If you try to run an audit check from Google or any other services, you might get an accessibility error saying that, “Buttons do not have an accessible name”.
When a button doesn’t have an accessible name screen readers and other assistive technologies announce it as button.
When someone who is a disabled and using hearing devices or any other means to get access to your website, the button will no serve any purpose. Because it will provide no information to users about what the button does.
How to add accessible names to buttons
For buttons with visible labels, add text content to the button element.
Make the label a clear call to action.
For buttons without visible labels, like icon buttons, use the aria-label attribute to clearly describe the action to anyone using an assistive technology.
<button class="btn" aria-label="Left Arrow"> <span class="class-name" aria-hidden="true">left_arrow</span> </button> OR <button aria-label="Close" onclick="myDiv.close()">X</button>
The aria-label attribute
The aria-label attribute is used to define a string that labels the current element.
We can use it in cases where a text label is not visible on the screen.
If there is visible text labeling the element, use aria-labelledby instead.
This attribute can be used with any typical HTML element; it is not limited to elements that have an ARIA role assigned.
