Using an Icon with a Theme Link Button
In Combining Icon and Text in a Label, when an icon was used in a Label with a caption, we couldn't add more classes to style the text. That remains true but we can add other classes to style the text container. In this example, we'll add the ThemeLinkButton class.

As shown above, we've used a Label element, with a caption, and we've set the Class attribute value to:
fa fa-flag fa-lg pull-left ThemeLinkButton
The pull-left class is an FA class that left-justifies the icon and the ThemeLinkButton class has also been added.

And we can see the resulting Theme-based button shape and coloring above. In a live application, the button shading will change when the mouse cursor hovers over it.
