  1. Today’s objectives • Review CSS Selectors • Web Development process • Review: Layout and positioning • Measurement units • Images/Photoshop

  2. Rules, Selectors, Declarations CSS

  3. The Rule Rule h1 { color : #c0c0c0; font-family : Arial; font-size : 2em; } Selector Declaration block

  4. The Declaration h1 { color : #c0c0c0; font-size : 2em; } p { font-family : Arial; } • Semicolon separates declarations • Colon separates property and values • Brackets distinguish declarations | rules

  5. Types of selectors CSS

  6. Types of selectors • Tag or HTML Selectors: Page-Wide Styling • Class Selectors: Pinpoint Control • ID Selectors: Specific Page Elements/sections • Group Selectors: h1, h2, h3, h4, h5, h6 { color : #F1CD33; } • Child selectors: div > h1 {color : blue; } • Adjacent Siblings: h1+p {color : green;} • Attribute Selectors

  7. Types of selectors | HTML | Tag h1 {color : #c0c0c0;} body {background-color : #FFFFFF;} p {padding : 10px;}

  8. Types of selectors | Classes • Classes (apply to more than one type of element) .mytext {font-family: Verdana; font-size: 14px;} <p class=“mytext”>Hello World</p> <span class=“mytext”>Learning CSS</span>

  9. Types of selectors | Dependent Classes • Dependent Classes (when the class is applied to a specific tag - .hiLight only applies to h1 element) h1.hiLight {background-color : blue;} <h1 class=“hiLight”>Hello World</h1> <h2 class=“hiLight”>Hello World</h2> <p class=“hiLight”>Hello World</p>

  10. Types of selectors | ID • ID selectors identify: • Major sections • Unique content | a rule to ONE element on a page. • Configured with #idname #banner { background-color : #FF00FF;} <div id=“banner”> </div>

  11. Types of selectors | ID • Creates a rule for an id titled “banner”. • Red, large, italic font. • Applies to ID “banner” <style type="text/css"> #banner { color : #FF0000; font-size:2em; font-style: italic; } </style> • <h1 id=“banner”> • Hello world! • </h1>

  12. HTML Tree: relationship of one element to another.

  13. HTML Tree <html> <head> <title>My Web Page</title> </head> <body> <h1>Main Topic</h1> <p> A web page about the days of the week, specifically<strong>Tuesday.</strong> </p> </body> </html>

  14. HTML Tree <html> Ancestor to all tags Ancestor to h1, p, strong <head> <body> Descendent of <html> <title> <h1> <p> Descendent of <html> and <head> Siblings <strong> Child of <p>

  15. HTML Tree • Ancestor: tag that wraps around another tag. <html> ancestor of all other tags • Descendent: A tag inside one or more tags. • Parent: tag’s closest ancestor <p><a>HOME</a></p> • Child: tag directly enclosed by another tag. <p><cite><a>HOME…</a></cite></p>

  16. Specificity | Descendent selectors • Specific descendent selectors override less specific selectors li a {color : green;} All anchors in line items are green ol li a {color : green;} Only anchors in line item in ordered lists are green

  17. Selectors | Descendent selectors p.intro { color : red;} <p class=“intro”>Hello World</p> Any paragraph with .intro class will be Red. p .intro {color : red;} <p>Hello <span class=“intro"> World</span</p> Any tag with .intro class that is in a <p> tag will be Red.

  18. Child selectors • div > h1 {color : blue; } • All heading 1 that are children of div will be blue. <div> <h1>Hello world</h1> <h1>Hello everyone</h1> </div>

  19. Adjacent Siblings • A tag that appears immediately after another tag in HTML h1+p {color : green;} Paragraphs that are adjacent to heading 1 will be green.

  20. Attribute selectors

  21. Attribute Selectors • Format a tag based on any attributes it has. img[title] {border : solid 4px #EFEFEF;} <imgsrc=“image.png” title=“CO XYZ” /> All images with a title attribute will have a border

  22. Attribute Selectors | ^ and $ Format external links: a[href^="http://"] { color : yellow; } ^ - begins with Any link that begins with “http://” is yellow a[href$=".zip"] { color : green; } $ - Ends with Any link URL that ends with “zip” is green.

  23. Attribute Selectors | * img[src*="Ire"] {border : solid 5px green;} <img src="banner_Ire.png“ /> • All images where src attribute contains “Ire” get a green, solid border.

