Hi there!

1. I created a list of buttons for the implied filtering system. See-- .topic-tags-list, .topic-tag, and .topic-tag-btn. I thought that if tags can be added and subtracted, a list would be preferable here. I also used buttons for in-page filtering, but I suppose anchors could be used if the filtering system is not in-page. I would like to know if this is semantically correct, and if my reasoning is sound?

2. I had added a "line-height: 150%" to the body style, thinking it would apply to all text. This property did not affect the headings or button. I had to go back and include this property in their classes as well. Why is this?

Thank you!!
