CSSgram
CSSGram is an Instagram filter library written in Sass and CSS.
What is This?
Simply put, CSSgram is a library for editing your images with Instagram-like filters directly using CSS. What we're doing is adding filters to the images, as well as applying color and/or gradient overlays via various blending techniques to mimic filter effects. This means less manual image processing and more fun filter effects on the web!
We're 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">. We're also on CDNJS which means another option is<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/cssgram/0.1.10/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 using only one of the styles.

Use Sass @extend or @mixin
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 😊.
- Include a link to
scss/cssgram.scssvia an@importstatement in your Sass manifest file (i.e.main.scss). It may look like:@import 'vendor/cssgram' - Extend the placeholder selector (e.g.
@extend %adenor using mixins@include aden()) in your element.
For example:
<!-- HTML -->
<figure class="viz--beautiful">
<img src="../img.png">
</figure>// Sass
.viz--beautiful {
@extend %aden;
}or using mixins (more flexible)
// Sass (without adding new CSS3 filters)
.viz--beautiful {
@include aden();
}
// Sass (adding new CSS3 filters)
.viz--beautiful {
@include aden(blur(2px) /*...*/);
}
Alternatively, if you're using only one of the styles, you can download and link any individual .scss file in your Sass manifest (i.e. scss/aden.scss).
