Page Layout

Wide page forces users to scroll horizontally

When sites are constructed to require horizontal scrolling in order to navigate or read content at a normal size of 100% using standard screen sizes, additional problems can arise for users with low vision or mobility impairments.

This is some text you have to horizontally scroll to read.

Colour and Contrast

Color alone is used to convey content

Typography

Inadequate line height used

Many people with cognitive disabilities have trouble tracking lines of text when a block of text is single spaced. Providing spacing between 1.5 to 2 allows them to start a new line more easily once they have finished the previous one.

All caps text found

Typing sentences or phrases IN ALL CAPITALS is rarely a good idea. It may make sense under some circumstances, but only rarely. Lengthy segments of capitalized content are more difficult to read. In some cases, a screen reader may interpret ALL CAPITAL text as being an acronym and may read it as letters rather than words. For example, a screen reader may read the uppercase text CONTACT US as "Contact U. S." because it interprets the uppercase "US" as being an acronym for "United States".

Blinking text and moving text (such as a marquee) can distract the reader's attention. This is especially relevant to people with attention deficits or cognitive disabilities. Neither is likely to cause a seizure, but they are likely to decrease the readability of the document as a whole and increase the time it takes for users to finish reading it.

Italics used on long sections of text

Italics are sometimes used to highlight text. But you shouldn't use italicized text because they make letters hard to read. The letters have a jagged line compared to non-italic fonts. The letters also lean over making it hard for dyslexic users to make out the words. When the text size is small, the text is even more illegible.

Marquee element found

The BLINK and MARQUEE element animates content in a way that cannot be overridden or disabled by the user.

Long lines of text

For people with some reading or vision disabilities, long lines of text can become a significant barrier. They have trouble keeping their place and following the flow of text. Having a narrow block of text makes it easier for them to continue on to the next line in a block. Lines should not exceed 80 characters

Very small text found

This is some tiny text, much too small for some people to read

Justified text found

When text is justified to both margins it may add additional spaces between words which may be difficult for users with visual or cognitive impairments to read. Full text justification can also cause words to be spaced closely together thus making it difficult to determine where a word starts and ends.

Missing H1

Text formatting used instead of an actual heading

Fake Heading

This paragraph is preceded by a div that is styled to look like a heading

Headings not structured in a hierarchical manner

Heading 3

Pages should be structured in a hierarchical manner, generally with one 1st degree headings (h1) being the most important (usually page titles or main content heading), then 2nd degree headings (h2 - usually major section headings), down to 3rd degree headings (sub-sections of the h2), and so on.

Heading 5

Technically, lower degree headings should be contained within headings of the next highest degree (i.e., one should not skip heading levels, such as from an h2 to an h4, going down the document).

Heading 4

This is an example where heading levels have been skipped and are not in a logical order, which makes the page difficult to understand and navigate for people using assitive technologies such as screen reader.

    Lions are the only truly social cats, with related females living together in prides overseen by male coalitio that compete for possession in fierce and often fatal battles. Lions are predatory carnivores and it's the females that perform most of the hunting at night; the majority of the prey being antelope, zebra and wildebeest.
