Git Submodules basic explanation

Why submodules?

In Git you can add a submodule to a repository. This is basically a repository embedded in your main repository. This can be very useful. A couple of advantages of using submodules:

• You can separate the code into different repositories.

For example, to override the AppBar (https://material-ui-next.com/api/app-bar/) root class we can do the following:

First method (override Material UI classnames):
1 - Add the property classes in the AppBar component:
    <AppBar classes={{root: 'my-root-class'}}
2 - Override the styles with the styled components:
    styled(AppBar)`
      &.my-root-class {
        z-index: 1500;
      }
