Why doesn't the browser update the changed styles during development?

Question

css

For clarity, I will give an example.
I make up the page, I change something in the styles, I refresh the page in the browser, but nothing changes. I open it in another browser - everything is displayed in accordance with the changes made, I change the URL from localhost: 7777 to 127.0.0.1: 7777, for example - again everything is ok. However, this is exactly until the next style change. That is, the browser remembers its state and ignores any change to them.
By the way, it all started when I was writing some application in JS. And so I took up Angular.js and at some point this problem arose again. Although I'm pretty sure that's not the point.
Browsers: Safari, Chrome and Firefox.
