How to set the space between two flexbox

Question

I use the flexbox material design layout and in the box I have two boxes. I am creating on jsfiddle to clarify what I mean:

Angular Material Application

I want to set a space between these fields

<div flex layout="row" layout-align="space-between center">
            <md-toolbar flex="15">
                 <h2 class="md-toolbar-tools">
                    <span>Home</span>
                  </h2>

            </md-toolbar>
                <!--How to set space between -->
            <md-toolbar>
                 <h2 class="md-toolbar-tools" layout-align="end center">
                    <span>Sign Up</span>
                    <span>Sign In</span>
                  </h2>

            </md-toolbar>
        </div>

Answer 1

I think you need a 'layout-margin' https://material.angularjs.org/latest/layout/options

<div layout="row" layout-margin>
  <div flex>Parent layout and this element have margins.</div>
</div>

Answer 2

I think you can make it a lot easier:

<md-toolbar>
    <div class="md-toolbar-tools">
        <span>Home</span>
        <span flex></span>
        <div>
            <span>Sign Up</span>
            <span>Sign In</span>
        </div>
    </div>
</md-toolbar>

You can insert a flexible element between the HOME and SIGNUP elements and it will fill the space between them.
