Alt text description

For accessibility compliance, each image must have a concise and meaningful alternative text description (aka, alt text) applied. Alt text should be descriptive and no more than 125 characters. If text is trapped within the image, the text should be conveyed in the alt text as well.

  4. In the pop-up window, select “OK”
  5. In the editing ribbon, select the “Save and Exit” icon

Clear Content Around Images

If you have aligned an image left and you have reached a point that you no longer want content to wrap around the image, you will need to apply the "Clear Left-Right (Text)" style.

This style is used to clear text beneath an image, so that any content following the image and its associated text will not wrap around the image. 

To use this style:

  1. Place cursor in the last line of text that needs to appear next to the image
  2. From the "Styles" dropdown menu, select "Clear Left-Right (Text)"

mike

This is text that should wrap around the image and does not contain the "Clear Left-Right" style.

This is the text that should not wrap around the image. The preceding paragraph needs to contain the "clear left-right" style for this line to start beneath the image.

mike

This is text that should wrap around the image and contains the "Clear Left-Right" style.

This is the text that should not wrap around the image. Since the "clear left-right" style is applied to the preceding paragraph, this text appears beneath the image associated with that paragraph.

Homepage Sliders

The images in your slider asset cannot be loaded from the images file in your web directory, you must upload them from your desktop. Once images are loaded in the asset, they can only be updated, replaced or deleted from the within the asset file. 

We recommend that the slider contain no fewer than two images and no more than four. If you use more than four images in a slider, it is unlikely users will see or interact with any slide beyond the 4th or 5th slide.

Do not embed text in the actual image. If you feel you need to embed text in the image, it should be very brief and it should be the text that is then placed into the “Caption” field.

When editing the slider asset, you need to make sure to include text in all three of the text fields. This is to ensure the slider is meets accessibility requirements.

  • Title = Text in Purple Box [Required] 
  • Description = Text in White Box [Optional]
  • Caption = Concise and meaningful description of the image (i.e., Mike IV sitting on a rock in his habitat) [Required; no display, this text is for screen reader users only)
  • Link = URL to a webpage [Required] 

To edit a homepage slider, follow “Edit an Image Gallery” steps.
