Git Conflicts Explained: Why Do They Occur? How to Resolve Them Quickly?

Git conflicts are a common issue in collaborative work. When different versions modify the same file at the same location, Git cannot merge them automatically, requiring manual resolution. The core reason for conflicts is "modifications at the same location", such as multiple people editing the same file, version differences during branch merging, or conflicts between deletion and addition of content. Resolving conflicts involves three steps: First, after detecting a conflict, open the file and identify the markers automatically added by Git (`<<<<<<< HEAD` (your changes), `=======` (separator), `>>>>>>> branch-name` (changes from others)). Second, edit the content between the markers, choosing to retain or merge both parties' modifications. Third, execute `git add` to mark the conflict as resolved, then use `git merge --continue` or `git pull --continue` to complete the operation. Tools like VS Code can help quickly resolve complex conflicts. To prevent conflicts, develop habits such as frequently pulling code, committing in small steps, collaborative division of labor, and communication in advance. Remember the three-step process "identify markers → modify content → mark as resolved" to easily handle Git conflicts.
