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

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;} Hello World Learning CSS

9.  Dependent Classes (when the class is applied to a specific tag -.hiLight only applies to h1 element) h1.hiLight {background-color : blue;} Hello World Types of selectors | Dependent Classes

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;}

11. Types of selectors | ID  Creates a rule for an id titled “banner”.  Red, large, italic font.  Applies to ID “banner” #banner { color : #FF0000; font-size:2em; font-style: italic; } Hello world!

12. HTML TREE: RELATIONSHIP OF ONE ELEMENT TO ANOTHER.

13. HTML Tree My Web Page Main Topic A web page about the days of the week, specifically Tuesday.

14. HTML Tree Ancestor to all tags Ancestor to h1, p, strong Siblings Child of Descendent of Descendent of and

15. HTML Tree  Ancestor: tag that wraps around another tag. ancestor of all other tags  Descendent: A tag inside one or more tags.  Parent: tag’s closest ancestor HOME  Child: tag directly enclosed by another tag. HOME…

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;} Hello World Any paragraph with.intro class will be Red. p.intro {color : red;} Hello World Any tag with.intro class that is in a tag will be Red.

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

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;} 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;}  All images where src attribute contains “Ire” get a green, solid border.

24. Attribute Selectors | * img[src*="Ire"] {border : solid 5px green;}

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: 1. a:link { color: #F60; } 2. a:visited { color: #900; } 3. a:hover { color: #F33; } 4. 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; } Item 1 Item 2 Item 3

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): 1. Plan site 2. Build site 3. Deploy site 4. Iterate the process

33. Iterative design process 1. User Analysis: What to know about the users? 2. Task Analysis: What are users’ goals? Tasks? 3. Environment analysis: What are users’ surroundings and what impact do they have? 4. Recruiting users: Where can you find them? 5. Usability specifications: What specs will you choose for rating your site/software? McCracken, 2004

34. What is involved in the process? 1.Identifying needs and establishing requirements 2.Developing alternative designs to meet these needs 3.Building interactive prototypes that can be communicated and assessed 4.Evaluating what is being built throughout the process

35. Core characteristics of process 1.Users should be involved in the development of the project. 2.Specific usability and user goals need to be identified, clearly documented and agreed at the beginning of the project. 3.Iteration is needed through core activities.

36. PLANNING
