Sharing site error

I have created a Tribute Page for the second project of the Web Development course. My styling is applied to the html code, when i edit on FreeCodeCamp online. But when i try to share my site through Google Drive and Drive to Web the alignment of my items gets to the left of the page (instead of center) and some padding properties disappear. Although in the FreeCodeCamp editor these properties continue existing. Any idea of what might be wrong?
Thanks
