 You can do that, with the [`<ErrorBoundary/>`](https://docs.rs/leptos/latest/leptos/fn.ErrorBoundary.html)
 component.
 
+```admonish note
+People often try to point out that `<input type="number>` prevents you from typing a string 
+like `foo`, or anything else that's not a number. This is true in some browsers, but not in all!
+Moreover, there are a variety of things that can be typed into a plain number input that are not an
+`i32`: a floating-point number, a larger-than-32-bit number, the letter `e`, and so on. The browser
+can be told to uphold some of these invariants, but browser behavior still varies: Parsing for yourself
+is important!

 ## `<ErrorBoundary/>`
 
 An `<ErrorBoundary/>` is a little like the `<Show/>` component we saw in the last chapter.
