To avoid this problem, JavaScript can be used to make labels appear visually (in the associated label element) above or beside the input that has focus. Be aware that this makes it very hard for users to review the form. This same approach can be used to avoid visual redundancy of displaying both labels and placeholder text. ![]() Note: Section Hidden labels of this tutorial describes how to hide information visually but keep it available to assistive technology. Moreover, at the time of writing this tutorial, placeholder text is not broadly supported across assistive technologies and not displayed in older web browsers. Assistive technologies, such as screen readers, do not treat placeholder text as labels. While placeholder text provides valuable guidance for many users, placeholder text is not a replacement for labels. If the placeholder text contains instructional information or examples that disappear, it makes it more difficult for users to check their responses before submitting the form. Placeholder text is usually displayed with lower color contrast than text provided by users, and it disappears from form fields when users start entering text. Placeholder text provides instructions or an example of the required data format inside form fields that have not yet been edited by the user. ExampleĮxpiration date: MM/YYYY Placeholder text In the example below, form instructions indicate how required fields are marked, the expected format for the main data fields, and where to find additional help for each input. Provide such instructions before the element to ensure that it is read aloud by screen readers before they switch to “Forms Mode”. For example, indicate any required and optional input, allowed data formats, and timing limitations. Where relevant, provide overall instructions that apply to the entire form. It is critical to include form instructions in ways that can be read aloud. In this mode they usually only read aloud form elements such as, ,, , and. Important: Screen readers often switch to “Forms Mode” when they are processing content within a element. ![]()
