The Plan for Site Development
Course Project: The “About Me” site
Throughout this course we will be building a personal site with the theme “about me” as practice for future web projects. Each class we will learn new techniques for improving and adding features to this site.
The Plan for Site Development
Three phases of building a website
Phase 1. Information Architecture
Phase 2. Design
Phase 3. Development

between the web company and the client. Define functional requirements.
• Discovery - High-level discovery meeting
• Site Map Generation - A useable sitemap is created that contains a page by page index of the content information structure in flow-chart form.
• Aggregation - Gather together as much of the core content as possible. This includes media and text.
The Plan for Site Development
Phase 2: Design • Creative Discovery - Discuss the site
audience, user needs and brand guidelines. Quality Assurance - review and progress report.
• Wireframing - List all design elements that • are to be displayed on the home page. • Generate Mockups – “Pictures” of the final
design (can be sketches or finished products). • Production ready designs - Production ready media is created and development beings.

Phase 3: Development • Technical Discovery - validate the
technology requirements.
• Technical Collaboration / Client Review Session - Client review and progress report.
data, etc.
• SEO Plan - the URL's, page titles, meta
• Template Development -Based on the production ready designs, we are ready to develop html templates, styles, and programming.

You can think of Phase 1 as the “Business Plan” for the website.
Let’s work in groups of two to fill out the:

• Aggregation - Gather together as much of the core content as possible. This includes media and text.
Gather and organize the Resources for your site
List of Links appearing on each page
List of media for each page • Animation • Sound • video
List graphics for each page •Logos •Bullets and icons
(can use place-holders)
The Plan for Site Development
Phase 2: Design • Creative Discovery - Discuss the site audience, user
needs and brand guidelines.
• Quality Assurance - review and progress report.
Logo creation and optimization
Branding the site: • • Color scheme choices • Determine who the expected users are (Customers? Employers? Readers? Friends?)
Logo designs • What are others in your industry doing? • Can you use symbols? Google images is a great tool to help you answer these questions.
Color schemes • What looks good? • What are other companies doing note: red/blue are common in IT, blue/purple/light blue are common in healthcare, orange/brown is common in photography)
Note how color schemes for logos and website vary by industry.
Why do you think that might be?
How do certain colors make you feel?
Color schemes Color associations and customer psychology
When colors are applied in unexpected ways, they can change a logos meaning! Would you buy a brown-green food?
Color schemes How does changing the website color scheme affect the page?
Color schemes Pick 3-5 colors for your page color scheme. Define them in terms of web color. Web colors are in hexadecimal, or 6-digit colors.
Color schemes hexadecimal, or 6-digit colors, used in HTML and CSS code
You can click on the foreground color in Adobe Photoshop or Illustrator to see the foreground color’s hexadecimal number.
Color schemes Sometimes the color schemes are based on photos or objects

Phase 2: Design •Wireframing - List all design elements that are to be displayed on the home page. •Generate Mockups “Pictures” of the final design (can be sketches or finished products).
Hand sketched website mockups vs. digital mockups
Usually the digital mockup is made based on the quick hand-sketch. Use the mockup to present to clients or buyers, or just to plan for your own site!

This is where we start working on real web versions of the site using HTML markup and Adobe Dreamweaver.

Note
Quick Note About File Names
Spaces will be interpreted by the web server as “%20”: My First Page.html becomes My%20First%20Page.html
On certain servers (i.e. older Linux Servers) capital letters can be changed to lower case:
MyFirstPage.html becomes myfirstpage.html
Generally use lower case file names and no spaces in web files in order to ensure that the files work properly on all web servers.
HTML vs CSS
In modern web design, HTML is used ONLY for the framework of the site. Cascading Style Sheets (CSS) is used for many of the attributes we have discussed in this lesson (font characteristics, layout, and more).
Parts of a Website – “Website Anatomy” The URL
The Root Directory is where your data that makes up your site is located. It appears at www.yourdomain.com.
It may contain both files and folders.
It may contain nested folders (folders within folders).
Parts of a Website – “Website Anatomy” The URL
Paths A path is a “map” to how to find a file on your site.
Local Paths: Assume a set location
Global Paths: Full path, can be accessed from anywhere. Contains full URL. i.e. http://www....
Parts of a Website – “Website Anatomy” The URL
You are here
Local Path:
Linking to here
Depends on WHERE you are on the site.
Link reads preservation/digital.html
You are here

Local Path:
Linking to here
Depends on WHERE you are on the site.
The code for “down a folder” is “../”
Local path: ../images/earth.jpg
Parts of a Website – “Website Anatomy” The index page
Default Root Page Each folder contains a default file (the file that shows when no directory is typed).
The file is normally named: Index.html Index.htm Index.php Index.aspx/Default.aspx **ALL FOLDERS should contain an index file!
Advanced CSS
Examples of CSS
• CSS provides a powerful and still-evolving toolkit of style properties to develop advanced Web apps, e.g.: – http://andrew-

– http://vlog.it/ – http://lab.simurai.com/monster/ – http://andrew-

CSS Selector Summary

• Pseudo-element E:pseudo-element • Attribute E[foo="hi"] (literal brackets)
CSS Style Properties
• Sufficiently expressive for fine-grained control – don’t give designers a reason to cheat
• Too many properties to cover comprehensively
(many dozens)
• We’ll focus on a few of the most important ones
– text properties – layout and positional control, including the
“box model”

Width & Height
Width and height define the width and height of an element.
div id=“box”
#box {width=“50em”}
#box {height=“auto”} #box {width=“50px”}
*Width and height can be specified in pixels, ems, percentages or set to auto
#box {width=“100%”}
#box {width=“auto”}
Float: (left, right) Float property makes elements float to the right or left of the screen, positioned where they are in the HTML. Floating allows word wrapping.
div id=“box” Here is some text which wraps around the box floated to the left.
#box {float:left; margin-right: 10px;}
Floats
• a floated element shifts out of the
•
•
q { clear: right; }

flow
if there is text beside a float, the text will
wrap around the floated element
.right_img { float: right; width: 200px; }
to escape the wrapping behavior, use
the “clear” property, which prevents
overlap of floating elements
• clear property possible values:
left, right, both, none (default)
Clear: (left, right, both) When elements are floated, they wrap around each other to form a “caravan.” The clear property detaches an element from the “caravan” and allows it to start on a new line.
div id=“box1” div id=“box2”
div id=“box3”
#box3 { background-color: white; border: 1px solid #000; clear: both;}
Border (top, right, bottom, left)
div id=“box”
#box { border: red dotted 1px;
You can define the entire border or only the top, bottom, left, or right. You can also define the border using one declaration. The code could be any of the following:
#box { border-color: red; border-style: dotted; border-width: 2px;
#box { border-top: red dotted 1px; border-bottom: red dotted 1px; border-left: red dotted 1px; border-right: red dotted 1px; }
Padding (top, right, bottom, left)
Padding is the space between the text/content and the border. You can use padding for all around the element or specify each side of the rectangle separately.
The code could be any of the following:
padding: 10px;
padding
Padding: 10px 10px;
div id=“box”
padding: 10px 10px 10px 10px;
padding-left: 10px;
padding-right: 10px;
padding-bottom: 10px;
padding-top: 10px;
Margin (top, right, bottom, left) Margin is the space outside the text/content and the border. You can use margin for all around the element or specify each side of the rectangle separately.
The code could be any of the following:
margin: 10px;
margin
or
margin: 10px 10px;
or
div id=“box”
margin: 10px 10px 10px 10px;
or
margin-left: 10px;
margin-right: 10px;
margin-bottom: 10px;
margin-top: 10px;
