Final answer:
When adding values to acceptFrom=, rules are separated with commas or spaces to define a set of allowed sources or parameters, typically within web technology configurations like HTML or CSS.
Step-by-step explanation:
When adding values to acceptFrom=, we separate rules with commas or spaces. This syntax is used to specify a set of rules or allowed sources for web technologies such as HTML and CSS. For example, if we want to define multiple email addresses from which we can accept input or resources, we would list them separated by either a comma or a space.
To explain further, if you are editing a configuration file or a piece of code, and you need to add multiple values to a property like acceptFrom=, you make sure to delineate each value so that the system can recognize them as separate entries. For instance, in an HTML form element, you might define multiple MIME types that a file input can accept using commas or spaces to separate them.
