✨哈喽，进来的小伙伴们，你们好耶！✨
🛰️🛰️系列专栏:【JavaWeb】
✈️✈️本篇内容:从0到1构建一个博客系统！
🚀🚀代码托管平台github：博客系统源码托管！
⛵⛵作者简介：一名双非本科大三在读的科班Java编程小白，道阻且长，星夜启程！
哈喽，大家好，我是辰柒。那么前面已经把JavaWeb部分知识点已经更新完毕了，那我们学习完了前端三剑客是不是需要做出点什么呢？做一个小项目？没错！今天呢，我们就用之前学习的知识点来从零到一写一个简单的前端页面。
那么学习本篇博客之前，你需要学完这些东西：前端三剑客的基础知识点！
如果你想学习更多的知识，欢迎加入博主的个人社区：Java-面向大厂编程！
社区活动多多，目前已被评选为2022个人社区之星，后期社区活动奖励，五份CSDN定制背包！
社区还需要几位管理员，有意向的童鞋可以在文章末尾加我vx，把csdn的id号发给我就可以给你上管理员啦，管理员可以直接同步你的文章到我们的社区喔，让更多的人看到你的博客！！
如果觉得博主写的不错，可以点个关注，点个红星，感谢大家的支持！
**本项目主要分成四个页面: **
博客列表页 ：显示了当前系统中都有哪些发布出来的博客
博客正文页 ：显示了当前博客的详细信息。
博客登陆页 ：包含了一个登录框，输入用户名，密码，登录按钮。
博客编辑页： 包括一个输入框，Markdown编辑器(使用第三方组件)
博客列表页代码：blog_list.html

OK，接下来我们需要创建一个目录image用来存放我们的头像，背景，logo三张图片，注意必须将目录的地址放在这个博客系统的文件目录里面，这样才能访问到我们的图片，不然最后是运行不出来效果的！
step1：
step2：
注意这里的Markdown编译器我们直接引入现成的嵌入到我们的页面即可！
1、下载editor.md并且拷贝项目目录中。
下载地址：editor.md官网
2、选择通过github下载。
** 3、将压缩包解压至对应的项目文件目录下，文件夹名字就写成 editor.md ，注意必须是这个名字，不能是其他的，否则会影响到我们代码中的引用。**
此外还需要安装另一个库，jQuery，直接在官网下载即可！
浏览器输入：jquery cdn官网。
对应下面这个界面：
下载链接：jquery mdn下载地址！
因为js 是需要通过网络来加载的. 期望内容尽量短,从而节省带宽minified 版本就是属于被压缩过的.(去掉空格换行之类的,把变量名替换成 abcd 这种)。
然后打开jquery的源码文件，直接复制粘贴到VSCode中，保存为jquery.min.js这个文件中。
OK，到这里就可以去运行我们的项目啦！
完整源码获取地址：博客系统github托管地址！
觉得本文对您有所作用的话可以个github点个stars，后期会继续更新后端开发相关知识点，期待您的关注！