  24. Attribute Selectors | * img[src*="Ire"] {border : solid 5px green;} <img src="banner_Ire.png“ /> <img src="banner.png“ />

  25. Pseudo-Classes • a:link | a:link { color : #EFEFEF; } • a:visited | a:visited { color : #CCCCCC; } • a:hover | a:hover { color : # F33333; } • a:active | a:active {color : #B2F511;} • Hover: (these will also work) • h1:hover { color : #FFFFFF; } • .hiLite:hover { color : #FFFFFF; }

  26. Pseudo-Classes • Proper way to order four link pseudo-classes: • a:link { color: #F60; } • a:visited { color: #900; } • a:hover { color: #F33; } • a:active {color: #B2F511; } • If order is changed, the hover and active don’t work.

  27. Pseudo-elements • :first-letter – p:first-letter {font-size : 2em; font-weight: bold; color: red;} • :first-line – p:first-line { font-size : 2em; font-weight: bold; color: red;} .hiLite:first-line { text-transform: uppercase; }

  28. Pseudo-element | :first-child :first-child • the first of all children an OL may have. ol li:first-child { font-size:1.2em; } <ol> <li>Item 1</li> <li>Item 2 </li> <li>Item 3 </li> </ol>

  30. Web Design & Development process

  31. Development process • Developing a website generally involves: 1. Conceptualize and research. 2. Create and organize content. 3. Develop the “look and feel.” 4. Produce a working prototype. 5. Testing. 6. Launching the site. 7. Maintaining the site.

  32. Development process Teague (2009): • Plan site • Build site • Deploy site • Iterate the process

  33. Iterative design process • User Analysis:What to know about the users? • Task Analysis:What are users’ goals? Tasks? • Environment analysis: What are users’ surroundings and what impact do they have? • Recruiting users: Where can you find them? • Usability specifications: What specs will you choose for rating your site/software? McCracken, 2004

  34. What is involved in the process? • Identifying needs and establishing requirements • Developing alternative designs to meet these needs • Building interactive prototypes that can be communicated and assessed • Evaluating what is being built throughout the process

  35. Core characteristics of process • Users should be involved in the development of the project. • Specific usability and user goalsneed to be identified, clearly documented and agreed at the beginning of the project. • Iteration is needed through core activities.

  36. Planning

  37. Planning • Robbins (2007) suggests that before doing any development work, ask the client numerous questions related to: • resources, • goals, and, • audience – very important. Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  38. Planning • Questions to ask clients during the research phase of design. Strategy • Why are you creating this web site? • What do you expect to accomplish? • What are you offering your audience? • What do you want users to do on your web site? And after they’ve left? • What brings your visitors back? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  39. Planning: Questions for clients General Site Description • What kind of site is it? (promotional? Informational?) • What features will it have? • What are your most important messages? • Who are your competitors? What are they doing right? • What could be improved upon? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  40. Planning: Questions for clients Target Audience • Who is the primary audience? • How Internet-savvy are they? How technically savvy? • What can you determine about user’s connection speed? Platform? Monitor size? Browser use? • How often do you expect them to visit your site? • How long will they stay during an average visit? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  41. Planning : Questions for clients Content • Who is responsible for generating original content? • How will content be submitted (process and format)? • How often will the information be updated (daily, weekly, monthly)? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  42. Planning : Questions for clients Resources • What resources have been dedicated to the project (e.g., budget, staff, time)? • Does site require content management system? • Who handles maintenance? • Is there a server for your site? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  43. Planning : Questions for clients Visual design • Envisioning a certain look and feel for the site? • Do existing standards (logos and colors) need to be incorporated? • Is site part of a larger site? • What are some other web sites you like? • What do you like about them? • What sites do you NOT like? Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  44. Planning • Often large web development firms spend more time on researching and identifying clients’ needs than on any other stage of production. • They conduct case studies, interviews, and extensive market research. Source: Robbins, J.N. (2007), Learning Web Design. O’Reilly.

  45. Planning • Must be clear about your expectations and resources early on in the process, particularly when attempting to work within a budget.

  46. Analysis: Understanding problem So you examined: • Problem | Need | Context | Environment • Users • Tasks • Project Goals and objectives. Now, move to design

  47. Designing & Producing

  48. Conceptualizing design space From Analysis/ Problem Space Source: www.theaterxtremeseattle.com/

  49. Conceptualizing design space From Analysis/problem space to design space: • A thorough analysis or good understanding of the problemspace helps inform the design space

  50. Create and Organize Content • Collect and organize content • Always remember… Content is still king on the Internet
