 arena/arena allocation <div id="arena"/> |  An _arena_ is a large memory buffer from which other memory allocations are made. This style of allocation is called _arena allocation_. See [this chapter](../memory.md) for more info.
 AST <div id="ast"/>                      |  The abstract syntax tree produced by the `rustc_ast` crate; reflects user syntax very closely.
 binder <div id="binder"/>                |  A "binder" is a place where a variable or type is declared; for example, the `<T>` is a binder for the generic type parameter `T` in `fn foo<T>(..)`, and \|`a`\|` ...` is a binder for the parameter `a`. See [the background chapter for more](./background.html#free-vs-bound).
-BodyId <div id="body-id"/                |  An identifier that refers to a specific body (definition of a function or constant) in the crate. See [the HIR chapter for more](../hir.html#identifiers-in-the-hir).
+BodyId <div id="body-id"/>               |  An identifier that refers to a specific body (definition of a function or constant) in the crate. See [the HIR chapter for more](../hir.html#identifiers-in-the-hir).
 bound variable <div id="bound-var"/>     |  A "bound variable" is one that is declared within an expression/term. For example, the variable `a` is bound within the closure expression \|`a`\|` a * 2`. See [the background chapter for more](./background.html#free-vs-bound)
 codegen <div id="codegen"/>              |  The code to translate MIR into LLVM IR.
 codegen unit <div id="codegen-unit"/>    |  When we produce LLVM IR, we group the Rust code into a number of codegen units (sometimes abbreviated as CGUs). Each of these units is processed by LLVM independently from one another, enabling parallelism. They are also the unit of incremental re-use. ([see more](../backend/codegen.md))
