Block background color

I’ve been checking Gutenberg from time to time (without spending too much time) and literally the only thing I’m looking for is full width background (image, or solid color) with boxed content. Is this already available or it’s still in the works?

Here is simple example what I mean:

<div style="background-color: ...">
  <div class="container">
    <!-- lets say 1170px -->
    <p>Lorem ipsum</p>
  </div>
</div>

I don’t expect this to work out of the box with standard themes, but is it possible with custom themes / some modifications to exiting ones?

Thanks!
