This project has two parts: Part 1 - Correct HTML code problem issues for webpage: [login to view URL] Background: This page is generated from a custom Big Commerce template I created. The template html code is in zip file [login to view URL] This zip also contains file from W3C inicating 37 errors and 4 warnings generated by the [login to view URL] template in combination with other Big Commerce template, panel and snippet code. The objectives are to 1- clean this code to pass the W3C test with no errors. 2 - advise changes in page html to properly inlude temptates and other code from Big Commerce.
