Node.js Chat App App styled Text

Ich machte eine Chat-App mit node.js, wo der Client einen Benutzernamen eingibt und kann dann Nachrichten senden. Er fügt die Nachricht in einem <ul> für die anderen Benutzer an, um zu sehen: "Benutzername: Nachricht". Ich wollte den Benutzernamen fett und blau machen. Wie kann es mit der geringsten Menge an Code gemacht werden?Node.js Chat App App styled Text
