  1. Modern Web standards in SEMIDE portals • Miruna Bădescu • Finsiel Romania Sophia Antipolis, September 2006

  2. Web Accessibility • The site information must be accessible to: • all users, including users with physical, mental or technical disabilities • all types of devices (different browsers, PDAs and mobile phones, TVs, speech synthesizers, Braille interpreters, TVs, printers, etc.) • other web sites, web applications and search engines • WAI (Web Accessibility Initiative) – guidelines discussing accessibility issues and providing accessible design solutions • There are three levels of conformance: • WAI A Conformance Level "A“ (used in CHM for administration functionalities) • WAI AA Conformance Level "Double-A" (used in CHM for end users interface) • WAI AAA Conformance Level "Triple-A“; the most strict

  4. Usability • Ensuring a “Easy to use” (or “User friendly”) interface supposes to: • improve the website navigation(ex: search, sitemap) • improve the user orientation within the site (ex: bread crumb trail) • improve user control and flexibility(ex: language option)

  6. Semantic HTML • “Semantic Web” refers to Machine-Understandable information • Semantically correct HTML is important - thinking on how applications (Google for instance) interpret it, more than how users view it • Use the proper HTML tags for certain types of information • use of <h1>,<h2> tags for headings, use of <table> only for tabular information and NOT for the layout design... etc.

  8. XHTML (eXtensible Hyper Text Markup Language) • XHTML is a family of document types that reproduce and extend HTML4 and are XML-based • XHTML documents are XML conforming (is designed to work with XML-based user agents and can be validated using XML tools) • Can utilize applications (e.g. scripts and applets) that rely on • either the HTML Document Object Model • or the XML Document Object Model

  9. XHTML - Further reading • http://www.w3.org/TR/xhtml1/ • Validation service • http://validator.w3.org/

  10. CSS2 • The Cascading Style Sheets (CSS) are used for the graphical presentation of website layouts. Target! Complete separation of the structure from presentation – the CSS should have absolute control over the appearance. CSS level 2 • is used in two major directions: for the elements positioning and for their stylization • builds on CSS1 and, with very few exceptions, all valid CSS1 style sheets are valid CSS2 style sheets • allows information to be presented differently according to the target media (screen, printer, handheld/mobile etc.) and to the client’s settings (alternative layouts, text browsers, etc.)
