  4. 4. How does HTML support trees? Networks?<br />
  5. 5. Trees as nested document elements, e.g. P, TABLE, ULNetworks as hypertext elements, e.g. A, IMG<br />
  6. 6. Overview<br />Today we ...<br />Continue with our learning of HTML<br />Enhance jEdit with plugins<br />Install an FTP client to upload images<br />Create pages on STUDIO1 accounts<br />Learn basic CSS<br />

About Addresses<br />This FTP location ...<br />s<br />/home/USERID/public_html<br />... maps onto this web location<br /><br />Note:<br />Different protocol prefixes: http vssftp<br />Same machine addresses: studio1 ...<br />Different paths (but which map):<br />/~rca2t  /home/rca2t/public_html<br />
  12. 12. Exercise 1: Hello, World<br />You already have an index page in your site.<br />The URL for the page is:<br /><br />index.html is a the default page for your site; it does not need to be specified<br />Convert this page into a standard HTML page with the following structure:<br />html<br />head<br />title<br />body<br />h1<br />p<br />Give it a title “Hello, World” and and use this as the H1 text<br />

  16. 16. CSS<br />Adding Style<br />
  17. 17. CSS<br />“Cascading Style Sheets”<br />Allows you to add styles to HTML<br />Each level has its language ...<br />Styles include:<br />Font characteristics<br />Line characteristics<br />Text block <br />Background colors and images<br />Etc.<br />
  18. 18. <html><br /> <head><br /> <title>I’m an HTML document</title><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some conent</p><br /> </body><br /></html><br />Standard HTML Doc<br />
  19. 19. <html><br /> <head><br /> <title>I’m an HTML document</title><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some content:</p><br /><h1><br /><p>Some Text I want to emphasize.</p><br /></h1><br /> </body><br /></html><br />What not to do!<br />
  20. 20. <html><br /> <head><br /> <title>I’m an HTML document</title><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some conent</p><br /> <div style=“font-size:14pt;"><br /><p>Some Text I want to emphasize.</p><br /></div><br /> </body><br /></html><br />Instead, use CSS<br />
  21. 21. <html><br /> <head><br /> <title>I’m an HTML document</title><br /><style type="text/css"><br /> div {<br />font-size:14pt;<br /> font-weight:bold;<br /> }<br /> </style><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some conent</p><br /> <div><br /> <p>Some Text I want to emphasize.</p><br /></div><br /> </body><br /></html><br />Better yet, put CSS here<br />
  22. 22. <html><br /> <head><br /> <title>I’m an HTML document</title><br /><style type="text/css"><br /> .foo {<br />font-size:14pt;<br /> font-weight:bold;<br /> }<br /> </style><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some conent</p><br /> <div class=“foo”><br /><p>Some Text I want to emphasize.</p><br /></div><br /> </body><br /></html><br />with CSS in header using class attribute<br />
  23. 23. <html><br /> <head><br /> <title>I’m an HTML document</title><br /><link rel=“stylesheet” type=“text/css” href=“default.css” /><br /> </head><br /> <body><br /> <h1>Here is the first header</h1><br /> <p>Here is some conent</p><br /> <div><br /><p>Some Text I want to emphasize.</p><br /></div><br /> </body><br /></html><br />Even better: CSS in linked file<br />
  24. 24. default.css<br />.foo {<br /> font-size:14pt;<br /> font-weight:bold;<br />}<br />This is what the content of the default.css file would look like.<br />
  25. 25. CSS Syntax: Selectors<br />.foo {<br /> font-size:14pt;<br /> font-weight:bold;<br />}<br />The “selector” indicates what elements the styles apply to. Can address element names, classes, and ID.<br />
  26. 26. CSS Syntax: Selectors<br />#foo {<br /> font-size:14pt;<br /> font-weight:bold;<br />}<br />Here the selector finds an element with an ID attribute with the value “foo” …<br />e.g. <div id=“foo”>Hey.</div><br />
  27. 27. Example selectors<br />p Any p element <br /> Any p element with a class of foo<br />.foo Any element with a class of foo<br />#foo The element with an id of foo<br />
  28. 28. CSS Syntax: Declarations<br />.foo {<br /> font-size:14pt;<br /> font-weight:bold;<br />}<br />The “declarations” specify properties and values to apply to the element.<br />Form =property-name: value;<br />
  29. 29. Example Directives<br />font-family: Georgia, Garamond, serif;<br />color: blue;<br />color: #eeff99;<br />background-color: gray;<br />border: 1px solid black;<br />padding: 5px;<br />margin: 5px;<br />
  30. 30. Basic Idea<br />A CSS file is just a series of “rules”<br />A CSS rule has two parts <br />A selector to identify elements (tag name, class, id)<br />One or more declarations of style<br />CSS rules have a simple syntax<br />Selectors followed by curly braces<br />Key/value pairs separated by colons<br />Rules separated by semi-colons<br />
  31. 31. Basic idea<br />You can apply any number of rules to a document<br />Rules may appear in attributes, headers, or external files<br />Rules are “cascaded”<br />Later ones inherit previous ones<br />Later ones have precedence (can overwrite) earlier ones<br />
  32. 32. Exercise 4: Adding Style<br />Create a style element in the head of your first page<br /><style type=“text/css”><br />body {<br /> ...<br />}<br /></style><br />Change the background color of your page<br />Use the CSS list in today’s materials<br />Change the font of your header<br />
  33. 33. Exercise 5: Create a separate stylesheet<br />Create a new page in jEdit called “default.css”<br />Cut and paste the contents of your STYLE element into your new css file<br />Create a LINK element in the HEAD of each document and link to this stylesheet<br /><link rel=“stylesheet” type=“text/css” href=“default.css” /><br />Remove the STYLE elements from the HEAD of your page<br />
  34. 34. Assignment (to be posted)<br />Create a page collection in your STUDIO1 directory with the following items:<br />Main page  main1.html<br />Topic page 1  main1-topic1.html<br />Topic page 2  main1-topic2.html<br />For each page, create a TITLE element and an H1 element, titling each page as your wish.<br />In Topic page 1<br />Embed two visualizations<br />Write 250 words of context<br />In Topic page 2<br />Create a gallery of 4 images using a 2 x 2 tables<br />Create a common style sheet for each page and define font and color styles for the following elements:<br />BODY, H1, and P<br />Create a common menu in each page that links to the other pages<br />
