## Intro Marko is HTML _reimagined_ as a language for building dynamic and reactive user interfaces. Almost any valid HTML is valid Marko, and Marko extends HTML for building modern applications more declaratively. Among these extensions are [conditionals and lists](https://markojs.com/docs/conditionals-and-lists/), [state](https://markojs.com/docs/state/), and [components](https://markojs.com/docs/class-components/). Marko supports both single-file components and components across separate files. ### Single-file component The following renders a button and a counter of how many times the button has been pressed: **click-count.marko** ```marko class { onCreate() { this.state = { count: 0 }; } increment() { this.state.count++; } } style { .count { color: #09c; font-size: 3em; } .press-me { padding: 0.5em; } } ${state.count} Press me! ``` ### Multi-file component The same component as above, but split into: - `index.marko` template file - `component.js` component JS logic file - `style.css` component styles file **index.marko** ```marko ${state.count} Press me! ``` **component.js** ```js export default { onCreate() { this.state = { count: 0 }; }, increment() { this.state.count++; }, }; ``` **style.css** ```css .count { color: #09c; font-size: 3em; } .press-me { padding: 0.5em; } ``` ## Concise Syntax Marko also supports [a beautifully concise syntax as an alternative](https://markojs.com/docs/concise/) to its HTML syntax:

Concise syntax	HTML syntax
```marko ul.example-list for\|color\| of=[a, b, c] li -- ${color} ```	```marko ${color} ```
