2026 COMPREHENSIVE QUESTIONS AND
SOLUTIONS GRADED A+
◉ Page <title> rules: Answer: Page <title> must be present and must
contain text. Must be updated when the web address changes. Must
be accurate and informative. If a page is the result of a user action or
scripted change of context, the text of the <title> SHOULD describe
the result or change of context to the user. Should be concise. Should
be unique if possible. Unique information should come first. The
page <title> SHOULD match (or be very similar to) the top heading
in the main content.
◉ The primary language of the page MUST be identified accurately
on the <html> element. Answer: If the language is not specified, or if
it the language designation is inaccurate, a screen reader will read
the document in the user's default language, which may result in a
very bad accent if the page language doesn't match the user's
default. Or not understandable.
◉ The primary language of the page MUST be identified with a valid
value on the <html> element. Answer: Using 2 letter language code
or LCID string.
,◉ Inline language changes MUST be identified with a valid lang
attribute. Answer: Identify any changes of language within the
document. The lang attribute can be applied to block level elements
(<div>, <h1>, <p>, <table>, etc.) as well as inline elements (<span>,
<a>, <strong>, etc.).
Example:
<p>While in Spain, my friend tried to speak Spanish,
but she wasn't very good. Everyone kept saying
"<span lang="es">No comprendo nada de lo que
dices.</span>"</p>
◉ Landmarks SHOULD be used to designate pre-defined parts of the
layout (<header>, <nav>, <main>, <footer>, etc.). Answer: Use either
HTML 5 landmarks or their ARIA equivalents to mark sections of the
layout in the design, so that screen reader users can easily find their
way around the layout.
Landmarks are used to designate sections of the overall page design
and layout. Headings are used to designate sections within the
content.
◉ All text SHOULD be contained within a landmark region. Answer:
Labels for headers, mains, sections, articles, asides, footers, etc.
Using just <div> isn't enough.
, ◉ Multiple instances of the same type of landmark SHOULD be
distinguishable by different discernible labels (aria-label or aria-
labelledby). Answer: Example: <nav aria-label="Corporate and legal
info">
◉ A page SHOULD NOT contain more than one instance of each of
the following landmarks: banner, main, and contentinfo. Answer:
The ARIA specification states that the landmarks role="banner",
role="main", and role="contentinfo" are meant to be used only once
per page. Other ARIA landmarks can be used multiple times.
Interestingly, the HMTL 5 specification allows multiple instances of
the equivalent landmarks: <header>, <main>, and <footer>. The
official restriction is only on ARIA landmarks. Even so, it is
appropriate in most web designs to have only one each of these
landmarks, whether they are specified using ARIA or HTML 5.
◉ The total number of landmarks SHOULD be minimized to the
extent appropriate for the content. Answer: One of the main
purposes of landmarks is to allow blind users to quickly find and
navigate to the appropriate landmark, so you should keep the total
number of landmarks relatively low. If you don't, screen reader users
will have to sort through too much extra information to find what
they're looking for.
◉ Landmarks SHOULD be made backward compatible. Answer:
