Open a new file in Brackets. Save the File as yourname_yoga.css. Add the following styles to your css file:

1. Global styles for the document (remember to use body as the element selector) with background color of #F5F5F5; text color of #3F2860; and any san serif font (Arial, Verdana, etc).

2. Styles for the header element that configure background color #9BC1C2 with centered text using text-align.

3. Configure 200% line height (line-height) for the h1 element selector.

4. Styles for the nav element selector that configure centered (text-align) and bold (font-weight) font. Styles for the anchor elements only within the nav area to eliminate the default underline (hint: use nav a selector, text-decoration).

If you could please include the syntax that goes at the beginning of the file as well.
