Our aim is to ensure that DNSA is accessible to everyone. Please contact us if you have any questions or suggestions about the accessibility of this site.
You will find information below on how to navigate DNSA, what you can do to view the site in a more accessible way, and any features which may have implications for accessibility. You will also find a brief statement of our policy towards complying with accessibility standards for the Web.
Sitewide Navigation Features
At the top of every page in DNSA there is a list of links to the main functional areas of the site and context-sensitive Help, which opens in a new window. You can use the Quick Search box, located at the top of every page, to quickly search all of the content in DNSA.
In addition, navigation options relevant to a particular page appear at the start of the content area, e.g. the Modify Search link on the List of Results page.
If you use a screen reader or keyboard to access DNSA you can bypass the sitewide navigation links using the “skip over navigation” link at the top of each page or the relevant access key (see Using Access Keys section below). This link is usually hidden from view but can be displayed on screen using the TAB key.
The Site Map provides a list of links to all the main areas and sub-areas of the site. To open the Site Map from any page click on the link in the bottom navigation bar (access key z), then follow the link for the page you wish to open.

Pop-ups in DNSA
This site makes use of pop-ups to provide some types of content. For example, the help opens in a pop-up so you can easily switch between reading the help and looking at the site. Pop-ups are not used for advertising on this site, they only include site content.
If you have a browser pop-up blocker activated you will need to disable it for full access to the content in DNSA. Alternatively, most pop-up blockers can be configured to allow pop-ups for sites you select whilst still blocking pop-ups from other sites. Please refer to your browser help for details on how to disable your pop-up blocker or allow pop-ups for this site.
