It looks like you put the correct path in the link in your header (in
index.html, but not
main.html), but not in your “see my works” button. When you notice that you have two buttons that should take you to same page, but only one of them works, it’s usually a pretty good guess that the proper path is in the working one
On another note, your portfolio is really coming together nicely. However, I have one suggestion to improve it from the user’s perspective. Currently, every time the user clicks on a link or button, the new page opens in a new tab. This becomes a lot of tabs very quickly if the user is trying to browse through each page. Changing this is as easy as removing
target="_blank" from your links and buttons.
Personally, I think it would provide a better user experience to have only the “Live Preview” buttons open new tabs, so you may want to consider experimenting with that. Of course, it’s all up to personal preference.
Keep up the good work and happy coding!
