1.设置整个页面为蓝色
在样式中将body设置为蓝色
<style>
body{
/* background-color: 'url('+requird('../../assets/img')+')'; */
background-color: blue;
}
</style>
2.将图片设为背景
方法一:(不好控制图片的属性设置)
<style>
body{
/* 将图片设为背景 */
background-image: url(../../assets/img/2.jpg) ;
/* 将图片设为不平铺 */
background-repeat: no-repeat;
}
body .login{
/* 设置背景图片大小 ,相对于body为100%*/
background-size: 100% 100%;
/* background: rgba(34,34,34,0.5); */
}
方法二(优选):
<template>
<!-- 存放背景图片 -->
<div class="background">
<!-- img中的宽高设置图像尺寸,宽高100%是为了让整个图像显示在页面 -->
<img :src="imgSrc" width="100%" height="100%" />
</div>
<!-- 存放登录表单 -->
<!-- <div class="front">
<p>登录:<input type="text" name="lo" /></p>
<p>注册:<input type="text" name="re" /></p>
</div> -->
</template>
<script>
export default{
data(){
return{
imgSrc:require('../../assets/img/2.jpg')
}
}
}
</script>
<style>
.background{
/* 宽高100%是为了铺满屏幕 */
width: 100%;
height: 100%;
/* z-index用来确定层叠关系,值大的显示在值小的上面 */
z-index: -1;
position: absolute;
/* 调节背景图片透明度 */
opacity: 0.3;
}
</style>
效果图:
3.在背景图的基础上添加一个登录框
(1)使用el-input组件时,
①v-model属性一定要存在,不然会出现无法输入的问题
②通过placeholder将文字显示出来
③通过prefix-icon="el-icon-phone"在输入框前面添加图标
④通过style="width: 250px;"设置输入框的长度
(2)将某个块设置为中心位置
top、left是以左上角为原点,因此平移以后不处于中心位置
加上translate(-50%, -50%)的作用是,往上(x轴),左(y轴)移动自身长宽的50%,因此就可以居于中心位置了
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
(3)只设置背景颜色透明度可以使用rgba
如
background: rgba(34,34,34,0.1);
