Accessibility StatementCompliance status
We firmly believe that the internet should be available and accessible to anyone
and are committed to providing a website that is accessible to the broadest
possible audience, regardless of ability.
To fulfill this, we aim to adhere as strictly as possible to the World Wide Web
Consortium’s (W3C) Web Content Accessibility Guidelines 2.1 (WCAG 2.1) at the AA
level. These guidelines explain how to make web content accessible to people
with a wide array of disabilities. Complying with those guidelines helps us
ensure that the website is accessible to blind people, people with motor
impairments, visual impairment, cognitive disabilities, and more.
This website utilizes various technologies that are meant to make it as
accessible as possible at all times. We utilize an accessibility interface that
allows persons with specific disabilities to adjust the website’s UI (user
interface) and design it to their personal needs.
Additionally, the website utilizes an AI-based application that runs in the
background and optimizes its accessibility level constantly. This application
remediates the website’s HTML, adapts its functionality and behavior for
screen-readers used by blind users, and for keyboard functions used by
individuals with motor impairments.
If you wish to contact the website’s owner please use the website's form
Screen-reader and keyboard navigation
Our website implements the ARIA attributes (Accessible Rich Internet
Applications) technique, alongside various behavioral changes, to ensure blind
users visiting with screen-readers can read, comprehend, and enjoy the website’s
functions. As soon as a user with a screen-reader enters your site, they
immediately receive a prompt to enter the Screen-Reader Profile so they can
browse and operate your site effectively. Here’s how our website covers some of
the most important screen-reader requirements:
1. Screen-reader optimization: we run a process that learns the website’s
components from top to bottom, to ensure ongoing compliance even when
updating the website. In this process, we provide screen-readers with
meaningful data using the ARIA set of attributes. For example, we provide
accurate form labels; descriptions for actionable icons (social media icons,
search icons, cart icons, etc.); validation guidance for form inputs;
element roles such as buttons, menus, modal dialogues (popups), and others.
Additionally, the background process scans all of the website’s images. It
provides an accurate and meaningful image-object-recognition-based
description as an ALT (alternate text) tag for images that are not
described. It will also extract texts embedded within the image using an OCR
(optical character recognition) technology. To turn on screen-reader
adjustments at any time, users need only to press the Alt+1 keyboard
combination. Screen-reader users also get automatic announcements to turn
the Screen-reader mode on as soon as they enter the website.
These adjustments are compatible with popular screen readers such as JAWS,
NVDA, VoiceOver, and TalkBack.
2. Keyboard navigation optimization: The background process also adjusts the
website’s HTML and adds various behaviors using JavaScript code to make the
website operable by the keyboard. This includes the ability to navigate the
website using the Tab and Shift+Tab keys, operate dropdowns with the arrow
keys, close them with Esc, trigger buttons and links using the Enter key,
navigate between radio and checkbox elements using the arrow keys, and fill
them in with the Spacebar or Enter key.
Additionally, keyboard users will find content-skip menus available at any
time by clicking Alt+2, or as the first element of the site while navigating
with the keyboard. The background process also handles triggered popups by
moving the keyboard focus towards them as soon as they appear, not allowing
the focus to drift outside.
Users can also use shortcuts such as “M” (menus), “H” (headings), “F”
(forms), “B” (buttons), and “G” (graphics) to jump to specific elements.
Disability profiles supported on our website
* Epilepsy Safe Profile: this profile enables people with epilepsy to safely
use the website by eliminating the risk of seizures resulting from flashing
or blinking animations and risky color combinations.
* Vision Impaired Profile: this profile adjusts the website so that it is
accessible to the majority of visual impairments such as Degrading Eyesight,
Tunnel Vision, Cataract, Glaucoma, and others.
* Cognitive Disability Profile: this profile provides various assistive
features to help users with cognitive disabilities such as Autism, Dyslexia,
CVA, and others, to focus on the essential elements more easily.
* ADHD Friendly Profile: this profile significantly reduces distractions and
noise to help people with ADHD, and Neurodevelopmental disorders browse,
read, and focus on the essential elements more easily.
* Blind Users Profile (Screen-readers): this profile adjusts the website to be
compatible with screen-readers such as JAWS, NVDA, VoiceOver, and TalkBack. A
screen-reader is installed on the blind user’s computer, and this site is
compatible with it.
* Keyboard Navigation Profile (Motor-Impaired): this profile enables
motor-impaired persons to operate the website using the keyboard Tab,
Shift+Tab, and the Enter keys. Users can also use shortcuts such as “M”
(menus), “H” (headings), “F” (forms), “B” (buttons), and “G” (graphics) to
jump to specific elements.
Additional UI, design, and readability adjustments
1. Font adjustments – users can increase and decrease its size, change its
family (type), adjust the spacing, alignment, line height, and more.

3. Animations – epileptic users can stop all running animations with the click
of a button. Animations controlled by the interface include videos, GIFs,
and CSS flashing transitions.
4. Content highlighting – users can choose to emphasize essential elements such
as links and titles. They can also choose to highlight focused or hovered
elements only.
5. Audio muting – users with hearing devices may experience headaches or other
issues due to automatic audio playing. This option lets users mute the
entire website instantly.
6. Cognitive disorders – we utilize a search engine linked to Wikipedia and
Wiktionary, allowing people with cognitive disorders to decipher meanings of
phrases, initials, slang, and others.
7. Additional functions – we allow users to change cursor color and size, use a
printing mode, enable a virtual keyboard, and many other functions.
Assistive technology and browser compatibility
We aim to support as many browsers and assistive technologies as possible, so
our users can choose the best fitting tools for them, with as few limitations as
possible. Therefore, we have worked very hard to be able to support all major
systems that comprise over 95% of the user market share, including Google
Chrome, Mozilla Firefox, Apple Safari, Opera and Microsoft Edge, JAWS, and NVDA
(screen readers), both for Windows and MAC users.
Notes, comments, and feedback
Despite our very best efforts to allow anybody to adjust the website to their
needs, there may still be pages or sections that are not fully accessible, are
in the process of becoming accessible, or are lacking an adequate technological
solution to make them accessible. Still, we are continually improving our
accessibility, adding, updating, improving its options and features, and
developing and adopting new technologies. All this is meant to reach the optimal
level of accessibility following technological advancements. If you wish to
