CSSgram

CSSGram is an 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.

Browser Support

This library uses CSS Filters and CSS Blend Modes. These features are supported in the following browsers:

Chrome logo Firefox logo Internet Explorer logo Edge logo Opera logo Safari logo
43+ ✔ 38+ ✔ Nope ✘ 13 ✔ 32+ ✔ 8+ ✔

For more information, check on Can I Use.

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.

  1. 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"
  • Brannan: class="brannan"
  • Reyes: class="reyes"
  • Perpetua: class="perpetua"
  • Inkwell: class="inkwell"
  • Toaster: class="toaster"
  • Walden: class="walden"
  • Hudson: class="hudson"
  • Gingham: class="gingham"
  • Mayfair: class="mayfair"
  • Lo-fi: class="lofi"
  • X-Pro II: class="xpro2"
  • 1977: class="_1977"
  • Brooklyn: class="brooklyn"
  • Nashville: class="nashville"
  • Lark: class="lark"
  • Moon: class="moon"
  • Clarendon: class="clarendon"
  • Willow: class="willow"

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 😊.

  1. 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 or 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 just using one of the styles, you can download and link any individual .scss file in your Sass manifest (i.e. scss/aden.scss).

  4. Run gulp to compile CSS and the test site
  5. Make changes and check the test site with your changes (see file structure outline below)
  6. Submit a PR referencing the issue with a smile 😄

If you’d like to contribute, the following filters are yet to be added:

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 library
  • source/scss/ contains the source files for individual classes and placeholder selectors you can use to extend CSS classes in Sass
  • site/ is the public facing website
  • site/test is how you test filters if you're developing, remember to change is_done for the filter you're creating in site/filters.json.

Note: this will also have mixin options and a PostCSS Component.
