Time for your first hands on! Goal: Observe a simple text file. Activity: Create a .txt file, save it with the .htm or .html

extension and open it with a web browser.

1. Open Notepad (Start Program Accessory…) 2. Now close the dialog box, go to File, Edit with Notepad and

continue editing 3. In the file write your name and postal address in the same

way you would do on an envelope. 4. In File Name save as “Myaddress.html” in any folder you

like 5. Go to the folder where you saved your file and double click

on the icon of your file. It will be open with your default browser. What do you see?

6. Go back to your file and change the address with the school address. Save (CTRL S)

7. Do you see any change in the page? Reload the page. Do you see the changes now?

Web Page Creation

Create a document by using a mark-up language HTML or XHTML

Web Browsers show ASCII text

files, i.e. *.txt = text file *.html or *.htm = HTML files

Software is available to facilitate the Web page creation.

Web Browser

Web browser display Web pages make any effort to display on the best

way for laptop with smaller screen text is

rearranged formatting from text files is not preserved

(e.g. break lines are gone!).

Web browsers dynamically rework the files to fill the display window as best as it can

Web browsers rework each page for each visitor

What do I need to start? Do I need to be online while creating

my page? No, you can be offline You need to be online only when you

publish the page

Which Software do I need? A text editor

NotePad or A Friendly Web Editor is available in old

browsers like Netscape and SeaMonkey or Dreamweaver or Any other web editor, i.e.

FrontPage (not supported anymore) SeaMonkey, (the successor of Netscape) etc.

Page 8: Web Page Creation Part I - Kent State Universitypersonal.kent.edu/~aguercio/CS27101Slides/WID_Lect03_HTML_I.pdf · Web Browser Web browser display Web pages make any effort to display

Web Page: Basic Since Web browsers read text

files we can get a text file and display it the Web browser.

A Web server is not needed during page design you can be offline It is needed only at publication

time

HTML

HTML HyperText Markup Language is a language

that gives the author control over the web browser

set of HTML elements or tags insert a HTML element to add to a content or

a style to a Web page

Editing HTML files

Use Notepad (Windows) or SimpleText (Mac) for now. do not use Word

Word file saved as HTML invoke a HTML Converter which is not what you want when you are writing HTML files!

or save it “Text Only with Line Breaks”

If you prefer a more friendly web

editor, use Dreamweaver, Frontpage, Netscape Composer, SeaMonkey Composer, ect.
