Study Notes: Document Object Model (DOM)
💡 Easy English Concept Guide
GitHub is a cloud platform where developers store their Git repositories to back up code and collaborate with team members.
1. Local Repositories vs Cloud Remotes
Git manages history files locally on your computer. GitHub is a cloud storage platform for these files, allowing you to back up your codebase online and collaborate with other developers.
2. Push and Remote Syncing Workflow
# Add link to remote GitHub repository
git remote add origin https://github.com/vegan/wd-classroom.git
# Rename main branch to default
git branch -M main
# Upload local commits to remote GitHub master branch
git push -u origin main
# Retrieve updates from GitHub remote repo
git pull origin main💡 Quick Revision Guide
Ensure your layouts adapt cleanly across responsive viewport widths. Double-check script sequences to verify that DOM selections happen after nodes are parsed by the browser.
