1. Basic implementation of video background
In actual development, we usually introduce video files through video tags and layout and style them in CSS to allow them to cover the background of the entire page.
1.1 Creating a video background component
We can create a standalone Vue component to encapsulate the functionality of the video background for reusing it in the project. The code is as follows:
<template>
<div class="background-video-container">
<video autoplay muted loop class="background-video">
<source :src="require('@/assets/backvideo/back.mp4')" type="video/mp4" />
Your browser does not support the video tag.
</video>
<!-- Slots for displaying page content -->
<div class="content">
<slot></slot>
</div>
</div>
</template>
In this template, the autoplay, muted and loop properties of the <video> tag can enable automatic playback, mute and loop playback of videos. Meanwhile, the <slot> slot is used to display the page content on the video background.
1.2 Configuration style
We hope that the video can be displayed in full screen and that the page content can be displayed on the upper layer of the video normally. The following is the corresponding CSS style:
<style scoped>
.background-video-container {
position: relative;
width: 100%;
height: 100vh; /* Full-screen video */
overflow: hidden;
}
.background-video {
position: absolute;
top: 50%;
left: 50%;
width: 100%;
height: 100%;
object-fit: cover; /* Make sure the video covers the entire background */
transform: translate(-50%, -50%);
z-index: 1; /* Video is placed at the bottom */
}
.content {
position: relative;
z-index: 2; /* The page content is placed on the upper layer of the video */
color: #ffffff; /* Make sure the content color is clearly visible on the video background */
}
</style>
-
.background-videouseobject-fit: coverAttributes to ensure that the video content covers the entire background area. -
.contentofz-indexSet to2, so that the page content is above the video background.
2. Layout and style of page content
With the video background, we also need to make sure that the page content is clearly visible on the background and adapt to a variety of different devices and screen sizes.
2.1 Layout of page content
Here is a simple example of page content layout:
<template>
<BackgroundVideo>
<div class="content-page">
<div class="content-container">
<div class="content-nav">
<el-breadcrumb class="breadcrumb" separator="/">
<el-breadcrumb-item>User Management</el-breadcrumb-item>
</el-breadcrumb>
</div>
<div class="content-main">
<!-- Form filter box -->
<div class="filter-box">
<el-form :inline="true" :model="filterForm" class="demo-form-inline">
<el-form-item label="username">
<el-input v-model="" placeholder="username"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" @click="onSubmitFilter">Query</el-button>
</el-form-item>
</el-form>
</div>
<!-- Table content area -->
<div class="form-table-box">
<el-table :data="tableData" style="width: 80%; margin: auto;" border stripe>
<!-- Table column definition -->
<el-table-column prop="userName" label="username" fixed="left" width="150"/>
<!-- Omit other columns -->
<el-table-column label="operate" width="150" fixed="right">
<template slot-scope="scope">
<el-button size="small" @click="handleRowEdit(scope.$index, )">edit</el-button>
<el-button size="small" type="danger" @click="handleRowDelete(scope.$index, )">delete</el-button>
</template>
</el-table-column>
</el-table>
</div>
<div class="page-box">
<el-pagination background @current-change="handlePageChange" :="page" :page-size="10"
layout="total, prev, pager, next, jumper" :total="total"/>
</div>
</div>
</div>
</div>
</BackgroundVideo>
</template>
In this page layout,el-breadcrumb、el-formandel-tableComponents are used to showcase the basic user management interface.
2.2 Content container style
We want the content container to have a translucent background so that users can see the background video and browse the page content clearly. The corresponding CSS is as follows:
<style scoped>
.content-page {
display: flex;
justify-content: center;
align-items: center;
height: 100vh;
}
.content-container {
background-color: rgba(255, 255, 255, 0.8); /* Translucent background */
padding: 20px;
border-radius: 10px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.1); /* Shadow effect */
}
.form-table-box {
display: flex;
justify-content: center;
}
.page-box {
display: flex;
justify-content: center;
margin-top: 20px;
}
</style>
By adjustingcontent-containerofbackground-colorIt is translucent white, which can prevent the video background from being too abrupt, and at the same time makes the page content highly readable.
3. Frequently Asked Questions and Solutions
3.1 The problem of video not being able to cover full screen
In some browsers or resolutions, videos may not fully cover the entire page. This can be adjusted by the following style:
.background-video {
object-fit: cover;
width: 100vw;
height: 100vh;
}
3.2 Video loading performance issues
The video background will have a certain impact on the loading performance of the page, especially on the mobile side. It is recommended to use compressed short videos in actual projects, or use video files with lower resolution.
3.3 Video compatibility issues
Different browsers support different video formats. It is usually recommended to use videos in mp4 format, and you can add webm or ogg formats to improve compatibility.
4. Summary
Through the above steps, we have achieved a full-screen video background effect and ensured the readability of the page content. Video background can greatly improve the visual effect of the web page, but it needs to be designed reasonably to ensure loading performance and browsing experience. I hope that the explanation in this article can help you achieve similar design effects in your project!
