ExxonMobil endeavours to ensure access to information for all users, including our employees and members of the public with disabilities.
ExxonMobil endeavours to ensure our sites meet the requirements of the Disability Discrimination Act 1995 and every effort is made to promote equality of opportunity for disabled people.
We have reviewed our sites based on the W3C's Web Content Accessibility Guidelines (WCAG), which are intended to help Web developers create content that is accessible to all visitors, identifying accessibility “checkpoints” by priority levels or A, AA, or AAA.
We aim to follow the World Wide Web Consortium’s (W3C) recommendations for accessibility and incorporate them into our template-based system. We use a variety of accessibility tools including screen readers and simulators for colour blindness. Based on our findings, we've documented guidelines for reference by our businesses and affiliates in the UK. Although we strive to deliver usable Web sites, some of our legacy sites or packaged sites by third-parties do not reflect our initiatives. For this reason, we work with third-parties to help us identify ways to continually improve our sites' accessibility.
At ExxonMobil, we endeavour to make our sites accessible and easy to use for all users. Our accessibility priorities are as follows:
- Provide text equivalents for non-text elements;
- Ensure that scripts allow accessibility;
- Allow documents to be readable without requiring an associated style sheet;
- Provide clear and consistent navigation;
- Convey information with colour as effectively as without colour;
- Enable users to skip repetitive navigation links; and
- Ensure that plug-ins and applets meet the requirements for accessibility.
Ease of Use
We strive to ensure that all pages are valid to Extensible Hyper Text Mark-up Language (XHTML) 1.0 Transitional and use valid Cascading Style Sheets (CSS).
Our layout takes into account users who are visually impaired or have difficulties using a mouse. They are compatible with popular screen reading software and can be navigated using only a keyboard.
Headings and navigation menus
HTML heading tags are used to convey document structure. H1 tags are used for main titles, H2 tags for subtitles etc.
We prioritise the use of descriptive alt tag attributes for images. Where an image has no use other than being decorative the alt tag is set to null to allow easy reading by all users.
We have taken care to ensure that font and background colour combinations contrast significantly and are effective in ensuring information is still clear when viewed in different colour combinations.
Most of the font sizes we use are sizable. You can change the font size to make it either larger or smaller via your browser settings.
You can change the font size in the following ways depending on your browser:
- In Internet Explorer; select View, then Text Size, and then your preferred size.
- In Firefox; select View, then Text Zoom, and then your preferred percentage size.
We use cascading style sheets (CSS) for all visual layouts. If your browser or browsing device does not support style sheets, the use of structured semantic mark up ensures that the content of each page is still readable and clearly structured.
Forms and fields
Forms fields are designed to follow a logical tab sequence to ensure easy navigation.
Most form fields also have ‘label’ and ‘id’ attributes to help associate the form field with its label to allow for easy entry of data.
Most links have been written to make sense when taken out of context. Where appropriate, we have also added link title attributes to describe the link in greater detail.
