This was inspired by the main idea in <\/span><i><span style=\"font-weight: 400\">Atomic Habits<\/span><\/i><span style=\"font-weight: 400\"> by James Clear: changes that are very small but applied consistently can make a big difference over time.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">We have a lot of <a href=\"https:\/\/support.emerson.edu\/hc\/en-us\/sections\/360011681191-Accessibility\">resources on accessibility at Emerson<\/a>,<\/span><span style=\"font-weight: 400\">\u00a0and I encourage you to check them out. Our resources cover accessibility concerns for specific software, like Canvas and Panopto, but there are also principles that are applicable across the board. In this blog post, I\u2019ll be covering tips for images and visual content? What does \u201cvisual content styling\u201d mean, if not images? Read on to find out!\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Here are three tips for shifting how you work with images and visual content styling so that it\u2019s more accessibility-friendly from the start:\u00a0<\/span><\/p>\n<h2><span style=\"font-weight: 400\">Tip 1: Provide Alt Text for Images<\/span><\/h2>\n<p><span style=\"font-weight: 400\">Screen readers don\u2019t have the ability to describe an image on their own, so it\u2019s important to add alt text for any images that you use. Screen readers can read the alt text, and the alt text communicates the description and significance of images. A screen reader will just skip over an image that doesn\u2019t have alt text, and the screen reader user will not have a way of knowing what the image is or its significance.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">The image below is a screenshot of the image options interface in Canvas, which shows the alt text field. In this case, I added alt text to the image when I uploaded the image. And yes, this screenshot has alt text!\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-5315 size-large\" src=\"https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2024\/08\/Screenshot-2024-07-31-at-2.06.06-PM-1024x601.png\" alt=\"The Rich Content Editor in Canvas and Image Options where you can add alt text\" width=\"640\" height=\"376\" srcset=\"https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2024\/08\/Screenshot-2024-07-31-at-2.06.06-PM-1024x601.png 1024w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2024\/08\/Screenshot-2024-07-31-at-2.06.06-PM-300x176.png 300w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2024\/08\/Screenshot-2024-07-31-at-2.06.06-PM-768x451.png 768w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2024\/08\/Screenshot-2024-07-31-at-2.06.06-PM.png 1422w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/p>\n<p><span style=\"font-weight: 400\">The interface for adding alt text varies according to the application you are using, but this is such an important aspect of accessibility that there should always be a way to add alt text regardless of the application. Here are instructions on adding alt text in some commonly used applications at Emerson:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400\"><a href=\"https:\/\/support.emerson.edu\/hc\/en-us\/articles\/205015539-Creating-Accessible-Canvas-Content#how-to-add-alt-text-0-4\"><span style=\"font-weight: 400\">How to Add Alt Text in Canvas<\/span><\/a><\/li>\n<li style=\"font-weight: 400\"><a href=\"https:\/\/support.emerson.edu\/hc\/en-us\/articles\/360017461632-Creating-Accessible-Documents#include-alt-text-for-images-0-2\"><span style=\"font-weight: 400\">How to Add Alt Text in Word<\/span><\/a><\/li>\n<li style=\"font-weight: 400\"><a href=\"https:\/\/support.google.com\/docs\/answer\/6199477?hl=en\"><span style=\"font-weight: 400\">How to Add Alt Text in Google Docs<\/span><\/a><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400\">It\u2019s generally best practice to keep alt text to under 150 characters (1-2 sentences). Also, you don\u2019t need to start the alt text with \u201cimage of\u201d or &#8220;picture of.&#8221; The screen reader will take care of that!\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Consider the context of the image when writing the alt text. For example, say that you have a picture of a Monet painting framed and displayed on a wall in a museum. If the image is there because you wanted an image illustrating how art museums display paintings, then the alt text should mention that. If the fact that the painting is by Monet is significant, then the alt text should focus on that.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Still stumped on how to approach writing alt text?

