For the first challenge I used HTML and .css to refactor a webpage. In order to optimize SEO and increase accessibility, semantic tags were used to accomplish this. The following criteria were used to guide the refactor process:
GIVEN a webpage meets accessibility standards
WHEN I view the source code
THEN I find semantic HTML elements
WHEN I view the structure of the HTML elements
THEN I find that the elements follow a logical structure independent of styling and positioning
WHEN I view the image elements
THEN I find accessible alt attributes
WHEN I view the heading attributes
THEN they fall in sequential order
WHEN I view the title element
THEN I find a concise, descriptive title
I used .css to style the navigation bar. I also consolidated the .css 
I used HTML to sort content into sections using semantic element tags. Sorted divs by article and section element tags.
