CSS & Style

Kweb has out-of-the-box support for the excellent Fomantic UI framework, which helps create beautiful, responsive layouts using human-friendly HTML.

Getting started

First tell Kweb to use the Fomantic UI plugin:

import kweb.plugins.fomanticUI.*

fun main() {
    Kweb(port = 16097, plugins = listOf(fomanticUIPlugin)) {
        // ...

Now the plugin will add the Fomantic CSS and JavaScript code to your website automatically.

Let’s look at one of the simple examples from the Fomantic UI documentation:

<div class="ui icon input">
  <input type="text" placeholder="Search...">
  <i class="search icon"></i>

This translates to the Kotlin:

import kweb.plugins.fomanticUI.*
import kweb.dom.element.creation.tags.InputType.*

fun main() {
    Kweb(port = 16097, plugins = listOf(fomanticUIPlugin)4) {
        div(fomantic.ui.icon.input).new {
            input(type = text, placeholder = "Search...")

Take a look at the Fomantic UI documentation to see everything else it can do.

Other UI Frameworks

Kweb is known to work well with a number of other CSS frameworks - particularly those that work through pure HTML, such as Tailwind.
