效果
大概的效果如下
主要都是用bootstrap的代码实现的
网站是照着 b站视频做的
查看视频教程
建议自己先看一遍文档再跟着视频写，不然可能看不懂
bootstarp中文文档
logo是从别人的站上扒的有点不太协调，不过不影响现在只要写出来就行，其他的以后再说
常用属性
只列举了一些，要想了解全还得看文档
m-：添加上下左右的margin。
mt-：添加顶部方向的 margin。
mb-：添加底部方向的 margin。
ml-：添加左侧方向的 margin。
mr-：添加右侧方向的 margin。
mx-：添加水平方向的 margin。
my-：添加垂直方向的 margin。
相当于margin，-后面跟的是数字
padding也是一样
p-：添加上下左右的padding。
pt-：添加顶部方向的 padding。
pb-：添加底部方向的 padding。
pl-：添加左侧方向的 padding。
pr-：添加右侧方向的 padding。
px-：添加水平方向的 padding。
py-：添加垂直方向的 padding
给div添加一下类可以实现水平垂直居中
row align-items-center justify-content-between
让图片变成圆形
rounded-circle
让图片缩小
w-50：让图片宽度缩小到50%
h-50：让 图片高度缩小到50%
盒子
d-flex相当于display：flex
d-none相当于display:none
完整代码
bootstrap的依赖自己去官网下载一个我用的版本是5.0.2
下载地址
https://www.getbootstrap.cn/docs/5.0/components/accordion/
下载好把下面html中的css，js换成自己下载的
图片也要自己的换一下
style.css
@media (min-width:768px) {
.news-input{
width: 50%;
}
}
body::before{
display: none;
content: "";
height: 56px;
}
