  1. Introduction to HTMLLists, Images, and Links

  2. Before We Begin • Save another file in Notepad • Open your HTML, then do File>Save As • Make sure your saving in the same place • ‘Save As Type’ should be ‘All Files’ • In ‘File name’, use the same name but put ‘2’ at the end then ‘.html’ • Click the Save button • Remove everything between the <BODY> and </BODY> tags • Change the title appropriately

  3. Lists • Lists are used to group related pieces of info together • Makes it clear they are related • Makes it easier to read • Can be ordered (numbered) or unordered (bulleted)

  4. Unordered List • Creates a bulleted list • Uses one set of <UL></UL> tags enclosing one or more sets of <LI></LI> tags • Like this: <UL> <LI>Item1</LI> <LI>Item2</LI> </UL>

  5. Unordered List Example • Put this in the Body of your HTML: <h1>Some facts about lists</h1> <ul> <li>They group things</li> <li>Some have bullets </li> <li>Some have numbers</li> </ul> 1

  6. Ordered List • Creates a numbered list • Uses one set of <OL></OL> tags enclosing one or more sets of <LI></LI> tags • Like this: <OL> <LI>Item1</LI> <LI>Item2</LI> </OL>

  7. Ordered List • Can also use letters or roman numerals by using the ‘Type’ attribute on the <OL> tag • Like this <OL TYPE=?> • ?=a - lower case letters • ?=A - upper case letters • ?=i - lower case roman numerals • ?=I - upper case roman numerals

  8. Ordered List Example • Put this after the unordered list: <h1>Steps to add a list</h1> <ol> <li>Type the OL or UL tag</li> <li>Type the list items </li> <li>Type the correct end tag</li> </ol> • Next, try out the ‘type’ options 2

  9. Images • Used to make your web page more interesting (among other things) • Use caution when adding images • Download times • Not all people may be able to see them

  10. Images • Can be any graphic file • Pictures • Drawings • Buttons • Etc., etc. • Can be still or animated (moving) • Multiple types: jpg, gif, png, etc.

  11. Images • Using images requires the browser to find a file containing the image • You must provide the filename and possibly the file’s location (path) • If you don’t provide a location, the image file must be in the same folder as the HTML source file

  12. Images • Displayed using the IMG tag • The IMG tag uses the SRC (source) attribute to tell it the name (always) and location (if necessary) of the image file • Like this: <IMG SRC=“image1.jpg”>

  13. Images • IMG tag also uses the ALT (alternative) attribute to show text if the picture can’t display • Like this: <IMG SRC=“image1.jpg” ALT=“Picture of some idiot”> • IE will also show it as a tooltip

  14. Images • Other IMG attributes • HEIGHT=# (# is number of pixels or %) • WIDTH=# • ALIGN=? – controls images position in relation to the text around it • ? can be LEFT, RIGHT

  15. Images Example • First, find and save an image file • Go to the Web and find a picture • Right-click on it, then ‘Save Picture As’ • Change ‘Save In’ location to the same folder where your HTML file is • Change the filename to something short and sweet • Note what’s in ‘Save as type’ • Click ‘Save’

  16. Images Example • Put this after the ordered list: <h1>Image stuff</h1> <IMG SRC=“filename.filetype” ALT=“my picture”> I’m trying out images. This might be fun – well, sort of. • ‘filename’ is what you called it • ‘filetype’ is what was in ‘save as type’ when you saved it 3

  17. Images Example • Put this after the last image stuff: <h1>More Image stuff</h1> <IMG SRC=“filename.filetype” ALT=“my picture again” HEIGHT=# WIDTH=# ALIGN=???> Let’s see what happens when I use the attributes on the IMG tag. • Enter different values for # and ??? and see what happens

  18. Links • Main way web pages are connected • Called Anchor links • Uses the Anchor tag <A></A> • Whatever is between the two tags becomes the link on your page • You can link to virtually any file

  19. Links • The <A> tag uses the HREF attribute to point to the other page/file. • Like this: <A HREF=“URL or file”>Text that shows as the link</A>

  20. Links • As with images, links require the browser to find the page or file • For external web pages, you must provide the correct URL (it’s best to include the whole thing including http://) • For local pages and files, you must provide the filename and possibly the file’s location (path) • If you don’t provide a location, the page/file must be in the same folder as the HTML source file

  21. Links • External web page example <A HREF=“http://www.yahoo.com”> Yahoo</A> • Local web page example <A HREF=“somepage.html”>My Page</A> • Local file example <A HREF=“somefile.doc”>My doc</A>

  22. Links Example - External • Put this after the image stuff: <BR> <h1>External link</h1> <A HREF=“http://www.ajc.com”>Click here for the AJC</A> <BR>

  23. Links Example – Your Other Page • Put this after the external link: <BR> <h1>Link to my other page</h1> <A HREF=“{name of your first page}.html”>Click here for my first web page</A> <BR> 4

  24. Links Example – Your Other Page • Open your first HTML file and add this at the bottom: <BR> <h1>Link to my other page</h1> <A HREF=“{name of your second page}.html”>Click here for my second web page</A> <BR>

  25. Links • Want to create a popup? Use the TARGET=“_blank” attribute to open the linked page in another window <A HREF=“http://www.yahoo.com” TARGET=“_blank”> Yahoo</A> • Try it!!