Do you remember the section from my last blog post about why you need to use actual headers, not simply change the style to bold and a bigger font color? That\u2019s because things like the font styling and size aren\u2019t picked up by screen readers.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">To be clear, it\u2019s ok to use font styling and different font colors. (One caveat is that the font colors should have sufficient contrast &#8211; more on that in the next section!) But these styling options shouldn\u2019t be the only way that a piece of information is communicated.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">For example, let\u2019s say that you have a slideshow for a lecture, and you have a slide at the beginning that outlines the content for that lecture. There are one or two components of this lecture that you really want to emphasize as being important, so you change the font color of the text to red, or you change the font style to bold, or even both. For a sighted user, the difference in the visual styling is perceivable and it can be inferred that these are topics of special importance. However, a screen reader is not going to pick up on the styling differences, and the special emphasis you intend to place on those topics is not communicated. There\u2019s an easy way to fix this, though! You can add a preface such as \u201cImportant\u201d to those topics on the outline. Now the meaning of the font formatting is also conveyed through text.\u00a0<\/span><\/p>\n<p>Not conveying meaning through color alone is also important for people who have colorblindness. <a href=\"https:\/\/www.theverge.com\/23650428\/colorblindness-design-ui-accessibility-wordle\">Examples of what colors can look like with colorblindness<\/a> are very helpful for understanding what information can be lost when it&#8217;s conveyed only through color. I also recommend checking out this video: <a href=\"https:\/\/www.youtube.com\/watch?v=8_eVF0LPs0s\">Use of Color Alone to Convey Information<\/a>. It has an example of how to make a color-coded event calendar accessible.<\/p>\n<h2><span style=\"font-weight: 400\">Tip 3: Use Colors with Enough Contrast<\/span><\/h2>\n<p><span style=\"font-weight: 400\">On more than one occasion, I\u2019ve been in a situation where there were no more pens available (pens do tend to walk away) and needed to use a yellow highlighter to write something down. And I only had white paper. If it was a big yellow highlighter, then I had to write bigger, and I had a chance of actually being able to read what I\u2019d written down. But if all that was available was a small highlighter, I was pretty much out of luck.<\/span><\/p>\n<p><span style=\"font-weight: 400\">You may be wondering why on earth I\u2019ve brought up this anecdote, but I\u2019m using it to demonstrate two important things about color contrast. The first is that light colors on light backgrounds are very difficult to read. They\u2019re even harder to read if you have <\/span><a href=\"https:\/\/www.nei.nih.gov\/learn-about-eye-health\/eye-conditions-and-diseases\/low-vision\"><span style=\"font-weight: 400\">low vision<\/span><\/a><span style=\"font-weight: 400\">! The second is that a light color on a light background can be easier to read if the lettering is bigger. It still may not be an acceptable level of color contrast, but the font size does play a role in this. There are <\/span><a href=\"https:\/\/support.emerson.edu\/hc\/en-us\/articles\/360017461632-Creating-Accessible-Documents#colors-and-graphics-0-6\"><span style=\"font-weight: 400\">tools to help determine sufficient color contrast<\/span><\/a><span style=\"font-weight: 400\">. Black text on a white background is a safe choice and a classic for good reason!\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Here is an example of text in different colors and font sizes in Canvas and the <\/span><a href=\"https:\/\/community.canvaslms.com\/t5\/Instructor-Guide\/How-do-I-use-the-Accessibility-Checker-in-the-Rich-Content\/ta-p\/820\"><span style=\"font-weight: 400\">Canvas Accessibility Checker\u2019<\/span><\/a><span style=\"font-weight: 400\">s evaluation of them. To get technical, text smaller than 18pt or 14pt bold should have a minimum contrast ratio of 4:5:1.\u00a0\u00a0<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-4995 \" src=\"https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2023\/08\/Screen-Shot-2023-04-13-at-3.33.17-PM.png\" alt=\"An example of text in different colors and sizes illustrating contrast ratio, with yellow and red text not passing the accessibility checked, but dark purple and dark blue do pass\" width=\"865\" height=\"367\" srcset=\"https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2023\/08\/Screen-Shot-2023-04-13-at-3.33.17-PM.png 1530w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2023\/08\/Screen-Shot-2023-04-13-at-3.33.17-PM-300x127.png 300w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2023\/08\/Screen-Shot-2023-04-13-at-3.33.17-PM-1024x434.png 1024w, https:\/\/websites.emerson.edu\/itg\/wp-content\/uploads\/sites\/44\/2023\/08\/Screen-Shot-2023-04-13-at-3.33.17-PM-768x326.png 768w\" sizes=\"auto, (max-width: 865px) 100vw, 865px\" \/><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-weight: 400\">For more examples in context, I recommend checking out this <a href=\"https:\/\/www.youtube.com\/watch?v=qc8X71Nf2Kg\">video on color contrast<\/a>.<\/span><span style=\"font-weight: 400\">\u00a0It includes a demo of how to use an eyedropper tool to isolate a color to check for contrast.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">I hope this series has taken some of the overwhelm out of the principles of creating accessible content, and inspired you to learn more about accessibility.
