Best Practices

(rev. Nov, 2009)

General

  1. Use XHTML Transitional 1.0 code as validated by the W3C. Do not use deprecated code.

    Justification: Current standard; HTML is being phased out in favor of XHTML.

    Supporting literature: http://validator.w3.org/docs/why.html, http://www.htmlhelp.com/design/standards.html, http://www.maxdesign.com.au/presentation/checklist.htm

    Exceptions: Use of the <embed>; tag JavaScript code or CSS IE hacks that might not validate.

    Helpful links: W3C’s validator: http://validator.w3.org/ Firefox Web Developer tool: https://addons.mozilla.org/firefox/60/

  2. Test and deem acceptable on all browsers supported by the University.

    Explanation and justification: While a good portion of our viewers (around 20% as of this writing) continue to use Internet Explorer 6, providing full support for this browser significantly infringes upon our ability to use the more advanced interactive features Internet users are expecting. Since there is no longer an institutional requirement to use IE 6, we request that users upgrade to IE 7 or later or switch to another supported browser such as Firefox or Safari.

    Exceptions: Mobile devices; Other exceptions can be made for intranet applications so long as they are clearly spelled out in the “technical requirements” section.

  3. Design for a minimum screen resolution of 1024x768.

    Justification: As of this writing, according to our latest usage statistics on the SOM web server, over 98% of our viewers use a screen resolution of 1024x768 or higher.

    Exceptions: Mobile devices, for which we define a separate style sheet, if needed.

    Helpful tools: Firefox Web Developer tool: https://addons.mozilla.org/firefox/60/ has an auto-resizing tool

  4. Use “@import” to link to external style sheets.

    Justification: Better consistency with very old browsers - will ignore the style sheet, altogether, rather than attempt to render styles.

    Supporting literature: http://www.yourhtmlsource.com/stylesheets/advancedcss.html, http://css-discuss.incutio.com/?page=ImportHack, http://www.w3.org/TR/REC-CSS2/media.html

    Exceptions: None.

  5. Avoid specifying font sizes for screen display in terms of points; leave unspecified or use another form of measure, instead; reserve points for the print style sheet.

    Justification: Accessibility; cross-browser compatibility; allowing the user to specify font size via his/her browser preferences.

    Supporting literature: http://webdesign.about.com/cs/typemeasurements/a/aa042803a.htm, http://developer.yahoo.com/yui/fonts/, http://www.clagnut.com/blog/348/

    Exceptions: None.

  6. Ensure that basic accessibility rules are met - e.g., use ALT tags for all images and provide alternative text for all images that contain textual information.

    Justification: Accessibility

    Supporting literature: http://www.w3.org/TR/WCAG10-HTML-TECHS/

    Exceptions: Sites where the audience is pre-selected to not include those with visual disabilities - e.g., the Admissions Status page or small-scale intranet applications whose user base is known and unlikely to change.

    Helpful Links: http://www.stopdesign.com/articles/replace_text/

  7. Ensure that all pages have a unique title. Use meta tags where appropriate.

    Justification: Aids in search engine indexing

    Supporting literature: http://www.w3.org/TR/WCAG10-HTML-TECHS/

    Exceptions: None.

  8. Avoid use of Flash, Ajax, or other similar technologies where it is superfluous and interferes with the user experience. Do not design Flash-only sites or Flash intro pages.

    Justification: Accessibility; printability; Flash content may be hidden to some users and to search engines; the inappropriate use of Flash (e.g., Flash intro pages) may delay the users' ability to get to the content they are looking for; browser features such as "Find in Page" and text translators will not work on Flash content; text is often not resizable in Flash.

    Supporting literature: http://www.sibagraphics.com/wp/category/web-design/resources/flash/

    Exceptions: Flash, Ajax, etc. may be appropriate for certain limited applications.

  9. Avoid use of frames and iframes.

    Justification: Accessibility; makes printing, bookmarking, and searching difficult.

    Supporting literature: http://www.yourhtmlsource.com/frames/goodorbad.html

    Exceptions: When there is no viable alternative to using an iframe.

    Helpful links: http://www.w3.org/TR/WCAG10-HTML-TECHS/#alt-frames

  10. Warn user of links to documents that require a plugin or external application (e.g., PDF, DOC, MOV) and provide file sizes if unusually large.

    Justification: Users may have slower connection speeds or lack the plugin needed.

    Exceptions: If an entire list of items is of the same document type, a warning at the top of the list is sufficient.

  11. Avoid using the <u> underline tag except for links.

    Justification: The <u> tag has been deprecated; underlining items which are not links is confusing to the user since the convention on the web is that only links are underlined.

    Supporting literature:http://webdesign.about.com/od/htmltags/p/bltags_u.htm

    Exceptions: None.

Best Practices for Contribute-enabled Sites

  1. Avoid using tables to place objects on the page; use CSS or CSS-P instead and reserve the use of tables for tabular data.

    Justification: Accessibility; separation of content and format; additional functionality available with CSS-P; XHTML code is less complicated than using tables; allows for more design control in Contribute.

    Supporting literature: http://www.w3.org/TR/WCAG10-HTML-TECHS, http://phrogz.net/CSS/WhyTablesAreBadForLayout.html, http://www.westciv.com/style_master, http://brainstormsandraves.com

    Exceptions: Laying out forms may prove easier to do using a table.

  2. Be selective in the use of JavaScript, Ajax, or Flash; be wary of ongoing maintenance issues.

    Justification: Content used within these technologies is not editable in Contribute, presenting a potential maintenance issue for SOMIS.

    Exceptions: Interactive content that requires this technology; small-scale intranet applications whose user base is known and unlikely to change; sites which already have an experienced Web Designer on staff or which plan to contract out for ongoing maintenance.

  3. Limit the use of custom styles in favor of predefined HTML tags.

    Justification: Use of custom styles requires that we explicitly allow access to those styles in Contribute (which we don’t normally do since this can be used improperly and requires more setup and user training).

    Exceptions: Sites not maintained via Contribute; styles applied outside of editable fields in the Dreamweaver template; custom styles that do not map to an existing HTML tag - in this case, these styles can be placed in a separate style sheet that the editor can access via Contribute.

Requirements for Site Handoffs from Outside Vendors

  1. Provide original images (PSD, EPS, etc.)
  2. Provide original documents used to produce PDFs, Flash Papers, etc.
  3. Provide a mapping of original images to corresponding web graphics.
  4. Provide a mapping of fonts used in each image.
  5. Provide all Dreamweaver templates.
