404特效

更改之前创建好的404.vue:

<template>

    <div class="container">

        <vue-particles id="tsparticles" @particles-loaded="particlesLoaded"  :options="options"  />

            <div class="content">
                <div class="message">
                    <p class="message-heading">Error 404</p>
                    <p class="message-description">
                        The page you are looking for was moved, removed, renamed or might never have existed.
                    </p>
                </div>
                <div class="links">
                    <a href="http://localhost:3000/"></a>
