 ### Style Sanitization for `[style]` and `[style.prop]` bindings
 Angular used to sanitize `[style]` and `[style.prop]` bindings to prevent malicious code from being inserted through `javascript:` expressions in CSS `url()` entries. However, most modern browsers no longer support the usage of these expressions, so sanitization was only maintained for the sake of IE 6 and 7. Given that Angular does not support either IE 6 or 7 and sanitization has a performance cost, we will no longer sanitize style bindings as of version 10 of Angular.

-The *statement context* is typically the component instance.

+Statements can refer only to what's in the statement context, which is typically the component instance.
+For example, `deleteHero()` of `(click)="deleteHero()"` is a method of the component in the following snippet.
 
 <code-example path="template-syntax/src/app/app.component.html" region="context-component-statement" header="src/app/app.component.html"></code-example>
 
 The statement context may also refer to properties of the template's own context.
-In the following examples, the template `$event` object,
-a [template input variable](guide/built-in-directives#template-input-variable) (`let hero`),
-and a [template reference variable](guide/template-reference-variables) (`#heroForm`)
-are passed to an event handling method of the component.
+In the following example, the component's event handling method, `onSave()` takes the template's own `$event` object as an argument.
+On the next two lines, the `deleteHero()` method takes a [template input variable](guide/built-in-directives#template-input-variable), `hero`, and `onSubmit()` takes a [template reference variable](guide/template-reference-variables), `#heroForm`.

+In this example, the context of the `$event` object, `hero`, and `#heroForm` is the template.
+
 Template context names take precedence over component context names.
-In `deleteHero(hero)` above, the `hero` is the template input variable,
-not the component's `hero` property.
+In the preceding `deleteHero(hero)`, the `hero` is the template input variable, not the component's `hero` property.
 
-## Statement guidelines
+## Statement best practices
 
-Template statements cannot refer to anything in the global namespace. They
-can't refer to `window` or `document`.
-They can't call `console.log` or `Math.max`.
+* **Conciseness**
 
-As with expressions, avoid writing complex template statements.
-A method call or simple property assignment should be the norm.
+  Keep template statements minimal by using method calls or basic property assignments.
+
+* **Work within the context**
+
+  The context of a template statement can be the component class instance or the template.
+  Because of this, template statements cannot refer to anything in the global namespace such as `window` or `document`.
+  For example, template statements can't call `console.log()` or `Math.max()`.
