    mounted(){
        window.onresize = () => {
            return (() => {
            this.divHeight = window.innerHeight - yourHeight
            })();
        }
    },

    beforeMount() {
        this.divHeight = window.innerHeight - yourHeight
    },

data() {
    return {
        divHeight: 0
    }
}
