Невероятные приключения флексбокса в фаерфоксе

• Блок с прокруткой в вертикальном флексбоксе не работает — ставить max-height: 100% на контейнер
• word-wrap: break-word не работает внутри флексбокса — спасает min-width: 0 на элементе флексбокса (overflow-x: hidden тоже работает)
• Флексбокс не работает на кнопке — класть внутрь блок и на нем делать флексбокс
• Элемент флексбокса с ellipsis расфигачивает все по ширине — min-width: 0 на флексбокс / max-width: 100% на самого верхнего разъехавшегося родителя
• Элементы флексбокса не выравниваются по базовой линии, если внутри еще один флексбокс — использовать inline-flex

Removing the last commit

To remove the last commit from git, you can simply run git reset --hard HEAD^ If you are removing multiple commits from the top, you can run git reset --hard HEAD~2 to remove the last two commits. You can increase the number to remove even more commits.

If you want to "uncommit" the commits, but keep the changes around for reworking, remove the "--hard": git reset HEAD^ which will evict the commits from the branch and from the index, but leave the working tree around.

If you want to save the commits on a new branch name, then run git branch newbranchname before doing the git reset.

"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

1. Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
2. Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
3. Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
4. To create the SSH keys, type ssh-keygen -t rsa -C "[email protected]". Th
