  2. Lecture 4 – Overview Basic HTML • Transition to HTML5 and Key Rules • Doctype, encoding (XHTML, HTML5) • Tables, Links, Images (XHTML, HTML5) Demo of Exercise 2 • Transition from XTHML to HTML5 Web Services Google Analytics Demo Lectures – Week 4 Contenthttp://comminfo.rutgers.edu/~aspoerri/Teaching/InfoTech/Lectures.html#week4

  3. HTML – Big Picture • Page DesignProgressive Enhancement • Create HTML structure  Add CSS  Add JavaScript • Transition to HTML5  Markup with Meaning • HTML 4, XHTML: use tags to structure the content • HTML5: use tags to structure and describe meaning of content • New semantic elements: <header>, <nav>, <main>, <article> , <section>, <figure>, <aside>, <footer> • Redefines existing tags or eliminates others • More forgiving than XHTML: /> optional and <b> and <i> are back • Still true and necessary • HTML elements must be properly nested • HTML elements should have closing tag

Images • <img> image tag • Use Attributes and Values (src and alt are required to be valid HTML) • <imgsrc="pathname"alt="my image" [text to appear if image does not show]height="100" width="100" [improves time to load page] • align="left" [image floats on left, text flows on right … deprecated in HTML5 for CSS]hspace="5" [deprecated in HTML5 for CSS] vspace="5" [deprecated in HTML5 for CSS] • /> [XHTML requires />] • Floating image needs to be placed right before text that needs to flow or wrap around it.

  12. Exercise 2 • Exercise 2: HTML– Create Information Resource • Create at least 3 web pages. • Use a table to structure the page so that it has: • 3 columns: 50 | 500 | 100 pixels wide • 4 rows: 50 | 50 | 500 | 50 pixels high • Each page has one h1 tag and at least one h2 tagSans-serif font is used at least one word is bolded and italized • Simple navigation structure using relative hyperlinks. • Include at least one absolute hyperlink per page. • Edit images found on flickr.com using free online tool.Embed at least one image per page and text flows around it

Exercise 2 Demo – Step 1 • Create folder = “ex2” inside your “550” folder • Open New File with Notepad++ / TextWrangler • Save as type – All files (otherwise saves it as .txt by default) • File name - ex2_page1.html • Add doctype, encoding and title and essential elements (make sure to have closing tags) • Upload File to Eden, Set Permissions, Test in Browser

  14. Exercise 2 Demo – Step 2 • Create Table • One row with three cells and height = 50 and widths as indicated in Ex2 • Add following text “1.1”, “1.2”, “1.3” to respective cells • Add Font specification so that text in table is shown Arial and dark blue • Save Page • Upload File to Eden and Test in Browser

  15. Exercise 2 Demo – Step 3 • Copy 1st Row code • Create 2nd Row by pasting copied code and customize • Height = 50 and widths as indicated in Ex2 • Add following text “2.1”, “2.2”, “2.3” to respective cells • Create 3rd Row by pasting copied code and customize • Height = 500 and widths as indicated in Ex2 • Add following text “3.1”, “3.2”, “3.3” to respective cells • Create 4th Row by pasting copied code and customize • Height = 50 and widths as indicated in Ex2 • Add following text “4.1”, “4.2”, “4.3” to respective cells • Save Page • Upload File to Eden and Test in Browser

  16. Exercise 2 Demo – Step 4 • Enter Following Content into 3rd Row and 2nd Column: Heading 1 tag “Heading1” Paragraph tag “Intro paragraph” Heading 2 tag “Heading2” Paragraph “Follow-up paragraph” • Save Page • Upload File to Eden and Test in Browser • Make sure content in 3rd row is top aligned

  17. Exercise 2 Demo – Step 5 • Find Image and Save to Hard Disk • Insert Image before “follow-up” paragraph • Specify Height, Width, Alternate Text, Left Alignment • Save Page • Upload File to Eden and Test in Browser • Make sure there is visual gap between image and text

  18. Exercise 2 Demo – Step 6 • Enter Following Content into 1st Row and 2nd Column: “Page1 | Page2” • Attach relative hyperlink to “Page1” so that it links to page “ex2_page1.html” • Attach relative hyperlink to “Page2” so that it links to page “ex2_page2.html” • Save Page • Upload File to Eden and Test in Browser • Create “ex2_page2.html” page using Save As Customize page • Upload File to Eden, Set Permissions and Test in Browser

  19. Exercise 2 Demo – Step 7 • Create “you are here” indicator in Navigation Structure • Select “PageN” on “ex2_pageN” and remove hyperlink • Select “PageN” and make it bold • Select “PageN” and set font color to red ["#FF0000"] • Save Page • Upload File to Eden and Test in Browser • You will need to Validate Your Pages usinghttp://validator.w3.org/ • [instructor will let you know which errors you can ignore]

  20. Exercise 2 – Transition from XTHML to HTML5 • What Changes • DOCTYPE and encoding • Font specification • Width and Height of Table Cell specification • Font color of “you are here” indicator specification •  Need to use CSS • body { font: 100%/1.4 Verdana, Arial, Helvetica, sans-serif; color: #000099;} • td { width: 50px; height: 50px;} • .wide1 {width: 500px;} • .wide2 { width: 100px;} • .high1 { height: 500px;} • .here { color: #FF0000;}
