Customize Built-in Pager Components

I'm currently utilizing the kendoPagerTemplate within a grid. In the template I am using the built-in elements of:
PagerNextButtonsComponent
PagerNumericButtonsComponent
PagerPageSizesComponent 
PagerPrevButtonsComponent

I noticed that they generate kendo buttons and dropdown lists with classes that are from appearance options applied to them. Is there a way to choose which options they are, or am I forced to use CSS to select those class names and modify them to look like a different appearance option?
