2. HTML5 Why Learn HTML?  Learning the basics of HTML is akin to learning how to add, subtract, multiply, divide numbers, even though we have access to calculators. Without understanding how numbers work, we have no scope of making any meaningful use of numbers.  Likewise, it is essential to have a basic understanding of the underlying language of the Web (HTML) and Internet.  My expectation is that you will become aware of basic HTML, not that you will become proficient (unless you already are) in the space of a few days. So dive and try.

3. HTML5  Tools of the trade:  A free online HTML editor like the ones below http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_dd_test http://www.onlinehtmleditor.net/  Your favorite browser like Firefox or Safari or Chrome or Opera to view your masterpiece Avoid Internet Explorer (Once you have mastered the basics, then you can save your work on simple editor like Notepad or TextEdit as.txt and then.html Instructions for saving at the end of this presentation) HTML Basics

4. HTML5 Important: Read through the entire set of slides before starting

5. HTML5 Tips for Good Programming  Whitespaces for readability  Assign filenames to documents that describe their functionality.  This practice can help you identify documents faster  It also helps people who want to link to a page, by giving them an easy-to- remember name.  For example, if you are writing an HTML document that contains product information, you might want to call it products.html

6. HTML5 Tips for Good Programming  Indenting nested elements emphasizes a document’s structure and promotes readability.  Place comments throughout your markup.  Comments help other programmers understand the markup, assist in debugging and list useful information that you do not want the browser to render.  Comments also help you understand your own markup when you revisit a document to modify or update it in the future.  Remember comments in HTML always begin with. The browser ignores all text inside a comment

7. HTML5 Let’s Get Started: the Basic Tags  Open this free HTML editor: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_dd_test http://www.w3schools.com/tags/tryit.asp?filename=tryhtml_dd_test  Copy and paste the following code on the left column, then click on “See Result”:... this is the title on your website.... This is your first webpage... the body of your text goes here... Dr. Nazli Hardy

8. HTML5 The Basic Tags  You should see this:

9. HTML5 Basic HTML  In HTML, text is marked up with elements delimited by tags that are names contained in pairs of angle brackets  Every HTML document contains a start tag and an end tag  Comments in HTML always begin with. The browser ignores all text inside a comment  Every HTML document contains a head element which generally contains:  A head and a title element  A body element  head element  is not rendered in the display window  the title appears as the browser ‘tab’

10. HTML5 Practicing HTML  For the following sets of HTML code presented in the following slides, copy, paste onto the online HTML editor and see the result  Each slide builds on the next slide, so if you are having trouble with one slide, go back to the previous one  Once you start feeling confident, you can make some changes to the content within the tags  Like learning any new language, there is no alternative to trying out and practicing. I have taught several programming classes over the years, and this has been my tried and tested advise to my students. And also, try not to become frustrated. If you need a break, remove yourself from the computer, take a moment before starting again Partially adapted from Computer Security: Principles & Practices, Stallings, Lawrie

Follow the directions below (there are screenshots in the next slides) 1.Create a new folder. Call it EDW647 2.Open NotePad or TextEdit (do not use NotePad++ or Word or any other program because we need to use the simplest of programs) 3.Copy and paste the HTML code 4.Save the text files as YourName.txt (e.g. Nazli.txt) in your EDW647 folder 5.Then save the same text files again. This time as YourName.html (Note” the pull down menu should indicate “All Files”) 6.Open your EDW647 folder and click on the YourName.html document 7.You should be able to see your webpage 8.As long as you do not close either the NotePad/TextEdit or the browser window, you can make changes to your text document and simply reload the browser window to see the changes

32. HTML5 Additional Material  The following slides contain additional material for to try beyond this class. Millersville University Dr. Nazli Hardy

33. HTML5 Special Characters  XHTML provides special characters or entity references (in the form & code ; ) for representing characters that cannot be rendered otherwise  if x  What is the problem here?  if x &lt 10 then increment x by 1  This website is a good reference to the symbols: http://www.elizabethcastro.com/html/extras/entities.html http://www.elizabethcastro.com/html/extras/entities.html e.g. &copy &amp

34. HTML5 Special Characters Makes the 2 superscript Makes the 1 subscript Creates a strikethrough effect Emphasizes text Inserts the special symbols < and ¼ Partially adapted from adapted from “Internet & World Wide Web: How to Program”, Deitel & Deitel

35. HTML5 W3C XHTML Validation Service  Programming web-based applications can be complex, and XHTML documents must be written correctly to ensure that browsers process them properly  Most current browsers attempt to render XHTML documents even if they are invalid. This often leads to unexpected and possibly undesirable results.  Use a validation service, such as the W3C MarkUp Validation Service, to confirm that an XHTML document is syntactically correct.  World Wide Web Consortium (W3C) provides a validation service for checking a document’s syntax  http://validator.w3.org/
