Technique G211:Matching the accessible name to the visible label


Content implemented in any technology.

This technique relates to 2.5.3: Label in Name (Sufficient).


When speech input users interact with a web page, they usually speak a command followed by the reference to some visible label (such as text beside an input field or inside a button or link). For example, they may say "click search" to activate a button labelled Search. When speech recognition software processes speech input and looks for matches, it uses the accessible name of controls. Where there is a mismatch between the text in the label and the text in the accessible name, it can cause issues for the user. The simplest way to enable speech input users and meet 2.5.3 Label in Name is to ensure that the accessible name matches the visible text label.

Sometimes more than one text string will be positioned in the vicinity of a control that could be considered a candidate for its label. For example, a set of inputs that each have their own labels may also be preceded by a heading, an instruction or a group label (such as an HTML legend/fieldset or an ARIA group or radiogroup). Note that the term "group label" means something different than "label", both programmatically and in regard to 2.5.3 Label in Name.

The Understanding 2.5.3 Label in Name document recommends that only the text string adjacent to or in close proximity to an input should be treated as the label when assessing a control's label for the purposes of meeting 2.5.3 (see the section "Identifying label text for components"). There are both practical and technical reasons for restricting the designation of an input's label in this way. The technical reasons are discussed in the Understanding document's section called Accessible Name and Description Computation specification.


Mapping a visible label to the accessible name is achieved in many technologies by meeting 1.3.1 Information and Relationships through the proper use of native semantics. Many controls derive accessible names by correct nesting of elements, while other elements have specific attributes which are a valid means of providing or referencing an accessible name.

The accessible name should be assigned through native elements and semantics where possible. That helps ensure an exact match between the visible label and name.

Example 1: Anchor text provides both the link's label and its accessible name

Using conventional HTML, the text between the anchor element's tags provides both the link's visible text and the accessible name "Code of conduct":

<p>Go to our <a href="url-to-page-about-code.html">Code of conduct</a></p>

Example 2: Text in label element provides name for input via for attribute

The text between the label tags also serves as the checkbox input's accessible name "Notify me of delays" by using the for attribute which references the id of the input.

<input type="checkbox" id="notification" name="notify" value="delays">
<label for="notification">Notify me of delays</label>

Example 3: The button text provides the accessible name

The text inside a button element becomes both its visible label and its accessible name:

Example 4: Simple Radio Button Group

Radio buttons typically appear in a group, where each button is labelled and the group of buttons is preceded by information which explains or categorizes the group.

Call me when balance exceeds $10,000, Yes No
Figure 1 "Call me when balance exceeds $10,000 radio group, with Yes and No choices

The label for each component should be restricted to "Yes" and "No". To meet 1.3.1 Information and Relationships and 3.3.2 Labels or Instructions, the "Call me…" text can be coded to convey the relationship to ATs, in this example by using a fieldset and legend.

If the label is not restricted to the string adjacent to the radio button, multiple interpretations of what constitutes the label can result in less uniform functionality. If "Yes" alone is not the label for the first radio button, is it "Call me when balance exceeds $10,000"? Or is it a combination of text strings, in which case is the order "Call me when balance exceeds $10,000 Yes" or "Yes, Call me when balance exceeds $10,000"? Decisions to combine text strings can have negative effects on screen reader users since the order of concatenation can affect meaning. In this example, "No, call me when balance exceeds $10,000" could be very confusing to a screen reader user.

<legend>Call me when balance exceeds $10,000?</legend><br />
<input type="radio" id="yes" name="callme" value="yes">
<label for="yes">Yes</label>
<input type="radio" id="no" name="callme" value="no">
<label for="no">No</label>

Example 5: Checkbox Groupings

For checkbox groupings, implementations that attempt to incorporate more than just the immediate checkbox label into the accessible name can also be problematic if not isolated to the adjacent text string.

What do you value in our service? (Check all that apply) Courtesy, Promptness, Store Hours, Knowledge
Figure 2 What do you value in our service? checkbox group, with 4 choices.

In Figure 2, there is a long text string that combines a group label and instruction, "What do you value in our service (check all that apply)?" Each of the checkboxes also has its own one- or two-word label. In regard to 2.5.3, the labels for the components should be restricted to "Courtesy", "Promptness", "Store Hours" and "Knowledge".

Attempting to include the preceding text as part of the accessible name can potentially make it more difficult to isolate a control by spoken commands for speech-input users. Such a construction will also negatively increase verbosity for screen reader users (with the combined text strings read out for each of the inputs before the input's state). The simplest solution is to restrict the accessible name to the text immediately beside the checkboxes, using similar techniques to those for the standard radio button group.

Example 6: Stacked Labels

Although labels for comboboxes, dropdown lists, text inputs, and other widgets are typically oriented immediately to the left of the component, there is an alternative established convention where labels are stacked above the inputs, aligned with their left edge.

two inputs labelled Email and Password
Figure 3 Two inputs with the labels positioned above and to the left.

In Figure 3, the inputs are stacked and left-aligned, with the labels immediately preceding each input, also left-aligned. There is additional white space between the label and the preceding input so that the label is closest to its associated text input. Stacked labels are relatively common in mobile designs, where horizontal space is constrained.

Figure 4 shows a variation on stacked labels, where hints and guidance are included between the label and the input. This design does not provide an adjacent label. However, the "New Password" label is still considered to be in close enough proximity, especially given its size and boldness relative to the smaller and lower-contrast guidance text. The associations are reinforced programmatically, where the hint text is given a role of aria-describedby and the label is properly associated with the input.

New Password. Passwords must be 10 or more characters, and contain at least one capital, numeric and non-alphanumeric.'
Figure 4 New Password label positioned above input with a smaller-point text string about the password requirements positioned between the large label and the input.

The hint text in such implementations should be kept to a single line where possible, since accessibility issues can arise where a more lengthy hint separates the label from its input. Figure 4 illustrates that the concept of "adjacent text" is a guide for label interpretation, but cannot always serve as a hard rule.

<label class="label" for="example-2">
<span id="example-2-hint" class="hint">
Passwords must be 10 or more characters, and contain at least one capital, numeric and non-alphanumeric.
<input class="input" id="example-2" name="example-2" type="text" aria-describedby="example-2-hint">

Example 7: Range of inputs with few labels

A less common disparity between labels and inputs can occur when a group of radio buttons is set up to elicit a choice across a range. The labels may only be located at each end of the range or may be interspersed at various points in the range.

Rate your response, Hated it, Loved it
Figure 6 Line of 5 radio buttons with Hated it and Loved it labels at each end

The two labels, "Hated it" and "Loved it", are adjacent to the first and last radio buttons, and should be their accessible names. Speech-input users can speak either of these labels to select a radio button, and then use arrow navigation (e.g., "Press right arrow") to modify the selection. "Rate your response" is the text describing the whole widget and can be associated as the group label (here using legend). The three middle radio buttons do not have visible labels. In the code example they are given title attributes of "Disliked", "So-so" and "Liked" in order to meet 3.3.2 Labels or Instructions.

<legend>Rate your response</legend>
<label for="hated">Hated it</label>
<input type="radio" name="meal" id="hated" value="hated">
<input type="radio" name="meal" id="poor" value="poor" title="Disliked">
<input type="radio" name="meal" id="neutral" value="neutral" title="So-so">
<input type="radio" name="meal" id="okay" value="okay" title="Liked">
<input type="radio" name="meal" id="loved" value="loved">
<label for="loved">Loved it</label>
