Assembler CSS is a highly performant utility-first framework that allows you to quickly prototype and build modern websites and UI components without the need to install and maintain complex software.

Usage

Incorporating Assembler CSS within your project is a trivial task. Just add a script tag before the head closing tag, and you are good to go!

<script src="https://unpkg.com/@asmcss/assembler"></script>

Now you are ready to try out Assembler CSS and write your first UI component.

<div x-style="max-w:80; mx:auto; radius:md; e:2; e.hover:4; transition:all 0.25s; cursor:pointer">
    <img x-style="block; max-w:100%; w:100%; h:auto; radius-top:md" src="https://images.unsplash.com/photo-1512621776951-a57141f2eefd?ixid=MXwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHw%3D&ixlib=rb-1.2.1&auto=format&fit=crop&w=640&q=80">
    <div x-style="p:4">
        <div x-style="text:lg; color:black; font-weight:700">Fresh veggies</div>
        <div x-style="text:sm; color:silver; font-weight:400">600g</div>
        <p x-style="pt:4">
            Any veggie can belong on your menu, so choose what you love and use the rest
            for future meals and snacks you can enjoy in flavorful ways.
        </p>
    </div>
