# Sometimes you need to move your existing git repository

# Here are a simple and quick steps that does exactly this.
#
# Let's assume we call "old repo" the repository you wish
# to move, and "new repo" the one you wish to move to.
#
### Step 1. Make sure you have a local copy of all "old repo"

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

1. Set -moz-appearance to none. This will "reset" the styling of the element;
2. Set text-indent to 0.01px. This will "push" the text a tiny bit^[1] to the right;
