Frequent web page accessibility issues:

  • Frames — oftentimes, developers use frames as a convenient means to separate data sets. Frames are usually a virtual roadblock for users with visual impairments due to incompatibility with screen reader technology.
  • Alt tags — Alt tags are used to describe images. If an image is used to provide a user with content then the tag needs to correctly identify the image. If an image is used as a design element then the tag needs to be coded as alt=””. This will allow screen readers to pass over an image without wasting a user’s time.
  • CSS/XHTML –Structured markup will ensure that when images and formatting are removed, the content of a site will still be accessible for all users.
    Skip navigation links — If navigational menus are duplicated on all pages of a website than a developer should always provide the user with a means to skip the duplicated menu. This will create a heightened usability factor for your user.
  • New windows — When a web site opens a new window, a user’s navigation ability can be severely decreased. The back button becomes useless and the ability to navigate to the previous page becomes impossible.

  1. As always, I learned a lot today in our CSSA technology class! No questions right now, but will find questions for you when I start working on my website.
