Ionic has some CSS components where you can use Ionicons as a default which have preset styling. The range class in the item <div> will apply correct styling to both the input and the icons inside it.
Example
Another example of Ionicon usage in Ionic tabs which will create a tab like menu. The tabs-striped tabs-color-assertive classes define the style of the tabs themselves. Icons are used with simple <i> tags and they get their positional styling from the classes applied to the parent divs.
