I have a card component, and I'm trying to place my title, subtitle at the right of my icon.It some how kept going down to the next line. I'm new to Vuetify.

<template>
    <v-container fluid class="my-5">
        <v-row>
            <v-flex col-xs-12>
                <v-card elevation="2" class="pa-5">
                    <v-flex xs3>
                        <v-btn text color="black">
                            <v-icon left large class="mr-5">{{ icon }}</v-icon>
                        </v-btn>
                    </v-flex>
                    <v-flex xs9>
                        <v-card-title>
                            {{ title }}
                        </v-card-title>

                        <v-card-subtitle> {{ subtitle }} </v-card-subtitle>
                    </v-flex>
                </v-card>
            </v-flex>
        </v-row>
    </v-container>
</template>
<script>
export default {
    name: 'MainPanel',
    props: {
        icon: String,
        title: String,
        subtitle: String
    }
}
</script>
<style></style>
