Custom output styles and EndNote web

We have some output styles which have been edited in EndNote X7. Is it possible to use these custom output styles in EndNote Web? When the two libraries are synced, will the custom output styles also sync? Thanks.

While performing the Sync operation, custom content files (Output styles, Connection files & Import Filters) are not synced.

If you wish to use custom output styles on the online version of EndNote, you should get in touch with the EndNote online administrator (librarian) at the university from which you have activated the EndNote online account. If you have activated the EndNote online account from EndNote desktop software alone, then this is not possible.
