Generating Spritesheets

If you are not familiar with spritesheets, please read this article first

How it Works

RebelMouse provides you with tools to create spritesheet files automatically using your individual icons. The tool will create spritesheet files in both retina and non-retina formats, as well as their respective CSS markup.

To generate spritesheets for your projects use


The image folder is located in static/img/whitelabel/. All images should be located here.

A spritesheet is created for each group of files under each folder of the sprites folder.

Take as an example this set of folders:


2 spritesheet files will be created for folders ui and logos automatically by using the roar-generate_sprites command.

Spritesheets will be located here:


Stylesheets will be located here:


Step by Step

Create a folder called sprites, under static/img/whitelabel/, if it's not already created.

Create a folder for each new spritesheet you need, under sprites folder.

Put all the .png files you need into created folder. Note: images should be retina size, meaning 2x of their normal size.

Run the command roar-generate_sprites.

Import the generated CSS into your project's critical.css file, if it is not there yet.

Using the Spritesheets

Beside the spritesheet .png file, a .css file is generated as well. It contains CSS classes for all images which also handle retina displays which means you don't have to worry about high quality displays. Simply add the class to the element you want the image to show in.

For example, if your image file is located:


Then the class will be:


How to Include Interactive Elements in Posts

Enhance your articles with rich and creative media

Every article is a fresh chance to grab new readers and nurture loyal followers. This is why we give creators every opportunity to build content rich with media elements that enhance every reader's experience.

Add More Layers to Your Content

You can easily add interactive elements, like charts, to posts on our platform. For example, if you need to embed iframe code into a post, this can be done via our Add Media Bar. To do so, click the code icon (< >):

A text box will appear so you can insert your code:

Embedded Code Across Platforms

One important thing to keep in mind is that Google AMP, AppleNews, and Facebook Instant Articles will not always support embedded code. So if you use an iframe, it's best to turn off distribution to those channels for that particular post. If you have a lot of posts that require embedded code, this could be problematic for growth across those important platforms.

If you do want to use an iframe on a post destined for Google AMP distribution, it can be possible if the iframe is not at the top of the page or within the first 75% of the viewport when the page is scrolled to the top (whichever is smaller). AMP is a fast technology designed for mobile users and iframes are loaded using arbitrary timing that AMP's technology cannot ensure. For this reason, it's suggested that iframes be included in places that are not visible by users upon load.

If you have an article that needs to include an iframe at the top of the page, or within the first 75% of the viewport, AMP can be turned off for that individual article within Entry Editor.

If you don't need an interactive chart to be interactive in nature, can turn it into an image and upload it directly to your post. This way it will work on all platforms, including Google AMP, Apple News, and Facebook Instant Articles. This option, when possible, is ideal to ensure you're optimized for page speed.

Take Advantage of Shortcodes

Another great way to embed media is through our shortcodes functionality. Click here to learn more about shortcodes. Shortcodes can also inserted using the Add Media Bar. Click the brackets icon ([ ]) to choose the shortcode you want to use.

Here's an example of a chart on an article page that's been inserted using a shortcode:

Shortcodes Dashboard: Dynamic Media in Just a Few Clicks

Create multidimensional content with easy-to-find shortcodes

We believe static media is dead, and that every piece of content should be multidimensional and engaging. This is why our platform enables creators so they can add dynamic media to their content in easy and efficient ways.

One simple way to add interactive content to any post is through the use of shortcodes. Shortcodes are small snippets of code that are easier to remember than longer sequences. They typically will activate a feature or embed media into an article.
