CSSgram
Instagram filter library in Sass and CSS.
What is This?
Simply put, CSSgram is a library for editing your images with Instagram-like filters directly in CSS. What we’re doing here is adding filters to the images as well as applying color and/or gradient overlays via various blending techniques to mimic these effects. This means less manual image processing and more fun filter effects on the web!
We are using pseudo-elements (i.e. ::before
and ::after
) to create the filter effects, so you must apply these filters on a containing element (i.e. not a replaced element like <img>
). The recommendation is to wrap your images in a <figure>
tag. More about the tag here.

Usage
There are currently 2 ways to consume this library:
Use CSS classes
When using CSS classes, you can simply add the class with the filter name to the element containing your image.
- Include the CDN link in your
<head>
tag: <link rel="stylesheet" href="https://cssgram-cssgram.netdna-ssl.com/cssgram.min.css">
- Alternatively, you can download the CSSgram library locally and link to the it within your project:
<link rel="stylesheet" href="css/vendor/cssgram.min.css">
- Add a class to your image element with the name of the filter you would like to use
For example:
<!-- HTML -->
<figure class="aden">
<img src="../img.png">
</figure>
Alternatively, you can just download and link to any individual css file (e.g. <link rel="stylesheet" href="css/vendor/aden.min.css">
), if you’re just using one of the styles.
Available Classes
For use in HTML markup:
- Aden:
class="aden"

Use Sass @extend
If you use custom naming in your CSS architecture, you can add the .scss
files for the provided styles within your project and then @extend
the filter effects within your style definitions. If you think extends are stupid, I will fight you 😊.
- Download the
scss/
folder contents
- Include a link to
scss/cssgram.scss
via an @import
statement in your Sass manifest file (i.e. main.scss
). It may look like: @import 'vendor/cssgram'
- Extend the placeholder selector (e.g.
@extend %aden
) in your element.
For example:
<!-- HTML -->
<figure class="viz--beautiful">
<img src="../img.png">
</figure>
// Sass
.viz--beautiful {
@extend %aden;
}
Alternatively, you can just download and link any individual .scss
file in your Sass manifest (i.e. scss/aden.scss
), if you're just using one of the styles.

- Aden:

Filters are really fun to create! Reference photos created by Miles Croxford can be found here.
File Structure Outline
source/css/cssgram.css
contains each of the CSS classes you can apply to your <img>
to give it the filter. You should use source/css/cssgram.min.css
for production if you want access to all of the librarysource/scss/
contains the source files for individual classes and placeholder selectors you can use to extend CSS classes in Sasssite/
is the public facing websitesite/test
is how you test filters if you're developing, remember to change is_done
for the filter you're creating in site/test/index.twig
whilst gulp is running.
Note: this will also have mixin options and a PostCSS Component.
