Curriculum for Addiction Professionals > Accessibility
Accessibility
SAMHSA is committed to ensuring that this course is accessible to everyone. If you
have any questions or suggestions regarding the accessibility of this course, please
contact us.
This page provides detailed information on this course's accessibility design. Many
features make this course more accessible, including:
- Fully functional pages, even with javascript turned off
- Relative font sizes for all text so text can be enlarged or reduced using the text
size options available in visual browsers (see
instructions below)
- Flexible page formats for all pages so pages can be automatically resized for different
window sizes and screen resolutions
- Pages designed with separate (external) style sheets, so they can be replaced by
user-defined style sheets
- A design using accessibility guidelines that follow federally mandated Section 508
and Web standards developed by the
World Wide Web Consortium's (W3C)
Web Accessibility Initiative (WAI)
.
Text Alternatives to Graphics
All navigation elements have text alternatives (alt text). We provide alt text for
all graphics in our code that convey content and empty or null alt text for graphics
in our code that do not convey content. Text alternatives are also provided using
the longdesc and d link attributes for visitors using screen readers.
In most screen readers, the defaul setting is set to skip over images that do not
have alt text, unless they are links, in which case screen readers read the link
destination.
Accessibility of Links and Screen Readers
Visitors using screen readers may navigate all links in the course by using the
keyboard. Screen readers allow users to skim Web content by tabbing from link to
link. The Tab key, in most browsers, allows you to jump from link to link
and the Enter key allows you to select a link. Most screen readers say
"link" at the beginning of each linked word or phrase. Some screen readers also
allow users to get an alphabetical list of links on a Web page. In JAWS, INSERT+F7
will activate the links list feature. Within the Links List window in JAWS, users
may move quickly through the list with the up and down arrow keys or they may jump
to a link by typing the first letter of a link name.

Change or Enlarge the Font Size
You may use your browser to increase the size of the text on the screen. Methods
for doing so differ from one browser to the next. The table below outlines the methods
used by some popular browsers. If your browser does not appear in the table, you
should find an option called "Text Zoom" or "Text Magnification"
or "Text Size" or "Font Size" under the "View" selection
on the main menu of your browser. From that point you should be able to find and
select an additional submenu option that adjusts the text size to your needs.

JAWS and Style Sheets
JAWS now allows you to control how it handles style sheets on Web pages. If you
experience difficulty reading Web pages or filling out forms in Internet Explorer
while using JAWS, press INSERT+V to change this option temporarily or INSERT+SHIFT+V
to change it for all pages within the current Web site domain. Select the option
"Style Sheet Processing" and press the SPACEBAR to select one of the following settings:
- Imported Style Sheets: Processes all style sheet information for
the page. This is the default setting.
- Top Level Style Sheets: Processes style sheet information embedded
in the page or linked externally. Choose this setting if you experience problems
with a Web page or if your browswer stops responding.
- Ignore Style Sheets: Suppresses all formatting and layout information
provided by the page's style sheet. This setting can help you work with difficult
forms or pages that JAWS cannot seem to read.
