Angularjs – Angular Material fixed toolbar AND sticky footer

angular-materialangularjsflexboxsticky-footer

I have been beating my head against this issue for some time now and sort of came up with a solution. I would like a fixed toolbar (navbar) as well as a sticky (floating) footer. The footer should float at the bottom of the main section but be sticky to the bottom when there is no content. It seems that I can do one or the other but not both. With this method the toolbar is fixed but the footer isn't sticky. It butts up to the toolbar when the main section is empty. 

<body ng-controller="MainCtrl" layout="row">

  <div layout="column" flex>
    <md-toolbar class="md-medium-tall">
        <div class="md-toolbar-tools">
            <span>HEADER</span>
            <span flex></span>
            <md-button class="md-raised" ng-click="toggleContent(!displayContent)">onOff</md-button>
            <span flex></span>
            <md-button class="md-raised" ng-click="toggleNum()">half/full</md-button>
        </div>
    </md-toolbar>


    <md-content>
        <div layout="column" flex>
            <div ng-if="displayContent" style="background-color:SteelBlue;color:white;" ng-repeat="card in cards|limitTo: displayLim">body {{card.title}}</div>
            <div style="background-color: red;" flex></div>
            <div style="background-color:orange;color:white;" >footer item</div>
        </div>  
    </md-content>           
  </div>    
</body>

The below code works as a sticky footer but then the toolbar scrolls as well. 

<body ng-controller="MainCtrl" layout="row">

  <div layout="column" flex>
    <md-toolbar class="md-medium-tall">
        <div class="md-toolbar-tools">
            <span>HEADER</span>
            <span flex></span>
            <md-button class="md-raised" ng-click="toggleContent(!displayContent)">onOff</md-button>
            <span flex></span>
            <md-button class="md-raised" ng-click="toggleNum()">half/full</md-button>
        </div>
    </md-toolbar>

    <div layout="column" flex>
      <div ng-if="displayContent" style="background-color:SteelBlue;color:white;" ng-repeat="card in cards|limitTo: displayLim">body {{card.title}}</div>
      <div style="background-color: red;" flex></div>
      <div style="background-color:orange;color:white;" >footer item</div>
    </div>  
  </div>    
</body>

This seems like the proper flex way to accomplish what I'm trying to do but I just cant get it perfect.

Besides this method I have also used a more traditional approach of implementing a sticky footer using calculated main section height from calc(100vh - header - footer). I nearly had it figured out when BAM.. angular-material decided to make their toolbar size change with viewport size. I'm probably going to put in a change request so that I can use a gap filling <div flex></div> in the md-content section but I wanted to find out if anyone has a better solution first.

I finally figured out what the issue was. When nesting divs under the main content part of md-content there was an issue on safari. I fixed it by adding flex="none" to the top level div.

This works only on Chrome:

<md-content layout="column" flex>
 <div flex layout="column">
  <section>
    <div ng-if="displayContent" style="min-height:20px;background-color:SteelBlue;color:white;" ng-repeat="card in cards|limitTo: displayLim track by $index">{{card.title}}
    </div>
  </section>
  <div flex></div>
  <footer flex="none" style="background-color:orange;color:white;">
    <div>footer item</div>
  </footer>
 </div>
</md-content>

This works on Chrome and Safari:

<md-content layout="column" flex>
 <div flex layout="column">
  <section flex="none">
    <div ng-if="displayContent" style="min-height:20px;background-color:SteelBlue;color:white;" ng-repeat="card in cards|limitTo: displayLim track by $index">{{card.title}}
    </div>
  </section>
  <div flex></div>
  <footer flex="none" style="background-color:orange;color:white;">
    <div>footer item</div>
  </footer>
 </div>
</md-content>
