added menu bar from code pen

i am going to adjust the width of each links space to give it more
padding and to account for making larger menu font
adjusted menu bar to link to my resume sections
turned of the active state over core strengths because i did not want to have that with the active color permanently on here when not hovered over.
adduced line height, padding to h1

along with added a page break to give space between heading 1 and
career overview
