NPG Accessibility Statement

Starting from October 2004, Nature Publishing Group (NPG) sites are being constructed to be accessible to a wider range of people than before, including those using assistive technology.

Below is a list of some of the features we have adopted in order to make your browsing experience easier. Please do not hesitate to contact us if you have any problems accessing our content. We have tried to cater for as many people as possible but there may be occasions when we can further improve our accessibility.

Changing the font size

Accessible NPG websites now allow you to customize the font size to suit your personal preferences. Most browsers will allow you to change the font size. Below is a screenshot of Internet Explorer's "text size" menu option - most browsers have a similar feature - usually somewhere in the "View" menu. Please see the "help" section in your browser for more details on customisation.

"Liquid" page layout

Our user friendly "liquid" page layout ensures that our websites stretch to fill the space available to them, meaning that no matter what your browser window size or screen resolution, the website adapts itself to the space available. This means there is less horizontal scrolling at small resolutions, and should make the site easier to browse with a screen magnifier.

Top

We've positioned jump links at the top of the page so that you can quickly navigate to the most important sections of the page. This should be of use if you use a screen magnifier or speech browser, or are using a small screen resolution.

Top

Alternative content

For those members of our audience who use screenreader or speech browser software, we've provided sensible alternative text for images where this alternative text will aid your understanding of the webpage. If you discover an image that does not have suitable alternative text, please contact us.

Logical tab order and page layout

We've built pages so that it's easier to tab through the links - the content area is reached immediately after the header, making it easier to move around within a site. The jump links at the top of the page still provide fast and easy access to the main areas of every page, including the navigation.

Top

Headers

Our pages use structured headers to aid legibility. The first header on the page is the main content header followed by any appropriate sub-headers, then by headers for the navigation areas of the site.

This aids users of certain screenreaders and speech browsers - for instance: JAWS users can type INSERT+F6 to hear all the headers on the page, or CTRL+INSERT+ENTER to quickly navigate through the page by skipping to the next header.

Top

Tables

We are no longer using tables, except for the display of tabular data. For users of screenreaders and speech browsers, we associate headers with their respective rows and columns to aid legibility.

Top

Forms

Forms now have their labels explicitly associated with their controls, aiding users of certain screenreaders and speech browsers.

Customizing our sites

Due to the way we are building our sites, standards compliant browser users are able to heavily customize their individual look and feel. Each of our accessible sites has a unique class on the html "body" tag, meaning you can specify your own styles for each site.
