* Ensure you have pause on hover enabled.

Module on Drupal.org https://drupal.org/project/accessible_skip_links
Navigation
Main Content
Complementary
Banner
Another way to “Skip Around:” Landmarks
content area landmark markup
page header; logo, <header role = “banner”>
navigational links <nav role = “navigation”>
primary content of page <main role = “main”>
used for extra content -- i.e., sidebar <aside role = “complementary”>
collection of items presented in a form <form role = “form”>
footer content <footer role = “contentinfo”>
search bar <form role = “search”>
Accepted Landmark Roles
Choose This:contextually relevant links
3. Navigation, continued.
Read More...what?
Read This Postbetter because it gives context to type of content.
Continue Reading [Title]full understanding of what action will happen a"er clicking on the link.
Contextually Relevant Read More
$node->content['accessible_read_more'] = array( '#markup' => l(t('Read Full !type', array('!type' => $node_type->name)), 'node/' . $node->nid, array( 'attributes' => array( 'title' => $node->title,

Remember those days when we had to typethe “quick brown fox jumped over the log” in our typing classes? I wonder if kids are still doing that today. How are they learning to type? I’m curious. Are they learning to type before they can write? Read Full Blog.

W3C RecommendationsWrite the contextually relevant text (i.e, title) in the anchor.
Here’s an example:
<a href="#"><span>Washington stimulates economic growth </span>Read More</a>
Wrap it in a span which you hide with CSS.
Use display:none but to make the screen reader pick it up, force it outside of the displayed area:
a span { height: 1px; width: 1px; position: absolute; overflow: hidden;
Sighted users will just see the words “Read more”, while screenreaders will hear “Link: Washington stimulates economic growth. Read More”
nice menus
Module on Drupal.org: https://drupal.org/project/nice_menus
Choose This:video players & image uploads that support captions & alt-text
4. Media
image accessibility: supporting alt text
ensure that media uploads have alt text field.
media module on Drupal has this:https://drupal.org/project/media

image accessibility: authoring alt text
1. KISS. Keep It Simple.
2. Short. Think of it like a Tweet.
Torn-down house from a tornado
Forlorn children stare at the rubble that was once their
house in the wake of a tornado
