Icon Only Button Icon only button visually hides the text content of the button. Such a button should be used sparingly and only in places where screen real estate is a concern. Important Notes: It is recommended that icon only buttons to be used in tandem with tooltip to give the user more context about the button’s function. When writing in plain HTML, aria-label is required to render the button text. For example: <button type="button" class="e-bolt-button e-bolt-button--icon-only" aria-label="Download">. Text should not be used inside the button when using aria-label. When writing in plain HTML, <span class="e-bolt-button__icon-center"> is required to wrap around the icon markup. The wrapper ensures that the icon will always center within the button. Demo File size: 25MB Add another row
