-The distinctive feature of ERC1155 is that it uses a single smart contract to represent multiple tokens at once. This is why its {balance_of-api} function differs from ERC20’s and ERC777’s: it has an additional id argument for the identifier of the token that you want to query the balance of.
+The distinctive feature of ERC1155 is that it uses a single smart contract to represent multiple tokens at once. This is why its {balance_of-api} function differs from ERC20’s and ERC777’s: it has an additional `id` argument for the identifier of the token that you want to query the balance of.
 
 This is similar to how ERC721 does things, but in that standard a token id has no concept of balance: each token is non-fungible and exists or doesn’t. The ERC721 balance_of function refers to how many different tokens an account has, not how many of each. On the other hand, in ERC1155 accounts have a distinct balance for each token id, and non-fungible tokens are implemented by simply minting a single one of them.
