I like your photo selections and how the page doesn’t feel too cluttered.
The nav bar links aren’t taking me to the correct part of the page, though. I think if you have a:
< a href="#bookmark1" >About< /a >
link, you need a corresponding
< a id=“bookmark1” >< /a >
at the top of that particular section to link within the page.
Also, the contact me links aren’t working. For example:
< button id=“btn5” type=“button” class=“btn btn-info btn-lg” >< a href="** http://i.imgur.com/s85Xa.png **" target="_blank" > Github < /a >< /button >
should have your Github link in the bolded area and not a png.
