因此，我正在完成一项任务，并且在桌面上全屏显示，看起来很好。然而，在移动设备中，页面背景的顶部没有向右延伸，中间部分没有居中，底部没有向右延伸。另外，当我在浏览器中缩小页面时，顶部三分之一的文本会被截断而不是缩放。我有点失落，希望得到某种指导。我是web应用程序的新手。我已经包含的代码，以及链接到页面，我的仓库OIF代码 https://profile-josh-adams.herokuapp.com/ https://github.com/ender554/profile网站在手机中没有正确调整大小

I am a 37 year old student with an extreme eagerness to learn, and be
<br /><br />a key contributor in any profession. I love the academic setting and
<br /><br />the skills it has helped me build, but I understand that in this field it is
<br /><br /> most important to learn in a real world environment, and I hope to
<br /><br />extend my abilities greatly.
