Buttons with icon
Using icons in buttons can help to enhance the UX. Add an icon inside any style button with a label. Place the icons before label in order for users to see them first.
Add EOS-icons or material design icon inside any style of button to create a button with an icon.
Only icon buttons
If an icon button has no label be sure to use a tooltip to offer some short explanation of the buttons purpose.
You can create an icon-only button, by adding an EOS or Material design icon inside any style of button without a text label.
