Input buttons must have discernible text

Screen reader users cannot understand the purpose of an image without a discernable and accessible textual name. A title for an image may provide only advisory information about the image itself. Unnamed actionable graphic images such as buttons have no clear description of the destination, purpose, function or action for the non-text content when it is intended to be used as a control.

Fixing the problem

Correct markup solutions

Eleven markup patterns pass the input-button-name test criteria:

<form action="#">
<input type="button" id="pass1" value="Button Name" />
<input type="button" id="pass2" aria-label="Name" />
<input type="button" id="pass3" aria-labelledby="labeldiv" />
<input type="button" id="pass4" value="Name" aria-label="Aria Name" />
<input type="submit" id="pass5" />
<input type="submit" value="Something" id="pass6" />
<input type="reset" id="pass7" />
<input type="reset" value="Something" id="pass8" />
<input type="button" title="Something" id="pass9" />
<input type="submit" title="Something" id="pass10" />
<input type="reset" title="Something" id="pass11" />
</form>

Incorrect markup solutions

Five markup patterns fail the input-button-name test criteria:

<form action="#">
<input type="button" id="fail1" />
</form>
<form action="#">
<input type="button" id="fail2" aria-label="" />
</form>
<form action="#">
<input type="button" id="fail3" aria-labelledby="nonexistent" />
</form>
<form action="#">
<input type="button" id="fail4" aria-labelledby="emptydiv" />
<div id="labeldiv">Button label</div>
<div id="emptydiv"></div>
</form>
<form action="#">
<input type="submit" value="" id="fail5" />
</form>
<form action="#">
<input type="reset" value="" id="fail6" />
</form>
