Web page isn't getting responsive

I want to make my web page responsive. It works till 320px, but when I reduce the size of the screen furthermore, it doesn't work at all, and only half of the content gets visible.

Here's the required code

Angular and Angular Dart (and Flutter)

I've been thinking about using Angular Dart, right now I'm using Angular and TypeScript and it's a really good framework, but I tried Flutter and I absolutely loved it, it was perfect, the widgets, the language, everything just just worked perfectly together. So I saw that I can use Angular with Dart, it had a great documentation, includes material design, so I started to look into it and I barely found anything about it, sure it has pub with all the packages, but most of them are for Flutter, I noticed I can only use choco with cmd in admin mode to run the webdev serve and some other flaws that didn't really like, and also the community seems dead. In december Flutter announced that they are working on Hummingbird (Flutter for the web) and they are going cross-platform, and I can't wait to see what they will come up with, and I want to start moving towards Flutter, but I have new projects, so I can't wait for Hummingbird right now, now I have to decide if we're going to use Angular, or Angular Dart. What are your opinions on this matter? What would you choose right now?

Is it possible to integrate or use information of some other web application on your website ? on Real Time?

According to my title, Is it possible to integrate or use information of some other web application on your website ? on Real Time?

For Example#1: I have a Facebook page and I post daily. Is it possible that I integrate it to my website? Not my whole Facebook page but only post part (post component). Means view that part of a Facebook page on my website. Or can I use that Facebook post DATA on my website.

Example#2: If example#1 is not possible? So I'm keeping it more simple that can we use DATA of some other web application on our website? Means If it is updated on that web application so automatic it should updated on our website also (on Real time).

How it can be done through API? If that web application is providing? what if not providing? Or any other solution?
