Translation:How are you today?
样 literally means "form, format, kind, type, class." 怎么, or simply 怎, means "how, like what." 怎么样, or simply 怎样, literally means "like what kind" and therefore "how." Note that 么 doesn't have a concrete meaning, but it can be used to add the sense that the speaker is thinking of/about or considering something.
Similar to 怎样, if you've know what kind, you can use words such as 這样 ("this kind, like this") and 那样 ("that kind, like that").
