How to Achieve a Fixed Bottom Footer in Ember Framework

Hello, I am working on an Ember application and trying to implement a Sticky Footer feature. I followed a tutorial on Sticky Footer On CSS-Tricks which worked for me previously, but it seems to not work with Ember.

Here is my CSS code:

.mainFooter {
     height:100px;
     color:white;
     background-color: #0c2635;
     text-align:center;
}
.wrapper {
    min-height: 100%;
    margin-bottom: -100px;
}
.wrapper:after {
    content: "";
    display: block;
}
.mainFooter, .wrapper:after {
    height: 100px;
}

This is snippet from my HTML:

<footer class="mainFooter">
    SOME TEXT
</footer>

I inspected the source code using Developer Tools and noticed that Ember adds its own wrapper around the content from the application.hbs file, which includes a class called ember-view. So, I tried this:

.ember-view {
    min-height: 100%;
}

Unfortunately, this did not resolve the issue as the footer appears in the middle of the page. Has anyone successfully implemented a Sticky Footer in an Ember app before? I would appreciate any suggestions to fix this problem.

I have uploaded the app to my server since I am not sure how to create an Ember demo on jsfiddle/codeopen. Here is the link:

EDIT
Following the suggestion by user kumkanillam, I made some changes:

In Application.hbs:

{{outlet "modal"}}
{{partial "header"}}
<div id="gif" class="wrapper">
    {{outlet}}
</div>
{{partial "footer"}}

In app.js:

App = Ember.Application.extend({
    modulePrefix: config.modulePrefix,
    podModulePrefix: config.podModulePrefix,
    rootElement: '#gif',
    Resolver
});

However, I encountered this error in the console:

ember.debug.js:43272Uncaught TypeError: Cannot read property 'tagName' of undefined

Can someone help me figure out what went wrong?

.ember-view is automatically included for all ember components, so it's not recommended to apply CSS properties directly to this class.

There are multiple approaches, but the following method should be helpful:

To ensure that your application.hbs content renders within a page-wrap div, you can wrap it as follows:

Add the following line in your index.html:

<div id="app-name" class="wrapper">
    {{content-for "body"}}
</div>

In your application.hbs:

<h1> Content </h1>
{{outlet}}  
<div id="footer">
  <p>I'm the Sticky Footer inside application.hbs</p>    
</div>

Ensure to configure the rootElement in your app.js, forcing the entire app to include it in the app-name div:

In your app.js:

App = Ember.Application.extend({
    modulePrefix: config.modulePrefix,
    podModulePrefix: config.podModulePrefix,
    rootElement: '#app-name',
    Resolver
});

Update your app.css with the necessary styling:

#wrapper {
    min-height: 100%;
    overflow: auto;
}

#footer {
    position: absolute;
    bottom: -3px;
    left: 2px;
    right: 2px;
    height: 50px;
    background-color: rgba(0, 0, 0, 0.8);
    color: #fff;
}

If you're looking for a solution that utilizes flexbox, the following code may come in handy. While flexbox might be unfamiliar to some, this answer could serve as a useful resource for future reference.

For those interested, here's a codepen showcasing minimal content within the main body: http://codepen.io/anon/pen/KgXgjV

Alternatively, you can explore the same CSS with a more substantial amount of content in the primary area by visiting: http://codepen.io/anon/pen/dpVpBK

Demonstrating why position: absolute may not be the best approach is an example accessible via:

HTML

<html>
<body>
  <div id="root" class="ember-application">
    <div id="ember332" class="ember-view">
      <div class='main-content'>
      <h1>Welcome to Ember Twiddle</h1>
        <br />

        <p>
          this page has very little content
        </p>
      </div>
      <div id="footer">
        <p>I'm the Sticky Footer. inside application.hbs</p>
      </div>
    </div>
  </div>
</body>
</html>

CSS

/* this is just to reset codepen */
/* probably not necessary on ember */
* {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
}
/* end reset */


html, body, #root {
  height: 100%;
}

.ember-view {
  display: flex;
  flex-direction: column;
  min-height: 100vh;
  background: lightblue;
}

.main-content {
  flex: 1;
}

#footer {
  width: 100%;
  height: 50px;
  background-color: grey;
}
