Eco web design and accessibility

The website has been designed by EQUATION DURABLE to meet digital sustainibility and accessibility standards.

Website eco-design is an innovative and responsible approach to creating websites while preserving our environment.

We recognise the importance of making technology accessible to all users, whatever their abilities. We are committed to ensuring that our website is a platform that everyone can access and use seamlessly.

To achieve this goal, our website has been specifically designed to adhere to the European Union's Web Accessibility Directive guidelines.

Our commitment to accessibility is reflected in a number of specific improvements we have implemented:

  • Descriptive alt markup for non-aesthetic images, allowing screen readers to convey the content and purpose of images to users who cannot see them
  • Semantic HTML markup
  • ARIA notations to accurately describe content elements such as navigation elements, forms and tabular data
  • Focus indicators and ARIA tags
  • « Skip to content » functionality on each page to simplify navigation
  • Colour contrast
  • Support for motor skills
  • Zoom-friendly design. Our website remains fully functional and content-rich when resized up to 200%, meeting the needs of users who zoom in.
  • Minimal animations. Animations are used sparingly and respect browser controls to allow users to disable them, avoiding unnecessary distractions. In addition, as part of our commitment to sustainable development, we have eco-designed our site to reduce our carbon footprint. We have minimised the use of images and opted for vector graphics throughout the site to reduce file sizes and page load times.

By combining the principles of accessibility and sustainability, we aim to provide an inclusive and sustainable online experience for all visitors to EQUATION DURABLE.

The information provided by the Website operator is for information purposes only and does not exempt the User from carrying out an additional, personalised analysis.

The User must not use the Site or its content for any purpose that is unlawful or prohibited by these Terms of Use, or with a view to encouraging any illegal activity or any other activity that infringes the rights of EQUATION DURABLE or third parties.

Technical information

EQUATION DURABLE cannot be held responsible for elements beyond its control or for any damage to the User's technical environment, and in particular their computers, software, network equipment and any other material used to use the Site and/or the information contained therein.

Transmissions via the Internet network are never totally confidential or secure and it is the responsibility of each User to take all appropriate measures to protect their own data and/or software from contamination by any viruses circulating on the Internet.

EQUATION DURABLE endeavours to keep this Site up to date. Nevertheless, EQUATION DURABLE cannot guarantee the accuracy or completeness of any information made available.

Consequently, and within the limits authorised by applicable law, EQUATION DURABLE declines all responsibility for any indirect damage, whatever the cause, origin, nature or consequences, which may arise from a visit to the Site or associated with it, in particular and without limitation, any loss of profits, interruption of activities, loss of software or data.

Hypertext links

The creation of hypertext links to the Site is subject to the prior and express agreement of EQUATION DURABLE.

The Site may contain hypertext links to other websites. The existence of a hypertext link between the Site and a third party site does not in any way mean that EQUATION DURABLE guarantees the content of this Site or the use that may be made of it, and shall not in any way incur its liability. The User visits other sites at his own risk and under his own responsibility.

EQUATION DURABLE may not be held liable for access by Users to hypertext links set up within the framework of the Website leading to other resources present on the Internet network.
Users are reminded that delays, omissions or inaccuracies may occur due to the electronic transmission system.

Copyright - Intellectual property

All elements of the Site, taken individually or as a whole, are subject to the applicable legislation on intellectual property, copyright and trademark law, both in terms of form (tree structure, data layout, design, user-friendliness, etc.) and content (trademarks, texts, images, illustrations, music, sounds, etc.).

These elements are the exclusive property of EQUATION DURABLE or are licensed to it and EQUATION DURABLE is the sole authorised user.
Elements relating to our partners have been the subject of prior agreement and are subject to the same conditions of respect for copyright and intellectual property as for all other elements of the Site.

Any reproduction, representation or distribution, in whole or in part, of the pages, data and any other element of the Site, by any process or medium whatsoever, as well as any alteration thereof, is prohibited, except with the prior written authorisation of EQUATION DURABLE and would constitute an infringement punishable by articles L.335-2 et seq. of the French Intellectual Property Code.

The same applies to any databases appearing on the Web Site, which are protected by the provisions of the Law of 1 July 1998 transposing the European Directive of 11 March 1996 on the legal protection of databases into the Intellectual Property Code.

The trademarks of EQUATION DURABLE and its partners, as well as the logos appearing on the Site are semi-figurative or not and are registered. Any total or partial reproduction of these trademarks or logos made from elements of the Site without the express authorisation of the Website operator is therefore prohibited, within the meaning of article L.713-2 of the French Intellectual Property Code.

Users are informed that EQUATION DURABLE is not responsible for relations that may be established between a partner and an end customer.
