Yes it's always better to use classes and style them in a CSS 
file. However, in this instance these tags are used to give an 
immediate result regardless of whether or not an accompanying css 
file exists. We could also add classes to the spans in addition 
to the style tags in-case people wanted to use CSS files to style.
