Respect default font size preference from browsers

We encountered an issue where PolyGerrit was not respecting browser
font preferences. Browser font preferences include both a default font
size and a minimum font size.

In the event that a font declared in px is smaller than the minimum font
size, the size is increased to equal the minimum font size. However,
if the font is declared in px and greater than the minimum, the
preferred font size is not taken into account.

Browsers' default font size is 16px [1], So instead of declaring the
base font in px (previously 13px), this change makes it a percentage
of the default font size. If the user has changed their default, this
is taken into account.

From this point, all other fonts will be declared in rems, which makes
it easier to base the new size off of the base font size of the <html>
tag, rather than ems which bases it on the container[2]. This allows us
to declare font sizes in a way more similar to pixels, yet relative.

A follow-up change will change all font size declaration to use rem from
em for consistency.

Gerrit Code Review

Gerrit is a code review and project management tool for Git based projects.

Build Status

Objective

Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.

Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.

Documentation

For information about how to install and use Gerrit, refer to the documentation.

Source

Our canonical Git repository is located on googlesource.com. There is a mirror of the repository on Github.

Reporting bugs

Please report bugs on the issue tracker.

Contribute

Gerrit is the work of hundreds of contributors. We appreciate your help!

Please read the contribution guidelines.

Note that we do not accept Pull Requests via the Github mirror.

Getting in contact

The IRC channel on freenode is #gerrit. An archive is available at: echelog.com.

The Developer Mailing list is repo-discuss on Google Groups.

Build

Install Bazel and run the following:

    git clone --recursive https://gerrit.googlesource.com/gerrit
    cd gerrit && bazel build release

Install binary packages (Deb/Rpm)

The instruction how to configure GerritForge/BinTray repositories is here

On Debian/Ubuntu run:

    apt-get update & apt-get install gerrit=<version>-<release>

NOTE: release is a counter that starts with 1 and indicates the number of packages that have been released with the same version of the software.

On CentOS/RedHat run:

    yum clean all && yum install gerrit-<version>[-<release>]

On Fedora run:

    dnf clean all && dnf install gerrit-<version>[-<release>]

Use pre-built Gerrit images on Docker

Docker images of Gerrit are available on DockerHub

To run a CentOS 7 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-centos7[:version]

To run a Ubuntu 15.04 based Gerrit image:

    docker run -p 8080:8080 gerritforge/gerrit-ubuntu15.04[:version]

NOTE: release is optional. Last released package of the version is installed if the release number is omitted.
