Add-Breadcrumb-to-Sign-up-Page

[karlasanc]

Resolve #27: I made modifications on two files (signup.html & signup.css).

• Within the signup.html document, I enclosed the breadcrumb unordered list within navigation HTML tags to add semantic meaning, used the aria-label attribute to ensure it is compatible with accessibility devices, and added a breadcrumb class to the navigation tags to style it with CSS. The home list item includes an anchor tag with a href attribute that links the index.html page for users to go back.

• Within the signup.css document, I used the class selector to change the unordered list from vertical to horizontal using the display attribute, removed the bullet points using the list-style attribute, and changed the color to separate the breadcrumb nav from the sign-up form. I targeted the space between list items to include padding and forward slashing using "/\00a0".
