How can I vote a good practice?

Users can vote on specific content such as good practices. To vote a practice firstly, they have to browse or search for it and visit it. At the bottom of each practice they will find a table with the overall rate of a practice and the criteria they can vote.

User can give stars or vote for specific criteria as the image above indicates. Users can also correct their vote in case of giving a vote by mistake. To take back or correct their vote, they must click again the item they clicked by mistake. For instance, if a user voted for "Transferable", he/she can take back this vote by clicking again this criteria. The same applies with the star voting system.
