CJSS

A CSS based web framework

Also, don’t use this project, especially not for anything serious. This is a joke and thught experiment. I won’t help you work through bugs.

To install CJSS, add the JavaScript to your website.

Using CJSS

First off, everything happens in your CSS file. You can layer this into your websites as you see fit. You can use this to layer on just a little bit more functionality in your CSS here and there or construct an entire page. It’s up to you!

HTML

To add markup to an element, select it in your CSS file, then using --html:(your markup here); add your HTML. This markup will appear everywhere that matches your CSS selector and overwrite whatever was there before. 

h1 {
  --html:(
    This is a headline
  );
}

If you wish to pass content through a component, use ${yield} . 

<component>My Component</component>
component {
  --html:(
    <h2>${yield}</h2>
    <p>This is a component</p>
  );
}

This will render as:

<component>
  <h2>My Component</h2>
  <p>This is a component</p>
</component>

JavaScript

You can use JavaScript to define the behavior of things right from your HTML. You want something to happen on a thing when you click it and don’t want to go into your JS file? Do it right from your CSS file. If you are selecting the script element it will assume you are writing a global script, but everywhere else, the keyword this will map to the selector you are in. 

.item {
  cursor: pointer;
  --js:(
    function toggle() {
      this.classList.toggle('active');
    }
    this.addEventListener('click', toggle );
  );
}

Data

You can add data to your project. Probably useful for something. Do it using the --data attribute. It should be formatted as JSON. 

nav {
  --data:(
    name: ['one', 'two', 'three'],
    link: ['#one', '#two', '#three'],
  );
  --html:(
    <a class="item" href="${data.link[0]}">${data.name[0]}</a>
    <a class="item" href="${data.link[1]}">${data.name[1]}</a>
    <a class="item" href="${data.link[2]}">${data.name[2]}</a>
  );
  --js:(console.log(data));
}
