If the image is necessary for understanding the page content, equivalent information should be communicated as text using the alt attribute.
If the image is decorative and not necessary for understanding the page content, the alt attribute should be empty (alt="").
Example:
<img src="image.jpg" alt="">
All interactive elements are required to have descriptive text labels, including any links or form controls.
Example:
<label for="lastname">Last Name<label>
<input type="text" id="lastname">
When using italics, use sparingly as they cause problems for people with dyslexia.
Do not underline text, as this confuses normal content with links.
All iFrame code should have a title
Example:
<iframe width='500' height='294' src="#" title="Describe content of iframe"></iframe>
