World Wide Web • What is the WWW? • What are websites made up of? • Servers / Clients • HTML, scripts, etc. • What does your “Browser” do? • How can you develop web sites (pages)? • Ease of use versus functionality
HTML • Series of tags and objects • <tag>object</tag> • Tags • Define, describe and position web pages and objects on pages. • Typically come in a set of opening and closing tags – two sided • <h1>Welcome to Billy’s Web Page</h1> • Particular keyword that indicates the type of object. • <h2>xxx</h2> or <p>These pages are for…</p> • Tags may have attributes that further define and describe the appearance and position the object. • <p style=“text-align: justify”>These pages are for…</p> • May be one sided: • These tags do not need to be closed later in the page • <br /> <hr /> <img src=”sufflogo.jpg” /> • May be comment tags: • <!- - comment - -> • Terms: • Render: browser interprets html and builds GUI web page. • Deprecated: a tag set is discouraged and will not be supported in future browsers.
Creating a Web Page • <html> tag: • First line of a web page. • Closed with </html> tag – last line of a web page. • Two sections: • Head: <head> </head> • Contains information to identify and describe the web page. • Contents do not appear on the page. • <meta description=“…”> - provides terms to search engines • <title>….</title> - appears in browsers title bar • <! - - comments - -> - more fully describe page • <script>…</script> - scripting to make page more dynamic • Body: <body> </body> • Everything that will appear in the browser window. • Contains the content and formatting instructions for the objects on the page • <h1>x</h1> <p>x</p> <br /> <img src=“file.suffix” />
HTML Creation Rules • Build in Notepad or other text editor. • Use lower case for tags. • HTML files can be opened directly from your file storage area. • If you open it …close it. • Don’t put spaces into folder or files names. • Use outlining and space to keep document (html file) readable. • Let’s build a shell.
