Example: cellpadding=“10” • Empty elements such as <img> must take this form <img/> • Non empty elements must have closing tags. Example: <p> content </p>

  7. Issues With Using XHTML • Inconsistency with layout of web pages • Navigation inconsistency • Bugs in the code. When linking, the links may go to the wrong webpage or site or may go nowhere. This is frustrating to users • Colors may not fit content of website or audience • Not all browsers support XHTML

  8. Things To Consider When Using XHTML • Content of web pages. What designers are trying to tell users about their site • Structure of website. How to link web pages properly for clear navigation (Farkas, 2002, pp.51-52) • Appearance of web pages. What web pages will look like to users • Think about the audience. How do they want the web site to look like? • Consider user’s needs. Think like the user

Examples of GUI components: textfields, textarea, labels, option buttons, command buttons, checkboxes, drop down list boxes • XHTML only places command buttons on the form. Does not allow command button action • CGI scripts only allow for command button actions, no other GUI component actions
