  1. HTML Introduction Creating a Web Page

  2. HTML: The Language of the Web • Web pages are text files, written in a language called Hypertext Markup Language or HTML. • A markup language is a language used to describe the contact and format of documents. • HTML was developed from the Standard Generalized Markup Language (SGML), a language used for large-scale documents. • SGML proved to be cumbersome and difficult, thus HTML was created.

  3. Tools for Creating HTML Documents • HTML documents are text files, which a text editor such as Windows NotePad can be used to create. • You can also use an HTML converter or an HTML editor. • an HTML converter like Microsoft Word takes text in one format and converts it to HTML code • an HTML editor helps you create an HTML file by inserting HTML codes for you as you work

  5. HTML Syntax • Document content is what the users sees on the page, such as headings and images. • Tags are the HTML codes that control the appearance of the document content. • tag is the name of the HTML tag • attributes are properties of the tag • document content is actual content that appears in the Web page

  6. HTML Tags • Tags can be one-sided or two-sided. • two-sided tags contain an opening tag <b> that tells the browser to turn on a feature and apply it to the contact that follows, and a closing tag </b> that turns off the feature • one-sided tags are used to insert noncharacter data into the Web page, such as a graphic image or video clip <tag attribute> • Tags are not case sensitive. The current standard is to display all tags in lowercase letters.

  7. HTML Tag Format • 1. Tagscan always be identified by the Brackets < > that enclose the tag name • 2. Opening Tag< >tells the browser to turn on the feature • Tag Name – macro-like feature • Properties – additional information placed within brackets that control how the tag is used • 3. Closing Tag</ >tells the browser to turn off the feature <Tag Name Properties> Document Content </Tag Name> Example: <h1>Mr. Dube’s Chemistry Classes</h1>

After I create this page, I’ll save it as an example of HTML coding.” • Save-As First_Program.htm(typically you will save in your wwwpub folder) • Close file and exit Notepad • Open the Internet Explorer file

  10. Making Changes to Web Pages • Open your Internet Explorer file (First_Program.htm) • Select View • Select Source (opens Notepad) • Make the desired changes in Notepad • Save HTML changes in Notepad • View the changes by selecting Refresh on the Internet Explorer screen • Close Notepad and Internet Explorer Note: Always save Notepad DO NOT save the Internet Explorer pages
