and people with physical disabilities. Therefore it MUST be ensured that if
focus can be moved to a component of the page using a keyboard interface,
then focus can be moved away from that component using only a keyboard
interface, and, if it is not possible the user is advised of the method for
moving focus away. (Ref. WCAG 2.1.2)

h. It MUST be ensured that the purpose of each link can be determined from
the link text alone or from the link text along with its programmatically
determined link context e.g. by using title attribute as a tooltip to clarify the
purpose of link. (Ref. WCAG 2.4.4)

i. When any component receives focus, it MUST not initiate a change of
context. Developers must use “activate” rather than “focus” as a trigger for
change of context. This ensures that functionality is predictable as visitors
navigate their way through a webpage. (Examples of changing context when a
component receives focus include forms being submitted automatically when
a component receives focus or new windows launched when a component
receives focus). (Ref. WCAG 3.2.1)

j. Entering data or selecting a form control must have predictable effects.
Changing the setting of any user interface component MUST not
automatically cause a change of context unless the user has been advised of
the behaviour before using the component. Unexpected changes of context
can be disorienting for users with visual disabilities or cognitive limitations.
(Ref. WCAG 3.2.2)

k. Metadata adds semantic information to pages and sites and provides contextual
information for people navigating the site, especially those with screen readers
who rely on things such as page titles, structured page headings and lists.
Metadata may also be used by some search engines. Indian Government
websites MUST provide metadata like, keywords, and description at least on
Homepage and all important entry pages.

l. Tables help in organising and presenting data on a webpage. However, many
designers in the past have been using tables to make the layout of Web
pages. This has resulted in the Web pages not being accessible to people using
assistive technologies such as screen readers. For this reason, Use of Tables
for page layout should be avoided. For data tables, proper tags and markup
MUST be provided to identify row and column headers and associate data
cells and header cells.

m. When users navigate sequentially through content, they should encounter
information in an order that is consistent with the meaning of the content
