Hello, I'm studying a new area for myself - "frontend". The question arose - Where can I find good lessons about cross-platform and cross-browser compatibility?

Answer 1

They have been learning this for years and constantly honing their skills. There is no such lesson that can tell you about all the intricacies of cross-browser layout.

Answer 2

To do it cross-browser only 2 conditions must be observed:
1. Use Normalize.css
2. View the results of work and check the functionality in all available browsers and on all available devices. You must have all major browsers: Chrome, FF, Opera, IE, Edge. For older versions of IE, you must have virtual machines ( they are free ). It is also desirable to have a couple of mobile devices (for example, buy a used iPhone, android and some kind of tablet like an iPad for cheap).
That's actually all. You will get the main problems with cross-browser compatibility when developing under IE < 11, so you will learn in practice where and what. The main thing is immediately, after each completed block, immediately see the result in all browsers.
