Why and where to insert Alt Text in your Web Based Content.

Alt Text

Alt Text (or "Alternative Text") and captions provide a description of visual media (e.g. images, video) so the person can understand what the content in the media is

Alt Text In Canvas

Canvas provides a place to include alt text, but you will need to enter it manually.

Default Alt Text (name of the image) Canvas automatically populates the "Alt text" field for an image with the name of the file as the alternative text, but this is not the correct practice for providing alt text for an image.

For instance, the file name of the image below is kids-tech-revised.jpg, which Canvas automatically enters in the Alt text field.

Video Captioning

Make sure that the video you link to or create includes captions or a transcript of the audio to assist screen readers.

To check if the YouTube video includes captioning, check the lower right-hand side of the screen for the CC icon.

NOTE: Make sure you check the accuracy of the captions on YouTube before you upload it to your site. YouTube includes automated captioning which can often be inaccurate in comparison to the actual audio.
