Use Good Alt Tags
Alt tags for images help make a site more accessible. WordPress will use the file name of an image as the Alt tag, but this is likely not going to be good enough to pass an accessibility review. A good alt tag briefly describes the content of an image.
No Table Layouts
Layouts of rows and columns should be done with Bootstrap code, not HTML Tables. Besides being inaccessible, HTML tables will also break your pages in mobile views! Tables should only be used when the content in a cell is defined by what row and column it belongs to.
Avoid ‘Click Here’ Links
Avoid ‘Click Here’ and similar phrases for links. Instead, have the link text describe the link destination. In addition to being more accessible, it will help with your Google search rankings. For example, “For more information about our admissions process click here” could be better as “More information about our admissions process“.
Use headings to organize your page content. For example, this page uses Heading 2 (h2) and Heading 3 (h3) tags. “Quick Tips to Keep Your Pages Accessible” is a Heading 2, and “Use Headings” is a Heading 3. Besides bringing in a larger font and adding white space, these headings are great for accessibility. They allow impaired users to skip through the heading tags the same way you would visually scan a page for headlines. Heading 3 would be a subsection within an Heading 2 section. You can add headings to a by going to Format > Formats > Headings or by using the keyboard shortcut (Control + 2, Control + 3, etc. on Windows, Command + 2, Command + 3, etc. on Mac). Headings help your site to look great, be more accessible, and they will really help your search engine rankings.
Watch Color Contrast
Be careful with color contrast. You will be able to change the color of your page text or upload images with text. Remember that users may have forms of color blindness or low vision. In the Resources section below, there are ways to measure the contrast levels with some websites or apps. In general, don’t put red text on a green background, or yellow text on a white background. Make sure your text is clearly legible.
Be sure to have contact information clearly visible on the website (homepage, main navigation, or footer), providing the ability to request alternate versions of inaccessible material to viewers with disabilities.
