How do I modify my .gitignore file by adding !*.css at the end?

Question

I'm new to pulling/pushing code and gitignore, and I can't figure out how to modify the .gitignore file.

Answer 1

You can simply do:

echo "!*.css" >> .gitignore
git add .gitignore
git commit -m "Whitelist css files"
git push -u origin master

That would update your .gitignore file.
