This guide covers some of the potential accessibility issues in guides, and how they can be fixed. If you have any accessibility questions not covered in this guide, please feel free to contact Brandon Cornell (firstname.lastname@example.org) for assistance.
Text (and images of text) need to have sufficient contrast between background color and text color. If you know the color codes (indicated by a pound sign followed by 3 or 6 characters, such as #FFF or #BF5700) you can use WebAIM to check the contrast. All color combinations must pass WCAG AA on normal sized text. The "lighten" and "darken" buttons are useful for finding similar colors that are accessible.
You can often find the code for colored text by clicking the "source code" button on the content edit screen for the box content in your guide. Another option is to take a screen shot and use this page to check the colors on the image.
Images must have alt text. Whenever possible, this text needs to convey the same information as the image. For example, an image of text should have alt text that includes all of the words in the image. If the image is being used as a link, the alt text should indicate the destination of that link.
In the LibGuides editor, you can double click on an image to bring up the "Image Properties" box and type your alt text into the "Alternative Text" box. If you are adding an image in the source code, alt text can be added as follows: <img alt="alt text goes here" src="yourimagepathhere.jpg" />
