What makes Brackets different from other web code editors?
Try out Brackets:
The official download page provides the DEB packages for Debian / Ubuntu and their derivatives, such as Linux Mint, Elementary OS, and so forth.
Just download and double click the DEB to bring up Ubuntu Software Center and install it. Or run below commands instead once downloaded:
sudo dpkg -i ~/Downloads/brackets-sprint-*.deb; sudo apt-get -f install
Once installed, you can find it in Unity Dash.
