Terra Joule Journal: Accessibility Statement

Digital Commons is committed to web accessibility for all, regardless of ability or disability. We work continually to improve the accessibility and usability of Digital Commons, informed by web accessibility standards. Accessibility is an ideal and responsibility that we share with our scholarly community. We collaborate with the administrators at Terra Joule Journal to make this website and its contents as accessible as possible.

Standards Conformance

Digital Commons endeavors to meet all guidelines and standards established by the World Wide Web Consortium's Web Content Accessibility Guidelines (WCAG) 2.1 at level AA conformance, and Section 508 of the Federal Rehabilitation Act. These guidelines define how to make web content more accessible to people with disabilities, and conformance to them improves the web's usability for all people.

Digital Commons is partially compliant with WCAG 2.1 at level AA, and we make continual improvements with the aim of achieving full compliance. In certain areas, Digital Commons implements level AAA success criteria.

For a detailed review of how Digital Commons conforms with WCAG 2.1 success criteria, please refer to our Voluntary Product Accessibility Template (VPAT) document. This document was produced by the members of the Elsevier and Digital Commons internal accessibility teams.

Accessibility Features

Portable Document Format (PDF) Files

Digital Commons records may include PDF files as downloadable primary full texts or supplementary content.

Terra Joule Journal may choose to make tagged PDFs available for users of assistive technology. Document processing within Digital Commons preserves the tag structure of uploaded PDF files. Primary files may have a standard Digital Commons cover page (which contains appropriate tags) prepended to the document.

Terra Joule Journal may choose to make PDFs with searchable text or Optical Character Recognition (OCR) available.

Structural Markup

Main navigation links are consistent across pages in Terra Joule Journal. Site structure is standardized, as all pages comprise 4 sections:

  1. A header bar that includes the main navigation
  2. A main content area
  3. A sidebar
  4. A footer

When Cascading Styles Sheets (CSS) are disabled, or when using assistive technology, the 4 sections are read in the above order.

Most content and features are operable using only the keyboard. Most of the content of static pages can be accessed with JavaScript disabled in the web browser.

Skip Navigation Link

Keyboard users may bypass repetitive elements at the top of each page by immediately tabbing to the first interactive item, which is a “Skip to Main Content” link. This allows users to jump to the main section of the current page context.

Visual Design and Mobile Display

All pages and content may be enlarged using standard browser controls or screen magnification software.

A mobile-specific style sheet, with a smaller viewport, is applied for users loading pages on mobile devices. Pages are mostly usable when style sheets are disabled.

Text has sufficient contrast (4.5:1 for small text; 3:1 for large text) with its corresponding background to be clearly legible in almost all areas of the site. Links are visually distinguished from text, and most interactive elements also have obvious visual hover and focus states.

Access Keys

Access keys allow users to jump to specific elements of a web page using keyboard shortcuts. To activate an access key, press the modifier key + the access key.
