Behind the Scenes of a Web Page
Foundation on which design is built.• HyperText Markup Language (HTML)
Develop in text editor (i.e. NotePad), Word, web authoring tool, “cut-n-paste”.
• HTML Kit www.chami.com/html-kit/
• Many tools create “bad” or “junky” code.– i.e. Frontpage, “Save As Webpage”.
Elements create framework and structure content.
• All elements have a start tag <keyword> • Most, but not all elements have end tag
</keyword>

Define acronyms and abbreviations Helps text-to-speech technology, cognitive
disabilities plus different language and learning styles.
Consider providing a “glossary”.• i.e. www.catea.org/grade/legal/glossary.html
Spell out first instance in text.• Way Too Much Information (WTMI)
Use <acronym> and <abbr> tags.
<acronym title=“Also Known As”>AKA</acronym>
<abbr title=“Street”>St.</abbr>

Identify LanguageEnables proper reading by text-to-speech
and screenreader technology.
Use “lang” attribute:• Use with <html> tag to apply to whole document
<html lang=“en”>• Use with any tag to identify language changes
<p lang=“es”>Hola! Mi amigos!</p>
• Use with <span> tag to apply to an instance<p>Spanish for hello: <span
lang=“es”>Hola!</span></p>
