and "margin" with floated
elements can have strange results
Flexible layouts, that work well with a variety of different screen
widths are VERY hard to achieve
Getting a CSS layout to work, without tools that let you actually
SEE the box model in action is almost impossible!

This is why I recommended finding the developer tools
earlier…
CSS Layout Concepts - 4
•
CSS is NOT a "silver bullet" for web layout
•
Sites need different CSS for mobile and desktop layouts
o
•
•
Well supported, but twice as much to develop
CSS cannot flow text between boxes
o
Cannot achieve true, flexible layouts like newspaper columns
o
(except by some complicated Javascript tricks)
Wouldn't it be nice to have text in a single column on a
mobile, but flow across 2 or 3 columns on a desktop /
tablet?
o
Sorry - can't be done with CSS!
Study and TMA
Guidance
Study Hints
•
•
•
•
•
Make sure you have the study guide and know
where you should be
Don’t let yourself fall behind
If you start to fall behind discuss it with your
tutor
Work on assignments as you study the material
Always plan to submit your assignments at least
3 days before the final cut-off date
Approaching TMAs
•
Study the course
o
•
Read all of the TMA instructions carefully early
in the block
o
•
Don't try and just pick out those bits you think might fit into the
TMA. You will need it all later!
Don't leave it to the end
Keep the assignment beside you as you study
the block
o
make notes as you see content that might be useful
References
• Key explanations should be in your own words to show you
understand the concepts.
• You must not use quotations to replace explanations that
should be in your own words.
• Give a reference to the source of the information that you
have used to give your own explanation.
• Give references for diagrams
• Reference in a standard way
• Quotations should be used for standards where the wording
should not be changed.
• Use quotations for important statements of opinion by
important people in this field
TMA01 Issues
•
Read the question - Answer the question!
•
Look at the marking scheme
•
o
Use this to guide your time (and word count)
o
Use headings, structure that match the mark scheme
Your tutor will validate files during marking
o
So should you!
o
http://validator.w3.org/ or browser add-ons
All TMAs submitted on or before the cut off date
WILL BE RETURNED on or before 28th
November and will be marked in the order
submitted (more or less)
