Below are some Kentico specific instructions for publishers and editors at UW Bothell on how to make your webpages more accessible.
Any image that denotes information requires an alternative description (alt tag) for non-visual devices. If an image is purely decorative and serves no content purpose it can have an empty alt tag.
When inserting an image in Kentico, note that the Image/Edit dialog provides a field for the alt tag.
The text should describe the image or contain the actual text if there is text in the image. Note that if you insert an image through the Quickly Insert Image option it will automatically put the file name into the alt text field. This should be removed and replaced with readable text.
When selecting heading levels, ensure that they are in outline order. This will help the semantic structure of your page and assist those using non-visual devices. For example, a Heading 4 should only be a child of a Heading 3, not a Heading 2. Typicallys pages only have one Heading 2, maximum two; if you need more you may want to consider creating a new subpage for the information.
Creating an accessible data table
For a data table to be accessible, column and row headings need to be clearly marked and a caption added if there is not already a clearly related content header. To do this in Kentico use the following steps:
Marking column and row headers
Click on the table tool. In the Table Properties dialog select the Headers drop down. There are three options to create headers in the first row, the first column or both. Select the option that fits your data best.
You will know that they are correctly marked as headers by the styling. For example, "Both" was selected so this table has both row headers (light gray background) and column headers (dark gray background.)

If there is not already a descriptive header that introduces the data table, add a caption. The caption will appear before the table.

The optional summary field is for any details that may provide additional context of the table to a user of a non-visual device.
