Time-saving browser synchronization test tool
Browsersync allows the browser to instantly and quickly respond to your file changes (HTML, JS, CSS, sass, less, etc.) and automatically refresh the page. More importantly, Browsersync can be in the PC, tablet, mobile phone and other equipment input debugging . You can imagine: "Suppose your desk has a PC, ipad, iphone, Android and other devices, while opening the page you need to debug, when you use Browsersync, any time you save your code, the above device will show your changes at the same time." Whether you're a front-end or back-end engineer, using it will increase your productivity by 30%.
With it, you don't have to switch back and forth between multiple browsers, multiple devices, and refresh the page frequently. What's even more amazing is that you can scroll through the pages in one browser, click, and so on and sync to other browsers and devices, all of which are also controlled by a visual interface.
