Parallax     

Parallax scrolling is a technique in computer graphics and web design, where background images move by the camera slower than foreground images, creating an illusion of depth in a 2D scene and adding to the immersion.

Quasar provides an out of the box Vue Component you can use. It takes care of a lot of quirks, including image size which can actually be smaller than the window width/height.

Basic Usage

<q-parallax src="assets/mountains.jpg">
  <!-- Dom elements to display while loading image -->
  <div slot="loading">Loading...</div>
  <!--
    The rest of Dom elements get displayed on
    top of the Parallax image after it's loaded
  -->
  <h1>Parallax</h1>
</q-parallax>

While the underlying image is being loaded you can display a specific message through <div slot="loading">...</div>. After image has loaded, you can also display some content on top of the Parallax image (in the example above an <h1> tag).

Vue Properties

Example:

<!-- VueModel contains data property "imageURL" -->
<q-parallax :src="imageURL" :height="300">
  <div slot="loading">Loading...</div>
  <h1>Parallax</h1>
</q-parallax>
