[Vuejs]-My Vuetify element has an unexpected margin, how do I remove it?

You need to add the fluid property to v-container which fully extends the width.

To remove the default margin add ma-0 property to component class property

To remove the default padding add pa-0 property to component class property

Actually, the theme installed site is distracting. If you want to define your custom property then use !important suffex to css property. e.g margin: 10px !important;
