Change the font family globally in Material-UI 3.x

Some say you should use the jsx-global-plugin like “@global body{fontFamily:’someFont’}” , but it doesn’t work in my project. The global CSS still has the lower CSS speciality than MUI components’ CSS because this global CSS is using a type selector. You should use a theme instead //create a theme const myTheme = createMuiTheme({ typography: { […]

Class is better than interface because in interfaces you cannot define the action "type" as a constant, but in classes you can: class LoadingStartedAction implements Action{ readonly type = LOADING_STARTED } However a class instance is not a plain object, but Redux […]
