Question

You need to organize a video conference between the team in the office and the manager in another place. I am completely unfamiliar with the topic. What software, hardware, microphones... A group of people is sitting in front of a monitor in the office. A camera is pointed at them, they look at the monitor, there are speakers and somewhere a microphone or several. Immediately the problem is, the microphone will be phoning in the speakers, how to connect several microphones, or each with a wireless headset. What software / hardware to use, which is better to run a server in the cloud or locally on your computer. In general, a lot of questions. The manager wants a video conference either at the computer or on a smartphone. Desirable excellent sound and picture.

I'll add to the comment above: do not use containers with a fixed size either, it's best to set block sizes in percentages, padding too.
Don't forget to work with fonts and line-height (also not set in px), because on large screens with a fixed font size, the text will look terrible.
