Introduction to git Git is a distributed version control system, which means that each developer has a complete copy of the code base on their computer. This is different from a centralized version control system (such as Subversion or Perforce), which only has a central code repository. The benefit of distributed version control is that it makes collaboration more efficient because developers can work offline and synchronize with the central code base later. Installing Git To use Git, you need to install it on your computer first. You can download the installer for your operating system from the official Git website.

There can be multiple forms in html5. The rules allow multiple form tags to be used in the same HTML page. However, in order to prevent the backend from not recognizing it when submitting, you need to add different IDs or classes to the form.
